Magnetic resonance imaging contrast media
What are Magnetic resonance imaging contrast media?
Substances used in magnetic resonance imaging (MRI) to improve the visibility of internal body structures. In magnetic resonance imaging, contrast media are chosen for their paramagnetic property, which shortens relaxation time.
The contrast material used in MRI (Magnetic Resonance Imaging) called gadolinium is less likely to produce an allergic reaction than the iodine-based materials used for x-rays and CT scanning. Very rarely, patients are allergic to gadolinium-based contrast materials and experience hives and itchy eyes.
MRI contrast agents are a unique class of pharmaceuticals that enhance the image contrast between normal and diseased tissue and indicate the status of organ function or blood flow after administration by increasing the relaxation rates of water protons in tissue in which the agent accumulates.
Gadopentetate injection is a magnetic resonance imaging (MRI) contrast agent that is used to help create a clear picture of the body during an MRI scan. MRI scans are a special kind of diagnostic procedure that use magnets and computers to create images or “pictures” of certain areas inside the body.
In general, T1- and T2-weighted images can be easily differentiated by looking the CSF. CSF is dark on T1-weighted imaging and bright on T2-weighted imaging. A third commonly used sequence is the Fluid Attenuated Inversion Recovery (Flair).
