Cine tagged images and their evaluation. a End-diastolic and end-systolic images of cine tagging series in mid-ventricular short-axis and 4-chamber orientations. Yellow grid lines detected by the evaluation software are overlaid. b Derived time courses of LV myocardial radial (RR, red line), circumferential (CC, blue line) and longitudinal (LL, green line) strains and of LV myocardial torsion (gray line). Extrema of curves are annotated. c Derived time courses of LV myocardial radial (RR, red line), circumferential (CC, blue line) and longitudinal (LL, green line) strain rates and of LV myocardial torsion rate (gray line). Systolic and early diastolic extrema of curves are annotated. ED = time of LV end-diastole; ES = time of LV end-systole
