Examples of the protocol for a healthy control (top) and patient with severe DCM (bottom). Top: A 52 year-old healthy male control with a normal sized left ventricle (end-diastolic diameter 5.6 cm) and preserved left ventricular ejection fraction (57.8%) (A). Septal T2 was 51.6 ms (B), septal native T1 924.9 ms (C) and there was no LGE (D) or significant diffuse fibrosis (post-contrast T1 467.1 ms, ECV 27%, E). GCS was -15.68% (F). Bottom: A 58 year-old severe DCM patient with a dilated left ventricle (end-diastolic diameter 8.0 cm) and severely impaired left ventricular ejection fraction (28.4%) (G). Septal T2 was 59.8 ms (H), septal native T1 1017.8 ms (I). There was midwall LGE (J; arrow) also reflected by the reduced post-contrast T1 and ECV (post-contrast T1 429.8 ms, ECV 35%, I; arrow). GCS was -5.15% (K).
