MR imaging of renal neoplasms.

MR imaging has many advantages over other modalities in the detection and staging of renal neoplasms, because of its intrinsic high soft tissue contrast, direct multiplanar imaging capabilities, and the availability of a non-nephrotoxic, renally excreted contrast agent. The ongoing refinement of breath-hold imaging sequences will probably broaden the use of MR techniques in imaging renal neoplasms.
