Imaging of prostate cancer with PET/CT using (18)F-Fluorocholine.

While (18)F-Fluorodeoxyglucose ((18)F-FDG) Positron-Emission Tomography (PET) has limited value in prostate cancer (PCa), it may be useful for specific subgroups of PCa patients with hormone-resistant poorly differentiated cell types. (18)F-Fluorocholine ((18)F-FCH) PET/CT has been increasingly used in primary and recurrent PCa and has been shown to add valuable information. Although there is a correlation between the foci of activity and the areas of malignancy in the prostate gland, the clinical value of (18)F-FCH is still controversial for detection of the malignant focus in the prostate. For the T-staging of PCa at diagnosis the value of (18)F-FCH is limited. This is probably due to limited resolution of PET system and positive findings in benign prostate diseases. Conversely, (18)F-FCH PET/CT is a promising imaging modality for the delineation of local and distant nodal recurrence and bone metastases and is poised to have an impact on therapy management. In this review, recent studies of (18)F-FCH PET/CT in PCa are summarized.
