The study is to determine clinical utility of T1rho to detect patients with cardiomyopathy. In the LGE positive group, the T1 mapping values and ECV values in the lesion area were significantly higher than those in the LGE negative group and the normal control group, while the T1rho values in the lesion area were significantly lower than those in the LGE negative and normal groups, and the display range of lesions was in good consistency with LGE and ECV. It can be used as an endogenous diagnostic index when myocardial structure changes.
