This educational exhibit aims to highlight the role of MR Urography (MRU) in the setting of the pediatric patient with urinary outflow tract obstruction. This review encompasses the unique physiology of glomerular filtration in compensated vs decompensated uropathy and demonstrates the MR correlate to nuclear medicine. Read More

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.

Idiopathic thickening of the pyloric muscle can occur in young infants, causing projectile vomiting, electrolyte abnormalities, and necessity for surgical intervention to relieve the gastric outlet obstruction. Case reports have been published describing infants with HPS who also have portal venous gas (PVG) visualized within the liver. The presence of PVG in other clinical scenarios often indicates a severe and potentially life threatening bowel condition. The purpose of this study was to determine the incidence of infants with hypertrophic pyloric stenosis (HPS) and concurrent portal venous gas (PVG), as well as whether there are unique clinical features or different outcomes in the HPS patients with PVG versus without PVG.
