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

Figure 11

Inhomogeneous therapy effect on the different bone metastases: 63-year-old PCA patient with known bone metastases was referred shortly after chemotherapy onset. (a) MRI T1-weighted coronal and sagittal planes. (b) ¹⁸F-FECH-PET/CT, coronal and sagittal planes (c). Bone scan (posterior view). In the upper thoracic spine (curved arrow) both CT and MRI show bone metastasis without PET correlation ((b) lower images). By contrast, bone scan demonstrates this metastasis clearly. In middle thoracic vertebrae (straight arrow), both CT and MRI show another bone metastasis; it is of positive choline and MDP uptake.
