[Diffusion-weighted imaging for prostate cancer localization: comparison of apparent diffusion coefficient values in cancerous and non-cancerous tissues, and the Gleason score of the radical prostatectomy specimens].

Purpose: We compared magnetic resonance imaging (MRI) with radical prostatectomy specimens to evaluate the diagnostic performance of diffusion-weighted imaging (DWI) and the apparent diffusion coefficient (ADC) value for prostate cancer localization.

Materials And Methods: We performed a retrospective study of 44 patients who underwent radical prostatectomy. We compared MRI with pathological specimens (74 tumors) to evaluate their diagnostic performance of cancer localization.
