Abstract
6 patients with standard and segmented DWI presented with visible distortion of the posterior prostate boundary abutting the endorectal coil relative to T2w on standard, but not on segmented DWI. In 2 of 4 patients with posterior tumors abutting the prostate boundary, tumors were erroneously displaced outside of the prostate boundary in standard DWI, which was corrected using segmented DWI. Conclusions: Readout-segmented DWI improves the geometric performance of clinical endorectal coil prostate DWI at 3T, and should reduce uncertainties in tumor delineation for dose escalation.
