Over the last twenty years there has been a rapid expansion in the vast array of implantable cardiac devices utilized in pediatric patients. Imaging plays a key role in the management of patients with these devices. It is important for the pediatric radiologist to recognize the specific type of cardiac device visualized on radiographic images in order to make an accurate assessment of the appropriate position and any potential complications. With new cardiac devices entering the market it can be very perplexing and daunting for the radiologist to stay familiar with them all. We will seek to review old and new pediatric cardiac devices currently used at our institution and their radiographic appearance. These devices will be divided into categories of pacing devices, prosthetic heart valves, stents, closure devices, ventricular assist devices, extracorporeal membrane oxygenation systems (ECMO), and external monitoring devices. Pacing devices: a) Epicardial and transvenous pacing systems b) Leadless pacemakers Prosthetic heart valves: a) Surgically implanted valves b) Transcatheter valves Cardiac stents Closure devices: a) Patent ductus arteriosus closure device, b) Atrial septal defect closure device c) Vascular plugs and coils Ventricular assist devices: a) Left ventricular assist device, b) Right ventricular assist device, c) Bi-ventricular assist device Extracorporeal membrane oxygenation (ECMO) cannulas: a) Venous-arterial ECMO, b) Venous-venous ECMO External monitoring devices: a) Holter monitor, b) Loop recorder 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.
