Research Abstract |
Regional myocardial rotational motion analyzed with cine MRI by following up the track of characteristic points on the intimal or the epicardial surface of left ventricle was almost equivalent to that with myocardial tagging images by following up the track of the intersections of grid-like tags on the left ventricular myocardium. Angle of rotation or migration length on the approximated circle of the left ventricle in each successive images should be used for the regional myocardial rotational motion analysis. Some estimate methods of appropriate contrast injection rate and acquisition start timing forcardiac MDCT could be proposed.
