Myocardial twist and torsion as a function of cardiac phase measured by 3D cine DENSE in seven mice. Myocardial twist and torsion as a function of cardiac phase measured by 3D cine DENSE in seven mice. In (A), twist angle as a function of cardiac phase is shown for basal, mid-ventricular, and apical locations. In (B), LV torsion, which is the normalized gradient of twist in the longitudinal direction, is plotted. Data are plotted as mean ± standard error.
