Figure 11c.
Renal cell carcinoma in a 54-year-old woman. (a) Fast spin-echo T2-weighted MR image shows a mass (arrow) that arises from the left kidney. The mass demonstrates intermediate signal intensity, a finding that is consistent with a solid mass or hemorrhagic cyst. (b) Axial diffusion-weighted image (b = 500 sec/mm2) shows the mass with high signal intensity (arrow). (c) On an axial ADC map, the mass (arrow) demonstrates low signal intensity (restricted diffusion), a finding that is consistent with a solid tumor.
