The tagging imaging on cardiovascular magnetic resonance evaluates the dynamic deformation of lines or grids superimposed on the myocardium during the cardiac cycle, and also provides the quantitative parameters as well as strain. The sensitivity and quantitative capability of tagging imaging for detecting the deformation of myocardium in ischemic heart disease had been reported. We hypothesized the feasibility of tagging imaging for detecting the details of myocardial dysfunction as well as dyssynchrony of idiopathic dilated cardiomyopathy (DCM). The purpose of this study was to evaluate the details of myocardial dysfunction in DCM patients using tagging imaging.
