A positron emission tomography (PET) scan is a type of nuclear medicine imaging exam that uses a small amount of radioactive material to show activity inside the body. Computerized tomography (CT) scans use special X-ray equipment to create a detailed view of internal systems. A combined PET/CT scan gives physicians a very precise view inside the body and leads to more accurate diagnoses for complex conditions.
What you should know about PET/CT scans
- Depending on the type of PET/CT scan being performed, the radiotracer (a short-lived, low-energy radioactive material) is intravenously injected (IV) into a patient.
- PET/CT scans are noninvasive and painless with the exception of possible discomfort from the intravenous injections.
- In addition to diagnosing and determining the severity of various diseases, PET/CT scans can also be used to immediately see a patient’s response to specific treatments.
