Comparison of receiver-operating-characteristic curves in the test set. To discriminate late gadolinium enhancement on cardiac magnetic resonance in patients with hypertrophic cardiomyopathy (HCM), the reference model (green dotted line) and the combined model (red solid line) were developed. The reference model included family history of HCM, maximum left ventricular (LV) wall thickness, LV end-diastolic diameter on echocardiography, LV end-systolic volume, LV ejection fraction < 50%, left atrial diameter, and LV outflow tract pressure gradient at rest. The combined model was developed by combining the reference model and deep convolutional neural network-based probability.
