Overview

Abdominal and pelvic MRI may be helpful in the diagnosis of urethral cancer. MRI may be superior to CT scan to detect superficial and multiple tumors, extraurethral tumor extension, and surrounding organ invasion.

MRI

• Abdominal and pelvic MRI may be helpful in the diagnosis of bladder cancer. Findings on MRI suggestive of urethral cancer include:
  • T1: isointense compared to muscle
  • T2: slightly hyperintense compared to muscle
  • T1 weighted image with gadolinium contrast: demonstrates enhancement
  • Detect superficial and multiple tumors
  • Extra Urethral tumor extension
  • Surrounding organ invasion
