What is a PET/CT SCAN

Positron emission tomography (PET), also called PET imaging or a PET scan, is a type of nuclear medical imaging that produce 3 dimension images of biological functions. PET scans can not only diagnose health conditions, but are helpful in determining how a condition is developing.

Nuclear medicine imaging procedures are primarily noninvasive and usually painless medical tests that use radioactive materials called radiotracers. Radiotracers are designed to bond with certain chemicals within the body, like glucose, and highlight areas that are using those chemicals.

PET scans are often combined with X-rays, MRIs or CT scans to produce a more complete picture that can pinpoint disease centers in the body. Combining multiple types of imaging gives physicians more precise information and leads to more accurate diagnoses of cancer, heart disease and brain disorders.

Benefits of a PET/CT Scan​

Risks of a PET/CT Scan​

The PET scan involves radioactive tracers, but the exposure to harmful radiation is minimal. The risks of the test are minimal compared with how beneficial the results can be in diagnosing serious medical conditions. The tracer is essentially glucose (sugar) with the radioactive component attached. This makes it very easy for your body to eliminate the tracers, even if you have a history of kidney disease or diabetes.
