There have been no reports of major studies to the utility of DLR for DWI with high b values for improving image quality and detection performance for patients with prostatic cancers. We hypothesized that DLR could improve image quality and diagnostic performance of DWI with high values, and that an appropriate b value might be determined for this setting. The purpose of this study was thus to determine the utility of the DLR method for DWI and the appropriate b value for detecting prostatic cancer using a 3T MR system in routine clinical practice.
