Purpose or Case Report: MR Urography is an advanced imaging technique with increasing utilization that allows the interpretation of both anatomic and functional urologic data. This allows for a more efficient study of renal parenchymal and collecting system abnormalities, however the complexity and volume of functional data can make for an intimidating task to the interpreting radiologist. Key factors to success include: adequate patient preparation, optimal imaging protocol in conjunction with sedation/anesthesia and complex advanced post-processing techniques.

In this educational poster, we aim to provide an initial overview of MRU with practical points on appropriate patient preparation and study optimization, followed by a detailed overview of the myriad of functional data acquired with each study. Finally, we will review a series of image-rich cases along with the post-processed functional data in order to illustrate the approach to interpretation in the setting of anatomic abnormalities on MRU.
