Methods for noninvasive tissue tracking and quantification of myocardial shortening with magnetic resonance imaging have been developed using preparation tagging and velocity encoded phase maps. The concurrent development of rapid scanning techniques, such that a complete cine loop of a slice can be obtained in a breath-hold, has made the measurement of myocardial wall motion in patients a simple and reproducible examination. These methods make it possible to quantify the severity and extent of regional heart wall motion abnormalities both at rest and during stress.
