“…There is an overlap of the different enhancement patterns making lesions with an initial steep slope and following plateau phase equivocal lesions (score 3) [27]. Reading prostate MR requires broad experience [28]. The utilization of a scoring system might help to enable a less experienced reader to correctly judge a lesion.…”

“…[6][7][8] However, the interpretation of multiparametric MRI remains difficult and with substantial interreader variability. 9 In 2012, the European Society of Urogenital Radiology (ESUR) proposed the Prostate Imaging Reporting and Data System (PI-RADS) 10 in an attempt to standardize scanning protocols and diagnostic criteria for multiparametric MRI. Various studies have evaluated this scoring system and suggested it improves imaging interpretation and diagnostic accuracy; [11][12][13] yet, changes were recommended to further enhance it.…”

Objective: To compare the diagnostic accuracies and interreader agreements of the Prostate Imaging Reporting and Data System (PI-RADS) v. 2 and University of California San Francisco (UCSF) multiparametric prostate MRI scale for diagnosing clinically significant prostate cancer. Methods: This institutional review board-approved retrospective study included 49 males who had 1.5 T endorectal MRI and prostatectomy. Two radiologists scored suspicious lesions on MRI using PI-RADS v. 2 and the UCSF scale. Percent agreement, 2 32 tables and the area under the receiver operating characteristic curves (Az) were used to assess and compare the individual and overall scores of these scales. Interreader agreements were estimated with kappa statistics. Conclusion: Although PI-RADS v. 2 DWI score may have a higher discriminatory performance than the UCSF scale counterpart to diagnose clinically significant cancer, the utilization of the UCSF scale weighing system for the integration of PI-RADS v. 2 individual parameter scores improved the accuracy its overall score. Advances in knowledge: PI-RADS v. 2 is moderately accurate for the identification of clinically significant prostate cancer, but the utilization of alternative approaches to derive the overall PI-RADS v. 2 score, including the one used by the UCSF system, may improve its diagnostic accuracy.

“…Prior publications have demonstrated significant inter-observer variability in prostate MRI interpretation, with varying levels of reader experience being a key contributor [52,53]. Formal education programs including individual feedback, case reviews, and follow-up of pathology results are of paramount importance in attaining expertise and maximizing one's diagnostic performance.…”

Implementation of Multi-parametric Prostate MRI in Clinical Practice

While initial implementations of prostate MRI suffered from suboptimal performance in tumor detection, technological advances over the past decade have allowed modern multi-parametric prostate MRI (mpMRI) to achieve high diagnostic accuracy for detection, localization, and staging and thereby impact patient management. A particular emerging application of mpMRI is in the pre-biopsy setting to allow for MRI-targeted biopsy, for instance, through real-time MRI/ultrasound fusion, which may help reduce the over-detection of low-risk disease and selectively detect clinically significant cancers, in comparison with use of standard systematic biopsy alone. mpMRI and MRI-targeted biopsy are spreading beyond the large academic centers to increasingly be adopted within small and community practices. Aims of this review article are to summarize the hardware and sequences used for performing mpMRI, explore patient specific technical considerations, delineate approaches for study interpretation and reporting [including the recent American College of Radiology Prostate Imaging Reporting and Data System (PI-RADS) version 2], and describe challenges and implications relating to the widespread clinical implementation of mpMRI.
