This study investigated the effectiveness of a low-dose (25% of a single treatment dose for anemia) ferumoxytol-infusion for vascular suppression in T2-weighted MR neurography of the brachial plexus. 3D STIR-FSE and 2D Dixon-FSE sequences of the brachial plexus were acquired in 12 healthy volunteers pre- and post-ferumoxytol. Quantitative and subjective assessments by two readers demonstrated superior vascular suppression and nerve visualization post-ferumoxytol without negatively affecting soft tissue contrast or fat suppression.
