We evaluated 47 patients suspected of having prostate cancers on synthetic DWI calculated from FOCUS DWI with PI-RADS version 2.0. Compared with conventional FOV DWI, FOCUS DWI is more useful for evaluation of prostate cancer with high spatial resolution and less distortion. S-DWI is able to enhance diagnostic ability of FOCUS without image degradation, which might be one of the best combinations, and contribute to the Prostate Imaging Reporting and Data System (PI-RADS) version 2.0.
