Are all hotspots on PET scan cancer?

PET Scans and CAT Scans

Best Answer

Abnormal cells in the body that use a lot of glucose will also appear as "hot spots." Cancer cells are highly metabolic and use a lot of sugar.

PET scans do not diagnose cancer; they only show areas of abnormal uptake of the tracer material.

Other diseases can produce "hot spots," such as infection.
