The etiology of non⁃ischemic cardiomyopathy is complex, mainly resulting from heredity, myocardial metabolism, and myocardial structural change, rather than from coronary artery disease. Cardiac magnetic resonance (CMR) can display the characteristics of myocardial tissues at high resolution, and provide objective parameters of cardiac function. Traditional CMR image observation and analytic methods on the utilization of image are very limited, whereas radiomics technique based on CMR supplies a new approach for the research of non⁃ischemic cardiomyopathy. In this paper, research progress on application of radiomics based on CMR to non⁃ischemic cardiomyopathy is reviewed, mainly containing its application value in the diagnosis and prognostic prediction of hypertrophic cardiomyopathy, dilated cardiomyopathy, and cardiac amyloidosis.
