Example of metabolic assessment in a patient with metastatic bone evolution. (A) First examination: initial evaluation with multiple bone lesions (SUVmax = 11.8; SUVpeak = 7.1); (B) second examination: partial metabolic response on bone (SUVmax = 3.4 or 71% decrease; SUVpeak = 1.5 or 78% decrease); and (C) third examination: disease progression with new lesions and recurrence of some initial hypermetabolic lesions (SUVmax = 6.4 or 46% increase; SUVpeak = 4.3 or 65% increase). Persistence of sclerosis on all CT images does not allow to evaluate the response.
