Overview
MRI may be helpful in the diagnosis of bladder cancer.
MRI
- Abdominal and pelvic MRI may be helpful in the diagnosis of bladder cancer. Findings on MRI suggestive of bladder cancer include:[1][2][3][4][5][6]
- T1: isointense compared to muscle
- T2: slightly hyperintense compared to muscle
- T1 weighted image with gadolinium contrast: demonstrates enhancement
- Detect superficial and multiple tumors
- Extravesical tumor extension
- Surrounding organ invasion
