Abstract

Computed diffusion-weighted magnetic resonance imaging (cDWI) is gradually being known to be useful to detect prostate cancer. We found that cDWIs (b=2000 s/mm2) were easily generated from measured DWIs (mDWIs) with image processing using Image J and that the contrast ratio (CR) of cDWIs-2000 appeared to be higher than the CR of mDWIs-1000 and mDWIs-2000. The diagnostic ability of cDWI-2000 for prostate cancer detection was equivalent to that of mDWI-2000. There is a possibility that cDWIs-2000 can replace mDWIs-2000.
