Synopsis

This clinically oriented talk will review the Renal Mass MRI technique/scanning protocols at NYU, review the basics in renal mass lesion subtyping and pitfalls in the characterization of renal lesions and the clinical impact therein.

Advances in the management of renal mass lesions (including surveillance imaging, partial/robotic nephrectomies and cryoablation techniques) have raised the threshold for expectations of radiology in the accuracy of our pre-operative predictions of renal pathology. Many of these predictions are thwarted by mixed tumor subtypes of renal lesions, and the phenomenon of aggressive translocation tumors occuring in younger and younger patients. However, a basic knowledge of the common renal tumor appearances which play by the rules is needed (ie, clear cell RCC with intravoxel fat, minimal fat AML, hypoenhancing papillary RCC), as well as a review of the ongoing challenges in renal MRI and how to overcome them (additive noise on subtraction images simulating enhancement, misregistration on subtraction images, edge artifact simulating loss of signal on opposed phase images, limitations and uses of diffusion). This clinically oriented talk will review the Renal Mass MRI technique/scanning protocols at NYU, review the basics in renal mass lesion subtyping and pitfalls in the characterization of renal lesions and the clinical impact therein.
