PET scans excel in providing functional information about cellular activity, making them valuable in oncology, cardiology, and neurology. CT scans offer detailed anatomical images, commonly used for diagnosing fractures, tumours, and infections. MRIs are ideal for imaging soft tissues, joints, and the brain, without exposure to ionizing radiation. Understanding the differences between these imaging modalities allows healthcare professionals to select the most appropriate technique based on the patient's clinical needs and the desired diagnostic information.

How does a PET scan work?

A PET scan, or Positron Emission Tomography, works by detecting radioactive tracers injected into the body. These tracers, typically glucose-based compounds, are absorbed by cells and emit positrons, which collide with electrons, releasing gamma rays. Detectors surrounding the body then capture these gamma rays, creating detailed images of metabolic activity. Areas with high metabolic rates, such as tumours, appear as bright spots on the scan, providing valuable information about cellular function and disease presence. PET scans are commonly used in oncology, cardiology, and neurology for accurate diagnosis, staging, and treatment monitoring.

Why is a PET scan performed?

A PET scan, or Positron Emission Tomography, is performed for several reasons. It is primarily used in oncology to detect and stage cancer, assess treatment response, and monitor disease progression. PET scans are also valuable in cardiology for evaluating heart function, identifying areas of reduced blood flow, and detecting myocardial viability.

PET scans are performed for various reasons, including:

• Cancer detection and staging: PET scans are highly effective in detecting and staging various types of cancer, aiding in treatment planning and monitoring.
• Assessment of treatment response: PET scans help assess how well cancer treatments such as chemotherapy or radiation therapy are working, guiding further management decisions.
• Evaluation of heart function: In cardiology, PET scans are used to evaluate heart function, detect coronary artery disease, and assess myocardial viability.
• Diagnosis of neurological disorders: PET scans are valuable in neurology for diagnosing conditions such as Alzheimer's disease, epilepsy, and brain tumours, by providing detailed images of brain metabolism and activity.
• Psychiatric studies: PET scans play a role in psychiatry by studying brain metabolism and neurotransmitter activity, aiding in understanding conditions such as depression and schizophrenia.

Overall, PET scans provide critical functional information about cellular activity, enabling accurate diagnosis and tailored treatment plans for various medical conditions.

How do you prepare for a PET scan?

Preparing for a PET scan involves several steps to ensure accurate results. Patients are typically instructed to fast for several hours before the scan, avoiding food and drinks containing sugar. It's essential to inform the healthcare team about any medications being taken, as certain medications may interfere with the scan. Patients should also avoid strenuous physical activity in the hours leading up to the scan. Wearing comfortable clothing and removing metal objects or jewellery is recommended. Lastly, patients should follow any specific instructions provided by their healthcare provider to ensure a smooth and successful PET scan procedure.

Results and follow-up

After undergoing medical tests or procedures, receiving timely and accurate results is crucial. The results provide valuable insights into one's health status, enabling healthcare professionals to make informed decisions regarding treatment and management. Following up on these results is equally important to discuss findings, address concerns, and plan next steps. This may involve scheduling additional tests, adjusting medication regimens, or implementing lifestyle changes. Regular follow-up appointments ensure ongoing monitoring of health conditions, track progress, and identify any emerging issues promptly. Effective communication between patients and healthcare providers during this process fosters collaboration and promotes optimal health outcomes.

Types of PET scan machine

PET scan machines come in different types, each offering unique features and applications:

• Full-ring PET scanners: These machines consist of a complete ring of detector modules surrounding the patient, allowing for simultaneous imaging of the entire body.
• Partial-ring PET scanners: These scanners have a partial ring of detector modules, enabling faster imaging with reduced cost and complexity.
• Hybrid PET/CT scanners: Combining PET with computed tomography (CT) technology, these machines provide both metabolic and anatomical imaging in a single session, enhancing diagnostic accuracy.
• Hybrid PET/MRI scanners: Similar to PET/CT scanners, these machines combine PET with magnetic resonance imaging (MRI), offering detailed anatomical and functional imaging with superior soft tissue contrast.

Each type of PET scan machine has its advantages and applications, catering to specific clinical needs and imaging requirements.

How does PET scan machine work

A PET scan machine works by detecting positron-emitting radioactive tracers injected into the body. These tracers accumulate in areas of high metabolic activity, such as tumours or areas of inflammation. As the tracers decay, they emit positrons, which collide with nearby electrons, producing gamma rays. The PET scanner detects these gamma rays and creates detailed images of the body's internal structures. By measuring the distribution of radioactive tracers, PET scans provide valuable information about cellular activity, allowing healthcare professionals to diagnose diseases, assess treatment responses, and monitor patient health with precision.
