Diagnostic Accuracy of a MR Protocol Acquired with and without Endorectal Coil for Detection of Prostate Cancer: A Multicenter Study

INTRODUCTION: The purpose of this study was to compare diagnostic accuracy of a prostate multiparametric magnetic resonance imaging (mpMRI) protocol for detection of prostate cancer between images acquired with and without en-dorectal coil (ERC). MATERIALS: . Sensitivity and positive predictive value for detection of index lesions were assessed using 2 × 2 contingency tables. Differences between groups were tested using the McNemar test. Whole-mount histopathology served as reference standard. RESULTS: protocols, respectively. The differences were not statistically significant for R1 (p = 0.267) or R2 (p = 0.508). CONCLUSION: Our results suggest that there may be no significant differences for detection of prostate cancer between images acquired with and without an ERC.
