Prostate Magnetic Resonance Imaging Interpretation Varies Substantially Across Radiologists

Abstract: We evaluated the interpretation of multiparametric magnetic resonance imaging of the prostate in routine clinical care. Diagnostic accuracy depends on the Prostate Imaging Reporting and Data System score and the radiologist.

“…If slightly different criteria suggested by other authors were applied to our cohort (i.e., PIRADS = 3 and PSAD < 0.15) [14,16,17], it would result in a 50% reduction in the number of biopsies but would also miss 21% of significant cancers. We speculate that the discrepancy between this finding and those reported in other papers might be explained by the performance of the mpMRI [3,18,19]. This study has some limitations.…”

“…However, PSA screening leads to over-diagnosis, which leads to unnecessary expensive and painful needle biopsies and potential over-treatment 2 . Multiparametric MRI which relies heavily on diffusionweighted imaging (DWI) has been increasingly becoming the standard of care for prostate cancer diagnosis in radiology setting where the area under the receiver operating characteristic curve (ROC) varies from 0.69 to 0.81 for radiologists detecting PCa 3 . A standardized approach to image interpretation called Pi-Rads v2 4 has been developed for radiologists, however, there remain issues with inter-observer variability in the use of the Pi-Rads scheme 5 .…”

“…Multiparametric magnetic resonance imaging (MP‐MRI) has been developed as a triage tool to reduce the rates of negative biopsy and its use has become increasingly widespread since its validation 7 . However, MP‐MRI is relatively expensive and has shown a high rate of interoperator and intermachine variability, leading to MP‐MRI missing up to 28% of clinically significant diseases in practice 4,8‐10 …”

“…7 However, MP-MRI is relatively expensive and has shown a high rate of interoperator and intermachine variability, leading to MP-MRI missing up to 28% of clinically significant diseases in practice. 4,[8][9][10] The interconnected nature of the male urological system makes it an ideal candidate for liquid biopsy and noninvasive biomarkers for prostate cancer. There is a sizeable interest in the development of such noninvasive tests and classifiers capable of reducing the rates of initial biopsy in men while retaining the sensitivity to detect aggressive disease.…”
