Diagnostic Role of 18F-FECH-PET/CT Compared with Bone Scan in Evaluating the Prostate Cancer Patients Referring with Biochemical Recurrence

Shape of choline uptake in sclerotic and mixed bone metastases. (a) Osteoblastic metastasis in vertebra: the radioactivity concentrates in the rim (low sclerosis level). (b) Osteoblastic metastasis in ischium: we notice negative uptake in the area of metastasis with a high sclerosis (1); here the activity from part 2 can spill into part 1, which in turn will lead the examiner to think that there may be more viable tumor tissue within the osteoblastic part than there really is. (c) Mixed metastasis: we notice the radioactivity concentration in osteolytic part.
