Skeletal metastases are the most common variety of bone tumors, particularly in the elderly patients. PET Quantification The standardized uptake value (SUV) is a semiquantitative measure of the tracer uptake in a region of interest that normalizes the lesion activity to the injected activity and a measure of the volume of distribution (usually total body weight or lean body mass). Sometimes, everything may look good and a tumor may shrink or even disappear. Hi I was wondering if anyone could help me put this in terms a non doctor can understand ie (Me).
