Abstract
Characterization of myocardial stress and strain is necessary for a complete understanding of myocardial function. The precise quantification of regional myocardial strain is complicated by its time‐varying pattern and regional variation resulting from the anisotropy of the myocardium and by complex torsional and shortening motions of the heart during the cardiac cycle. The authors have developed a technique for point‐specific tracking of myocardial motion along all three axes in a constant selected section of myocardium by combining prospective section selection with in‐plane DANTE (delays alternating with nutations for tailored excitation) tissue tagging and phase‐contrast detection of motion perpendicular to the image plane. With this technique, it is possible to determine point‐specific myocardial strain values in vivo.
