PET/CT scan

Learn about what’s happening inside your body with positron emission tomography (PET) and computed tomography (CT) at Montage Health’s Community Imaging Center.

What is PET/CT imaging?

PET/CT tests combine nuclear imaging with computed tomography.

PET measures blood flow, oxygen use, sugar metabolism, and other activities in the body. It reveals how well certain organs and tissues work. A CT scan shows the structure of those tissues and organs. Together, the two types of technology create the most detailed images possible, so you get an accurate diagnosis.

Why do I need a PET/CT scan?

PET/CT tests can help your doctor:

Detect cancer, see where it has spread, or check the success of cancer treatment
Examine blood flow to the heart or look for damage after a heart attack
Learn about brain tumors, memory disorders, seizures and other problems that affect the nervous system
Record normal brain and heart function
