WebGadolinium-based Blood Pool Agents. At present there is only one Gd-based blood pool agent approved for clinical use: gadofosfosveset trisodium (Vasovist ®, Schering, Berlin). It is a non-specific CA of low molecular weight (975, 88 Dalton (Da)) that is retained in the blood pool due to a non-covalent binding to serum albumin. WebABLAVAR™ (formerly named Vasovist™) is a blood pool agent for magnetic resonance angiography (), which opens new medical imaging possibilities in the evaluation of aortoiliac occlusive disease (AIOD) in patients with suspected peripheral vascular disease. ABLAVAR™ binds reversibly to blood albumin, providing imaging with high spatial …

WebSep 21, 2016 · MRI contrast agents may be administered orally or intravenously. According to biodistribution and applications, MRI contrast agents may be categorised into three types: extracellular fluid, blood pool and target/organ-specific agents. A number of contrast agents have been developed to selectively distinguish liver pathologies. WebNeuroimaging studies have identified that ferumoxytol, an iron oxide nanoparticle blood pool agent, appears to be a superior contrast agent to accurately assess therapy-induced changes in brain tumor vasculature, in brain tumor response to therapy, and in differentiating central nervous system lesions with inflammatory components.
WebGadofosveset has been the first blood pool MRI contrast agent to become commercially available and received approval by the U.S. Food and Drug Administration in 2008 for imaging of aortoiliac occlusive disease in adults (≥18 years) with known or suspected peripheral vascular disease.
WebThe blood pool contrast agent that we used was Ferumoxytol. This agent consists of an ultrasmall (∼30 nm) superparamagnetic iron oxide core encapsulated in semisynthetic carbohydrate.
