PET CT: Operation and uses of this hybrid equipment

by Luis Daniel Fernádez | Feb 14, 2025 | Equipment analysis

The PET technique CT consists of the integration of two imaging technologies in the same medical equipment: Positron Emission Tomography (PET) and Computed Axial Tomography (CT). The first PET-CT prototype was developed at the University of Pittsburgh in 1998 and its commercialization began in 2001, making it one of the first PET-CT scanners in the world. the most innovative and up-to-date equipment of the area of diagnostic imaging.

A PET CT system is a hybrid medical equipment with a stretcher and a shared medical image acquisition systemThe combination of both technologies provides a tomographic image that represents a cross-section of the organism, offering anatomical and functional information of the interior of the human body. The combination of both technologies provides a tomographic image that represents a cross section of the organism, offering anatomical and functional information of the interior of the human body.

On the one hand, the technology of Positron Emission Tomography or PET scanning provides functional and molecular information of the tissues through the use of a radiopharmaceutical. Therefore, it allows the quantification of various biochemical processes. From cellular metabolism, blood flow and protein synthesis to the analysis of different receptors. For its part, the Computed Axial Tomography or CT reports the different tissue densities generating a high-resolution anatomical image.

Thus, by combining the two techniques in a single integrated PET CT systemcan be generated anatomical and functional images simultaneously. As a result, more complete and efficient clinical diagnoses are offered, both in terms of sensitivity and specificity. Through its ability to detect functional alterations before they are visible in conventional studies, PET CT is fundamental in the early detection of diseases and in the evaluation of the effectiveness of treatments. Especially in enceological, neurological and cardiac diseases. In the following article, we analyze how it works and its main uses in clinical practice.

How does the hybrid PET CT equipment work?

The medical image acquisition protocol in a PET CT study is similar to the procedure for the standard PET technique. In a PET CT scanner, the acquisition of the study consists of three phases: the performance of a topogram, the performance of a CT study that will make it possible to determine the attenuation correction of the PET technique and, finally, the acquisition of the Positron Emission Tomography (PET). Each of these phases is discussed below:

Patient preparation

Before performing a PET CT study, the patient must be properly prepared so that the medical images obtained are of optimum quality. First of all, a radiopharmaceutical is administeredThe most widely used is Fluorine-18-labeled Fluorodeoxyglucose (18F-FDG). This compound makes it possible to detect areas of high metabolic activity that often arise in certain types of cancer, neurological and cardiac diseases. The radiopharmaceutical is administered intravenously and the patient must wait between 45 and 60 minutes for it to distribute correctly by the agency prior to the start of image acquisition.

For optimal uptake of the radiopharmaceutical, the patient must follow a series of medical recommendations:

• Fasting for at least 4-6 hours before the study.which avoids interference with glucose metabolism.
• Staying well hydrated before and after of the procedure.
• Control blood glucose levelsThe high levels may affect the uptake of the radiopharmaceutical.
• Follow instructions from physical rest before the study. Excessive movement prior to the study may generate unwanted FDG accumulation in the muscles.
• In some cases, a controlled breathing protocol to improve the quality of the CT image.

2. Positioning of the patient in the tomograph

Once the waiting period after injection of the radiopharmaceutical is over, the patient is placed on the bed of the PET CT scanner.. To obtain high quality images and reduce errors in PET and CT image superimposition, it is essential that the patient is well aligned and comfortable. In turn, The patient is asked to extend the arms over the head. if possible, to reduce interference in the images of the thorax and abdomen. On the other hand, metal objects are removed and elements that may affect image quality.

Subsequently, the position of the stretcher is adjusted according to the area to be examined, ensuring that the body is well aligned with the CT scanner detectors. In this process, patient immobility is crucial to avoid blurred images and improve diagnostic accuracy.

3. Making the topogram

The first step in the examination of the patient is to perform a topogram with the PET CT equipment. The images are obtained using the X-rays in a fixed position, which can be anterior, posterior, lateral or in an intermediate orientation. The acquisition is performed with a continuous movement of the stretcher in a predetermined range. In this way, a anatomical image similar to an X-ray projectionwhere the different internal structures and tissues can be analyzed.

It is important that during the procedure the equipment is adjusted and the limits of the PET CT study are defined. Depending on the model of the CT scanner, the fields of view and image formation may be different for different techniques. Therefore, it is necessary to verify that all body parts are within the image with the smallest field of viewwhich are normally those of the CT scan.

4. Elaboration of the TAC study

Once the field of view of the PET CT study has been defined, the patient's stretcher is automatically mobilized to start the CT diagnosis. In the test, a specific breathing protocol is introduced to match the CT and PET image, since the latter is acquired with normal breathing by the patient.

The duration of the CT study depends on various parameters: the extension of the area to be scanned, the rotation speed of the tube and the translation of the stretcher. CT allows detailed anatomical images to be obtained through the use of X-rays, which facilitates the precise localization of organs and structures. In some cases, a contrast medium may be administered to enhance the visualization of vascular structures or specific lesions.

Regarding its duration, a full body CT study using the hybrid equipment is less than one minute. This is because the images obtained are used for attenuation correction in the PET study, which significantly reduces the acquisition time. In PET equipment, when germanium (Ge) sources are used, the CT procedure time amounts to 20 to 30 minutes. With this, radiation exposure is reduced and the patient experience is improved.

5. Acquisition of the PET study

After the CT analysis, PET images are acquired, in which the metabolic data of the tissues are captured. For this purpose, the couch is moved to position the patient in the field of view of the PET scanner, encompassing different positions on the stretcher to cover the region of interest to be analyzed. All these areas are the ones that cover the range explored by CT.

The acquisition time of the PET study can range from between 10 and 30 minutes. This depends on the stretcher positions, the range scanned, as well as the equipment used. During this phase, the areas of the body with abnormal metabolic activity are highlighted on the PET imageThis makes it possible to detect tumors, infections or neurological problems with great precision.

6. PET CT image reconstruction

Reconstruction is performed in parallel to image acquisition.This allows results to be obtained in just a few minutes. This step is essential to generate highly accurate fused images, combining the metabolic information from PET with the detailed anatomical structure from CT.

In this process, the reconstruction time of each CT slice is less than one second.The PET images are reconstructed and available for analysis at the end of the acquisition of the last couch position. To achieve this, we use the reconstruction algorithms available in PET tomographs with the scatter and attenuation corrections determined from CT images.

7. Image analysis and interpretation

Once the images have been reconstructed, they are analyzed, where specialists can analyze different types of medical images:

• PET images without correctionThey show the uptake of the radiopharmaceutical in the body.
• Corrected PET imagesThey incorporate attenuation adjustments to improve accuracy.
• CT imagesThey offer anatomical details of the explored region.

The image fusion software allows the superimposition of PET and CT information, facilitating the exact localization of lesions and their subsequent analysis and interpretation.

What is PET CT used for?

It is a diagnostic technique that is essential in different medical specialties:

• OncologyEarly detection of tumors, evaluation of metastases and treatment follow-up.
• NeurologyIt is used for the diagnosis of diseases such as Alzheimer's, Parkinson's and epilepsy.
• CardiologyThey play an essential role in the evaluation of blood flow and the detection of lesions and abnormalities in the heart.
• Immunology and infectionsHelps in the identification of inflammatory processes and infectious diseases.

Clinical applications of PET CT

PET CT technology combines the advantages of an anatomical and a functional imaging technique. In the current medical context, the use of this hybrid equipment is used in the following cases:

To confirm or rule out a malignant tumor pathology.

The PET technique can to analyze whether a lesion is benign or malignantThis can avoid the need for biopsies and other invasive diagnostic tests. In turn, it allows early detection of tumor processes, before anatomical changes occur that can be detected by morphological imaging techniques.

Determine tumor extent

It has the ability to perform whole body studieswhich makes it possible to rule out or confirm other malignant lesions concurrent with the primary tumor.

Detecting new tumor recurrences

Through this technique, it is possible to differentiate between malignant processes and new tumors that arise recurrently. This can be used to optimize patient treatment planning.

Assess response to treatment

The metabolic changes produced before an adequate response to chemotherapy are observed earlier in PET imaging than in other techniques. diagnostic imaging. Therefore, this type of medical imaging is an early indicator of tumor response. Their use helps to determine the continuation of certain treatments or, on the contrary, their interruption.

The use of hybrid PET-CT equipment is a crucial advance in medical diagnostics. It combines a functional and anatomical analysis of the inside of the human body in a single medical device, making it fundamental in the early diagnosis of cancer and other neurological and cardiological diseases. The combination of technology and medicine continues to save lives, and the PET CT technique is a clear example of this.

What is positron emission tomography or PET?

by Luis Daniel Fernádez | Jan 31, 2025 | Equipment analysis

The positron emission tomography (PET) scanning is the technique of diagnostic imaging more recent and modern. It is a nuclear medicine procedure that emerged in the 1970s in the United States and was introduced in Spain in 1995. To perform a positron emission tomography scan, a radioactive material, called a radiopharmaceutical, is administered intravenously and the diagnosis is then made using specific equipment: the PET scanner.

This medical device is equipped with a special camera that allows visualization of internal organs at the molecular and cellular leveloffering information on metabolic activity of the body's tissues. From the analysis of blood flow, oxygen consumption, glucose and protein metabolism, amino acid transport and cell division to the detection of biochemical changes.

In the PET technique, radioation is detected after administration of the radiopharmaceutical. To do this, you need a waiting time between 30 and 60 minutes for the substance to take effect and be distributed correctly throughout the patient's body. This diagnostic imaging test is used for to develop a metabolic study of the interior of the organismIt therefore provides a complement to the anatomical information offered by procedures such as computed tomography (CT) or magnetic resonance imaging (MRI).

One of the most recent advances in this area has been the development of hybrid equipment that combines two technologies in the same medical equipment. In 1998, the CT scanner began to be used in clinical practice. PET CTa device that incorporates the PET technique together with CT. A year earlier, in 1997, the hybrid PET MRI device was created by Mardsen and Cherry, which combines the anatomical images provided by MRI with the biochemical data from PET. However, it was not until 2009 that Phillips developed the first integrated system.

Currently, the use of positron emission tomography (PET) has made it possible to diagnose diseases in their earliest stages and, in turn, analyze the patient's response to specific treatments. Its ability to analyze functional changes before structural damage occurs in the body makes it key in the diagnosis and monitoring of multiple pathologies, especially in oncology, neurology and cardiology.

In the following article, we will analyze what this diagnostic technique consists of and the medical equipmentThe advantages and disadvantages, as well as their applications in clinical practice.

How does PET positron emission tomography work?

The positron emission tomography diagnosis consists of a process made up of different stages, which we analyze below:

Administration of the radiopharmaceutical

The first step in a PET study is the administration of a radioactive substancecalled radiopharmaceutical or radiotracer. This compound is generally introduced into the body intravenously, although in some cases it can be administered by inhalation or orally.

The most commonly used PET radiopharmaceutical is fluorodeoxyglucose (FDG). It consists of a glucose-like molecule that is labeled with fluorine-18, a radioactive isotope. The main reason for using FDG is that cells with high metabolic activity, such as cancer cells, consume more glucose than normal tissues. This allows the radiopharmaceutical to accumulate in areas of higher cellular metabolism, facilitating its detection.

2. Distribution and waiting

After administration of the radiopharmaceutical, the patient must remain at rest for 30 to 60 minutes for the substance to be adequately distributed throughout the body. During this time, it is recommended that the patient remain calm and avoid talking or moving excessively, since muscular activity could alter the uptake of the radiotracer and affect the quality of the images.

3. Patient positioning

Once the radiopharmaceutical has been absorbed by the tissues, the patient is placed on a sliding stretcher which introduces it into the PET scanner.. This equipment consists of a ring of detectors that surrounds the patient and is capable of recording the radiation emitted by the radiopharmaceutical. The procedure has a duration between 15 and 45 minutesdepending on the type of study to be performed.

4. Diagnosis by PET scanner

The radiopharmaceutical injected into the patient emits positrons.which collide with the body's electrons, generating two gamma photons in opposite directions. The PET scanner detectors capture these gamma photons and record the exact location of each emission. Subsequently, the medical team is responsible for the reconstruction of a tomographic image detailed with the areas where the radiopharmaceutical has accumulated, reflecting the metabolic activity of tissues and organs.

5. Image processing and reconstruction

Once the data has been collected, specialized software processes the information and generates three-dimensional images of the distribution of the radiopharmaceutical in the patient's body. These images show the areas of increased metabolic activity (hyper uptake) in brighter colorswhile areas with lower metabolism appear in darker shades. This activity map allows physicians to accurately identify anomalies such as malignant tumors, neurodegenerative diseases or cardiac conditions.

6. Analysis and interpretation of results

Finally, specialists in radiology or nuclear medicine analyze the images. obtained to make a diagnosis. Depending on the case, the PET scan can be combined with other imaging techniquesas the computed tomography (CT) or the magnetic resonance imaging (MRI)as well as the use of hybrid equipment. This will provide a more complete view of the anatomy and function of the organs.

Positron emission tomography advantages

Positron emission tomography (PET) is a highly advanced imaging technique with the following benefits:

Early detection of diseases

Allows you to identify metabolic abnormalities before visible structural changes occur in other imaging tests, which facilitates the early diagnosis of diseases. These include cancer, Alzheimer's disease and heart disease.

Real-time functional evaluation

In contrast to computed tomography (CT) or magnetic resonance imaging (MRI), which only analyze anatomy, PET provides information on how tissues and organs function at the cellular and molecular level.

Effective technique to detect cancer and metastases

PET is one of the most effective tools for the detection and localization of cancer and its metastasesThis allows us to know the extent of the disease and to plan the appropriate treatment.

Monitoring treatment response

This is a diagnostic technique used for evaluate how a patient is responding to chemotherapy, radiotherapy or immunotherapy treatments. In this way, it makes it possible to make adjustments to the therapeutic strategy in real time.

Combined technology for greater precision

The use of hybrid equipment allow both anatomical and functional information to be obtained at the same time. At present, PET-CT and PET-MRI equipment offer the most advanced benefits of using two techniques in a single study. Its use helps to improve diagnostic accuracy and radiation dose reduction received by the patient by up to 50 %.

Disadvantages of positron emission tomography

However, it also has a number of limitations that are important to analyze:

Exposure to ionizing radiation

The PET technique uses radioactive radiopharmaceuticals that expose the patient to ionizing radiation. Although its doses are low and safe, the amount of radiation increases significantly when using various diagnostic techniques.

High cost and limited availability

It is a expensive technique because of the need for specialized equipment and the use of radiopharmaceuticals. These substances require rapid distribution in order not to lose effectiveness. Therefore, one of their disadvantages is that they limit availability in certain hospitals and regions.

Waiting time and duration of the study

Before performing the PET scan, patient must wait 30 to 60 minutes after injection of the radiopharmaceutical. Thus, in comparison with other diagnostic techniques, waiting time increases the duration of the test.

Complex interpretation of images

Medical images obtained can be difficult to interpret.not all elevated glucose uptake indicates abnormalities. Therefore, alternative tests are required for a more accurate diagnosis.

Clinical uses and applications

Positron emission tomography is used in different medical specialties, specifically in oncology, neurology and cardiology. What are its main uses in clinical practice?

Oncology

• Early detection of malignant tumors.
• Identification of metastases and evaluation of cancer spread.
• Assessment of the response to treatment with chemotherapy or radiotherapy.
• Differentiation between benign and malignant tumors.

Neurology

• Early diagnosis of neurodegenerative diseases such as Alzheimer and Parkinson.
• Localization of epileptic foci in patients with treatment-resistant epilepsy.
• Evaluation of psychiatric illnesses and neurocognitive disorders.

Cardiology

• Determination of cardiac muscle viability in patients with myocardial infarction.
• Evaluation of blood flow and cardiac function in ischemic diseases.

Other medical applications

• Diagnosis of endocrine diseases, such as adrenal gland disorders.
• Detection of infections and chronic inflammatory diseases.
• Evaluation of gastrointestinal pathologies with metabolic involvement.

After analyzing the operation of positron emission tomography (PET), we can highlight that it is a fundamental tool in nuclear medicine to detect diseases in their early stages and evaluate the metabolic function of different organs and tissues.

Parts of a mammography machine, operation and advantages

by Luis Daniel Fernádez | Jan 16, 2025 | Equipment analysis

The mammography is a technique of diagnostic imaging which uses a system of low-dose X-rays to examine the inside of the breasts. This is a medical test that consists of performing a breast radiography. When performing a mammogram, a mammography machine is used. specific equipment: the mammograph. It is a medical equipment that is specifically designed to capture X-ray images with a high resolution to detect signs and irregularities in breast tissue. The design and the different parts of a mammography equipment allow using a minimum dose of radiation during the test, making it an effective, fast and safe examination.

Health professionals use this test to look for early signs of disease in breast tissue. Among them, breast cancer. The mammography test is called mammogram and its main purpose is to detect abnormalities such as tumors, cysts or microcalcifications in the breast. We analyze, below, what mammography consists of, how the mammogram works and its different parts.

Mammography: What is mammography and types of mammograms?

The use of the mammograph is used as a screening tool for early detection of breast cancer in womenA mammogram is used both in women who have no symptoms and to diagnose the presence of abnormalities in women who notice breast irregularities. A mammography examination or mammogram exposes the woman to a small dose of ionizing radiation to generate medical images of the inside of the breasts. We can differentiate between two types of mammography:

Screening mammography

A screening mammogram is performed in women who have no signs or symptoms of breast cancer. This type of mammography should be performed periodically in women from the age of 40 as a form of prevention. By means of this diagnostic test, it is possible to detect irregularities in the breast tissue, such as tumors, cysts or microcalcifications. Screening for breast disease at early stages, especially breast cancer, provides a range of advantages:

• Allows the identification of tumors before they are palpable. or present visible symptoms.
• Enables treatment to be initiated in the early stagesbefore the disease has spread.

According to different studies, it has been proven that the screening mammography screening decreases breast cancer morbidity rates by detecting the disease at treatable stages, increasing the chances of successful treatment.

2. Diagnostic mammography

Diagnostic mammography is used when a woman presents symptomsas lumps, pain, discharge or changes in the skin of the breast. It is also used when an abnormality is detected on a screening mammogram or detection. This type of examination allows the affected area to be studied in greater detail and thus identify whether the breast condition is benign or malignant.

Mammograph operation

The medical equipment The mammogram is a specialized medical device that allows the analysis of breast tissue and the presence of abnormalities. This is specialized medical equipment that uses X-rays to generate medical images of the inside of the breasts. How a mammogram works consists of several stages:

Preparation of the patient

The process begins with the positioning of the patient in front of the mammograph. During the mammogram, a radiology professional will positions the breast on a flat platform of the mammography equipmentwhere the breast will be gradually compressed. The specialized technician will guide the patient to ensure proper posture and perform the medical test.

2. Breast compression

Once the breast is positioned, an adjustable compressor descends to press on the breast tissue gently, but firmly.

3. X-ray emission

The tube of X-rays of the mammogram emits a controlled beam of radiation passing through compressed breast tissue. This radiation is absorbed to a greater or lesser extent depending on the density of the tissue:

• The dense tissuessuch as tumors or microcalcifications, absorb more radiation. They appear clearer and brighter in the images.
• On the other hand, the fatty tissues absorb less radiation and appear darker.

4. Image capture

The radiation passing through the breast is captured by a detector which transforms the data into a digital image or radiographic film. Modern mammographs are often equipped with digital technology that allows images to be stored and processed on a computer.

Subsequently, these generated medical images can be integrated in the RIS system to automate the management of medical imaging data and information, facilitating its analysis and comparison with previous studies.

5. Variation of angles and views

To ensure a complete evaluation of the breast tissue, images are captured from different angles. The different perspectives help physicians identify abnormalities that may not be visible in a single view. The views that are analyzed in a mammography study are:

• Craniocaudal (CC)This is a top-down view.
• Mediolateral oblique (MLO)This type of slanted view allows a greater amount of breast tissue to be studied, especially that close to the axilla.

6. Image analysis

Once the images have been obtained, a specialized radiologist reviews the results for possible abnormalitiesas cysts, calcifications, tumors or suspicious tissue changes. Nowadays, digital images offer many advantages, since they allow adjusting contrast and brightness to improve image quality, obtaining a more efficient and accurate diagnosis.

The mammograph: Parts and components

A mammogram is composed of several elements that work together to ensure clear and accurate images. Each component has a specific function that contributes to the quality of the diagnosis and the safety of the procedure. What are the main parts of a mammography machine?

X-ray tube

The X-ray tube is the component responsible for generating the X-ray beam that passes through the breast tissue. and subsequently produce high quality images. The mammograph uses a lower radiation doses than standard X-rays. This is because, since x-rays do not pass through this area easily, the mammography equipment is designed with two plates that compress and flatten the breast to separate the breast tissue. In this way, a higher quality medical image can be created and the amount of radiation during the exam can be reduced.

2. Compressor

The compressor is a movable plate that descends to press the breast against the mammography platform. Its function is to compress the breast tissue gently and firmly, providing the following advantages:

• Reducing the thickness of breast tissue to improve the visualization of internal structures.
• Minimizing X-ray scatteringThe image quality is improved.
• Avoid blurred images caused by the involuntary movement of the patient.
• Allowing the use of a lower dose of radiationmaking the procedure safer.

3. Support platform

The support platform is a flat surface on which the breast is positioned during mammography. It provides a stable and firm foothold, ensuring that the breast tissue is correctly positioned for sharp, detailed images.

4. Detector

The detector is the component that captures the radiation passing through the breast tissue and converts it into an image.. Depending on the type of mammograph, it can be of different types:

• DigitalX-ray: Converts X-rays into electronic data that is processed and stored in a computer, facilitating detailed and rapid analysis.
• Radiographic filmThis type of detector is used in analog mammographs, where the image is printed on a special film.

5. Collimator

The collimator is a structure that directs and confines the X-ray beam to the specific area of the breast that needs to be examined. This component prevents other areas of the body from receiving unnecessary radiation, making the procedure safer.

6. High voltage generator

The high-voltage generator is responsible for supplying the energy necessary for the X-ray tube to function correctly. It regulates the intensity and duration of the X-rays, adapting to the needs of each scan.

7. Control station

The control station is the panel or computer from which the technician operates the mammography machine. Allows you to adjust the parameters of the examinationIt also ensures that the procedure is performed in a precise and customized manner for each patient. It also ensures that the procedure is performed accurately and customized for each patient.

8. Positioning system

The positioning system includes mechanisms for adjusting the height, tilt and angle of the mammography machineThe system can be adapted to the physical characteristics of each patient. This system facilitates the imaging from different perspectivesobtaining a complete analysis of the breast tissue.

9. Image processing software

In digital mammographs, the digital mammogram processing software medical images is an advanced tool that improves the quality of captured images. Allows adjustment of contrast, brightness and other parameters to highlight specific details, as well as compare current images with previous studies, facilitating a more accurate diagnosis.

10. Security system

The mammogram is equipped with a safety system that ensures that radiation exposure is minimized and safe for the patient. In addition, some devices are equipped with sensors that automatically stop the process if a problem is detected technical or positioning.

Advantages of mammography

The mammograph is an essential medical device for the detection, diagnosis and follow-up of breast diseases, especially breast cancer. Its use not only allows early identification of abnormalities, but also contributes to more effective treatment planning. What are its main advantages?

Prevention and early detection of diseases

The mammograph is capable of identify abnormalities in breast tissue in early stages or even before symptoms and signs are visible. The early detection is key to significantly increasing the chances of successful treatment, as it allows the disease to be addressed before it develops to an advanced stage.
