Active gastrointestinal hemorrhage identification by blood pool contrast-enhanced magnetic resonance angiography PEDIATRIC RADIOLOGY Williams, J., Vasanawala, S. S. 2011; 41 (9): 1198-1200


Localization of the source of gastrointestinal hemorrhage can be challenging. Currently, this is often accomplished with tagged red blood cell scintigraphy, with attendant ionizing radiation and relatively poor spatial resolution. We describe an analogous method of detecting acute gastrointestinal hemorrhage by enhanced MRI with blood pool contrast agent. Briefly, following precontrast fat-suppressed volumetric T1-weighted image acquisition, single-dose gadofosveset trisodium, a blood pool agent, is administered. Then serial post-T1-weighted images are obtained. This technique is a novel method for evaluating gastrointestinal hemorrhage.
