Use
Ferumoxsil is a turbid,slightly viscous, dark brown to orange-brown aqueous suspensionof silicone-coated, SPIO for oral administration.The suspension distributes to the stomach and small intestinewithin 30 to 45 minutes and passes distally to the largeintestine within 4 to 7 hours after ingestion. It is indicated toenhance the delineation of the bowel and to distinguish itfrom organs and tissues that are adjacent to the upper regionsof the GI tract. Its usefulness in the distal GI regionsis limited by transit time and dilution. Both T1- and T2-weighted images may be enhanced with ferumoxsil.
