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.
