What Is SUV on a PET Scan? | Healthfully

Posted: (5 days ago) A positron emission tomography (PET) scan creates images of cell activity, using standardized uptake value (SUV) as a measurement 1. SUV describes the level of activity in a particular spot compared to activity elsewhere in the body. An SUV reading of 1 is baseline or normal celluar activity.
