Figure 1

Short axis tagging at the mid ventricular level covering the cardiac cycle (A-F). Tagging is applied upon detection of QRS complex at end diastole (A). Tag lines follow the myocardial deformation during systole (B, C, and D) and relax in diastole (E, F). Fading of tag lines occurs near end diastole (F) due to T1 tissue relaxation.
