Combined Whole Body and Multiparametric Prostate Magnetic Resonance Imaging as a 1-Step Approach to the Simultaneous Assessment of Local Recurrence and Metastatic Disease after Radical Prostatectomy

PURPOSE: We report our initial experience with whole body and dedicated prostate magnetic resonance imaging as a single examination to assess local recurrence and metastatic disease in patients with suspected recurrent prostate cancer after radical prostatectomy. MATERIALS AND METHODS: In this institutional review board approved, retrospective, single center study 76 consecutive patients with clinically suspected recurrent prostate cancer following radical prostatectomy underwent combined whole body and dedicated prostate magnetic resonance imaging at a single session from October 2014 to January 2016. Scans were evaluated to detect disease in the prostate bed and regional nodes, and at distant sites. Comparison was made to other imaging tests, and prostate bed, node and bone biopsies performed within 90 days. RESULTS: F-fluorodeoxyglucose positron emission tomography/computerized tomography and subsequent negative bone biopsy. CONCLUSIONS: Combined whole body and dedicated prostate magnetic resonance imaging is feasible in a clinical practice setting. It can provide incremental information compared to standard imaging in men with suspected prostate cancer recurrence after radical prostatectomy.
