Schematic diagram of partial parameter measurement of CMR. a End-diastolic phase of the 4-chamber cine image, line 1 measured the thickness of the noncompacted myocardium, line 2 measured the thickness of the compacted myocardium, line 3 (from mitral orifice to apex) measured the length of the long axis of the left ventricle; b LGE-, the red circle represented the endocardial boundarie, green circle represented the epicardial boundarie and the blue circle represented the normal myocardium; c LGE +, the yellow blocks represented areas of LGE identified by the software; d AHA 17 segment model distributions of LGE
