Radiomics-Based Classification of Patients with Repaired Tetralogy of Fallot by Cardiac Magnetic Resonance

Radiomics is a novel technique of advanced cardiac magnetic resonance (CMR) phenotyping by analyzing a couple of variables of cardiac shape and tissue texture. This study aimed to develop the radiomics-based classification model to differentiate rTOF patients from normal controls and evaluate the representative features of ventricular and myocardial abnormalities in rTOF patients. In conclusion, the radiomics-based classification model can successfully differentiate rTOF patients from normal controls with routine CMR cine images. The selected features underlined the right ventricular remodeling and left ventricular myocardium fibrosis in rTOF patients.
