Frequently, these clinical scenarios involve an older patient with comorbidities and a small renal mass (4 cm). (, CT in a 57-year-old woman with a renal AML.

Prednisone: 50 mg PO (three doses total) to be taken 13 hours, 7 hours and 1 hour prior to appointment. Minimize SENSE if there is mottling in the center of the image. Computed tomography (CT) and MR imaging are mainstays for renal mass characterization, presurgical planning of renal tumors, and surveillance after surgery or systemic therapy for advanced renal cell carcinomas. Plan the axial slices on the coronal plane; angle the position block parallel to the right and left renal pelvis. In order to optimally visualize the small foci of fat, thin sections (eg, 1.25mm) may be required.
