MRI techniques using presaturation tagging and velocity-encoded phase maps combined with breath-hold scanning enable simple, reproducible quantification of regional heart wall motion abnormalities.
This review highlights the utility of MRI techniques, such as presaturation tagging and velocity-encoded phase maps combined with breath-hold scanning, for quantifying myocardial wall motion abnormalities.
Methods for the noninvasive measurement of three-dimensional myocardial motion with MRI have recently been developed using presaturation tagging and velocity-encoded phase maps. The quality of clinical cardiac MRI studies has also recently improved with the advent of breath-hold scanning. The combination of breath-hold imaging with tagging and velocity-encoding sequences has made the measurement of myocardial wall motion in patients a simple and reproducible exam. These methods make it possible to quantify the severity and extent of regional heart wall motion abnormalities both at rest and during stress. This article reviews the MRI techniques developed for these applications.
Elliot R. McVeigh (1996) conducted a review in Myocardial wall motion abnormalities. MRI motion tracking techniques (presaturation tagging and velocity-encoded phase maps) was evaluated. MRI techniques using presaturation tagging and velocity-encoded phase maps combined with breath-hold scanning enable simple, reproducible quantification of regional heart wall motion abnormalities.
