High contrast mri
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. WebSeveral MRI methods have been proposed to measure WEX BBB, but evidence remains scarce whether different methods can produce comparable WEX BBB. Purpose. To …
