Positron Emission Tomography (PET) Scans and Computerized Tomography (CT) Scans

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.
