Overview

MRI may be helpful in the diagnosis of prostate cancer. On MRI scan, prostate cancer is characterized by a low signal within a normally high signal peripheral zone on T2-weighted images.

MRI

MRI may be helpful in the diagnosis of prostate cancer.[1] Findings on MRI scan suggestive of prostate cancer listed below:

  • T2
  • Using a endorectal coil, on T2-weighted images prostate cancer usually appears as a region of low signal within a normally high signal peripheral zone
  • Most significant cancers occur along the posterior portion of the gland abutting the rectum
  • DWI
  • Often shows restricted diffusion
  • Dynamic contrast enhancement (DCE)
