Blood pool agent
WebThe inherent contrast between blood and myocardium with MRI depends largely on the proton concentration and longitudinal (T 1) and transverse (T 2) relaxation times. The use of MRI contrast agents or different pulse sequences can modulate this inherent contrast. 1 Most of the current applications for cardiovascular magnetic resonance (CMR) use ...

WebBlood pool agents (intravascular contrast agents) remain in the blood for a prolonged time compared with conventional contrast agents, which diffuse quickly into the interstitial … WebAfter intravenous injection, ferumoxytol has a long intravascular half-life (~14.5 hrs) and initially behaves as a blood-pool agent. (Interestingly, ferumoxytol was originally developed by AMAG Pharmaceuticals as an intravascular MR contrast agent, but the company instead decided to market it for treatment of anemia!)
WebNational Center for Biotechnology Information WebBlood Pool Agents Blood pool agents ( intravascular contrast agents) remain in the blood for a prolonged time compared with conventional contrast agents, which diffuse quickly into the interstitial space. Magnetic resonance angiography ( MRA ), cardiovascular imaging, or contrast enhanced MRIs are possible over an hour or more.
WebThe use of blood pool agents has further facilitated the use of MR angiography (MRA); their high molecular weight allows for lower doses of contrast medium administration …
Blood pool agents (BPAs) are a class of magnetic resonance angiography contrast agents. Blood pool agents (also known as intravascular contrast agents) are differentiated from other contrast agents due to their high molecular weight and higher relaxivities. Their large size prevents diffusion through the … See more Due to their extended time in the circulatory system, blood pool agents can be used for delayed steady-state imaging, and additionally these results can be combined with first pass arterial imaging.
