What is a PET Scan and its uses

Learn more about PET Scans


A PET scan, or Positron Emission Tomography scan, is a medical imaging technique used to observe metabolic processes in the body. It involves injecting a radioactive tracer substance, usually a type of sugar, into the bloodstream. As cells in the body absorb this tracer, they become visible on the PET scan images.




Some uses are:


1. Cancer Imaging: PET scans are highly effective in imaging and detecting various types of cancers by highlighting areas with increased metabolic activity.


2. Cardiac Assessment: They can evaluate blood flow to the heart and identify damaged or scarred heart tissue.


3. Neurological Studies: PET scans are used to study brain function, aiding in the diagnosis and monitoring of conditions such as Alzheimer's disease.


4. Infection Detection: PET scans can help identify infections and inflammation in the body based on increased metabolic activity.


5. Monitoring Treatment Response: PET scans are valuable in assessing the response to cancer treatment, allowing for adjustments to the treatment plan if necessary.
