Diagnostic Role of 18F-FECH-PET/CT Compared with Bone Scan in Evaluating the Prostate Cancer Patients Referring with Biochemical Recurrence
Figure 12
73-year old patient with prostate cancer metastatic to regional lymph nodes (a) and thoracic spine (b). Lower row: baseline Upper row: followup after 6 months under AHT. Bone metastasis (b) shows a dramatic SUV (max) decreasing (8.9 versus 4.47); however, the associated CT shows an increasing of sclerosis degree (HU 348 versus 613) suggesting progressive disease in spite of SUV decline. The lymph node metastasis (a) shows a SUV(max) rising (8.1 versus 9.6), confirming thus the progress.
