Examples of images by tagging (a), displacement encoding with stimulated echoes (DENSE) (b) and feature tracking (c) analysis with corresponding contour overlay in left ventricular short axis and 4-chamber views. In tagging, the endocardial and epicardial borders are marked by yellow and green contours, respectively. In DENSE, the images are shown in diastole with points on myocardium depicting the 2D displacement field. In feature tracking, the endocardial and epicardial borders are marked by red and green contours, respectively with myocardium marked in yellow
