MRI is superior to other modalities in locally staging the tumor and is in some instances able to distinguish T1 from T2 tumors on T2 weighted image.^[1]

Transitional cell carcinomas are isointense to renal parenchyma on both T1 and T2 weighted images. Following administration of Gadolinium, TCCs enhance but less so than normal renal parenchyma.
T1 : Isointense to renal parenchyma
Moderate enhancement on gadolinium


Signal	Renal Pelvis	Ureter	Urinary Bladder

T1 Signal	Isointense to renal parenchyma	Isointense to muscle	Isointense to muscle
Isointense to muscle	Sessile or nodular tumors They grow deeper into the layers of the wall of the renal pelvis or ureter rather than into its cavity
