Cardiovascular magnetic resonance (CMR) applications are evolving very rapidly. For the assessment of heart function, the interest has gone from pure volumetric analysis, where the only interest is tracking the inner surface of the heart chambers, to actual assessment of myocardium contractility, studying the deformation patterns of this complex muscular structure. A number of different CMR techniques have been developed for pursuing the goal of assessing the heart mechanics. All of these techniques, however, require specic acquisition procedures that add time to the overall CMR exam. This added exam time may limit the implementation of these techniques to specic cases where standard nontagged cine images cannot provide sufcient diagnostic information about myocardial contractility.
