Blood pool agent
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. This thick coating prevents redistribution outside the vascular space. Blood elimination is via phagocytosis by macrophages in the reticuloendothelial system. WebBlood-pool agents (BPAs) are MRI contrast agents (CAs) characterized by their long circulation in the vascular system to provide an extended time window for high-resolution …
