Web8 de fev. de 2024 · The gadolinium ion is useful as an MRI contrast agent because it has seven unpaired electrons, which is the greatest number of unpaired electron spins possible for an atom. Gadolinium molecules shorten the spin-lattice relaxation time (T1) of voxels in which they are present. As a result, on T1-weighted images they have a brighter signal.

WebMRI uses a high-power magnet to temporarily change the position of hydrogen atoms that naturally exist within the body. This does not cause any long term changes in your body. As the hydrogen atoms return to their usual position, they emit different amounts of energy depending on the type of tissue they are in.

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.
