Dynamic contrast enhancement in prostate MRI as predictor of erectile function and recovery after radical prostatectomy.

Purpose: To analyze routine preoperative prostate MRI to predict erectile function (EF) before and after radical prostatectomy (RP).

Methods: Patients who underwent RP with an existing preoperative MRI including dynamic contrast-enhanced images and completed International Index of Erectile Function (IIEF-5) questionnaires at baseline and 12 months postoperative. They were divided into four erectile dysfunction (ED) groups according to preoperative IIEF-5 score.
