1. A method of detecting regions of blood flow abnormality or variation in a human or non-human body, said method comprising the steps of (1) administering into the cardiovascular system of said body a contrast enhancing amount of a paramagnetic metal containing magnetic resonance imaging contrast agent, (2) subjecting said body to a magnetic resonance imaging procedure and obtaining a series of temporally spaced magnetic resonance signals or images from regions in at least a part of said body into which said agent passes, (3) detecting temporal variations in said signals or images, and (4) identifying from said temporal variations in said signals or images regions of abnormal or modified blood flow in said body and providing a quantitative indication of the degree of blood flow abnormality or modification therein.
