Research on SUV levels

Well I could not stand not knowing what suv meant in pet scans.   It measures cellular activity in the absorption and  processing of the yucky stuff they make you drink for the test.  An suv level above 2.5 means that it possibly could be a cancer which is a fast “eater”.  Many things affect a pet scan, weight, length of fast, any movement, etc. etc….. so,  I now know something that I did not earlier know.
Knowledge is power,  I suppose, but a little knowledge is kinda dangerous.   The human quest for knowledge is overall a good thing. Curiousity whilst killing the cat might inform the homo sapien and quiet his fears?  The verdict, as I tell my clients is not yet in.  Pun intended .
