Overview

MRI findings of transitional cell carcinoma of renal pelvis include isointense to renal parenchyma on T1 and T2, moderate enhancement on T1 contrast. MRI findings of transitional cell carcinoma of bladder and ureter include isotense to muscle on T1 signal, slightly hyperintense to muscle on T2 signal, and demonstrate enhancement on contrast MRI.

MRI

  • MRI is as reliable as CT for staging of invasive or locally advanced disease and may be better at evaluating tumors at the base and dome of the bladder.
  • Gadolinium-enhanced MRI may be superior to CT to detect superficial and multiple tumors, extravesical tumor extension, and surrounding organ invasion.[1][2]
  • MRI is useful for patients with contrast dye allergy
  • . Findings on MRI diagnostic of transitional cell carcinoma include:[3]
