This article details indications, patient preparation, pulse sequences/protocols, and contrast agents for pediatric hepatobiliary MRI. When performed well, MRI provides superior diagnostic information relative to CT for evaluation of hepatic tumors, liver transplants, and biliary disease.
[Show abstract][Hide abstract] ABSTRACT: We present a pictorial essay on pediatric intestinal transplantation that describes the indications for pediatric intestinal transplantation, surgical technique, and the role of imaging in the pre-transplant work-up and detection of post-transplant complications. We illustrate the normal post-transplant imaging appearance and common complications, including rejection, infection, post-transplant lymphoproliferative disease (PTLD), mechanical dysfunction and vascular complications. We conclude with an imaging algorithm for suspected post-transplant complications based on clinical scenarios.
[Show abstract][Hide abstract] ABSTRACT: Gadoxetate disodium (Gd-EOB-DTPA) is a relatively new hepatobiliary MRI contrast agent. It is increasingly used in adults to characterize hepatic masses, but there is little published describing its use in children. The purpose of this paper is to describe our pediatric MRI protocol as well as the imaging appearance of pediatric liver lesions using gadoxetate disodium. As a hepatocyte-specific MRI contrast agent, Gd-EOB-DTPA has the potential to improve characterization and provide a more specific diagnosis of pediatric liver masses.
[Show abstract][Hide abstract] ABSTRACT: Gadoxetate disodium (Gd-EOB-DTPA) is a hepatobiliary MRI contrast agent widely used in adults for characterization of liver tumors and increasingly used in children. Hepatoblastoma is the most common primary hepatic malignancy of childhood. In this review, we describe our experience with this agent both before and after initiating therapy in children with hepatoblastoma.
