ABSTRACT

INTRODUCTION: Diagnosis, localization of recurrence in the management of prostate cancer patients with increasing concentrations of tumor serum markers is crucial for treatment planning of the patients. The present review describes the role of prostate MRI and (18) Fcholine PET/computed tomography (CT) in tumor detection and extent, when there is a suspicion of residual or recurrent disease after treatment of prostate cancer. METHOD: A systematic review of the literature was performed by searching in the PUB MED/MEDLINE database searching for articles in French or English published between the last 12years. RESULTS: In patient with a clinical suspicion of recurrence after treatment for prostate cancer, imaging can be used to distinguish between local recurrence and metastatic disease. (11)C-choline PET/CT and pelvic multiparametric MR imaging (mp MRI) are complementary in this indication. In this paper, the current status of imaging techniques used for the staging of patients with suspected locally recurrent or metastatic disease in patients treated for prostate cancer were reviewed. CONCLUSION: Mp MRI of the prostate may be valuable imaging modality for the detection and localization of local recurrence. C-choline PET/CT offers an advantage in detecting metastatic disease to lymph node and bone.
