WebConclusions: Gadofluorine-M-enhanced MRI is effective for in vivo detection of atherosclerotic plaque inflammation and neovascularization in an animal model of atherosclerosis. These findings suggest that gadofluorine-M enhancement reflects the presence of high-risk plaque features believed to be associated with plaque rupture. WebMuthurangu et al. 140 demonstrated that phase-contrast MRI accurately quantifies PVR, even in patients with high pulmonary blood flow and with varying amounts of oxygen and nitric oxide therapy.

WebAn MRI contrast agent is a special dye used to improve the visibility of certain tissues on an MRI scan. If your doctor recommends that you have an MRI scan with a contrast agent, the agent will usually be injected into a vein in your body. The most common MRI contrast agents contain gadolinium and have been in use since 1983. WebHigh magnetic field ( B0) is one such option, representing the ultimate limit of the SNR of images. The SNR is directly proportional to B0 and is the primary determinant of the image resolution. 15,16 HF MRI is also critically dependent on RF coil technology and gradient design.
