Full Body PET-CT with 18F-FDG

A Positron Emission Tomography (PET) scan is an imaging test that uses radioactive substance to measure important body functions. These scans can show how well organs and tissues are working, which are useful for disease detection before it is evident on other imaging tests.

Most PET scanners now have an integrated CT scanner to provide improved anatomic localization and more accurate interpretation of the PET images.
