摘要

MR angiography with ferumoxytol expands the toolset for imaging the pediatric abdominal vasculature. As an iron-based blood pool contrast agent, ferumoxytol allows for high-resolution imaging of the abdominal vessels that is not dependent on precise timing of contrast phases and can be used in patients with a contraindication to gadolinium-based contrast agents. At our institution, it has proven useful for abdominal indications including vascular mapping in the settings of portal hypertension, portosystemic shunts, and abdominal transplant evaluation, as well as for investigation of vascular malformations and vasculitis. Others have demonstrated its utility in tumor imaging, especially with hepatic tumors. In this review, we describe our protocol for ferumoxytol-enhanced MR angiography and discuss its various pediatric abdominal applications.
