Mark Evan Bittman MD, Abstract Co-Author: Nothing to Disclose

MR urography’s (MRU) ability to depict urinary tract morphology and renal function without ionizing radiation is a valuable tool in guiding diagnosis/management of pediatric urinary tract pathology, which traditionally requires multiple imaging modalities to evaluate MRU utilizes heavily T2-weighted and dynamic post contrast sequences which can rapidly define the anatomy and quantify renal enhancement and excretion Augmentation with hydration and diuretics is a useful tool to ensure uniform and timely contrast distribution for optimizing excretory phase imaging The pediatric population presents specific challenges for MRI, notably being patient cooperation and motion sensitivity often requiring sedation 

Discuss a spectrum of pediatric urinary tract anatomic abnormalities such as urinary tract obstruction, duplication anomalies, renal ectopia, ectopic ureters, primary megaureter, calyceal diverticulum, and ureteropelvic junction obstruction Appropriateness/indications of MRU in pediatric patients Discussion of MRU protocols, including patient preparation, sequence selection, and selection of contrast agents and diuretics Review of MRU clinical applications and discussion of benefits/advantages highlighting both the anatomic and functional information which influences clinical decision making
