Sometimes, a contrast medium may be used. A contrast medium is a substance, which helps obtain a better, sharper, clearer image of the scan. There are three ways in which it may enter the body, namely, rectal, oral and intravenously. In the technique of MRI, mostly, the substance used is Gadolinium. Due to Gadoliniums chemical properties, the water molecules relax which results in a better and more defined image, which helps get a better scan.
