The purpose of this exhibit is: 1. To review the background on renal cell carcinoma (RCC) and mimics 2. To discuss the appropriate quantitative and qualitative MR protocols for characterization of T1a renal tumors including analysis of characteristic time-signal intensity curves 3. To review MR imaging characteristics of RCC subtypes and benign mimics (oncocytoma, minimal fat angiomyolipoma) on T1, T2, DWI, DCE and Arterial Spin Labelling 4. To describe the role of percutaneous renal biopsy and immunostains in guiding diagnosis among renal masses
