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. Findings on MRI scan suggestive of prostate cancer listed below:
- T2
- DWI
- Often shows restricted diffusion
- Dynamic contrast enhancement (DCE)
- Shows enhancement - but it can be difficult to distinguish from prostatitis or benign prostatic hyperplasia (especially in the central zone lesions)
- More specific than T2 signal
