Figure 6: 58-year-old patient with hematuria. Axial arterial phase contrast enhanced T1W MR image demonstrates a left sided enhancing lesion (black arrow) and a right sided unenhancing lesion (yellow arrow) (A); delayed phase contrast enhanced T1W MR image shows persistent enhancement of the left sided lesion (black arrow) consistent with bladder cancer; whereas the right sided lesion doesn’t not enhance which is consistent with blood clot (yellow arrow) (B).
