Left Ventricular Non-compaction (LVNC) manifesting with myocardial fibrosis can cause cardiac dysfunction, arrhythmia, and sudden death. Native T1 mapping is an emerging CMR technique in quantitative evaluation of myocardial fibrosis. This study aimes to investigate the usefulness of native T1 mapping in characterization of myocardial abnormalities in LVNC patients by comparing with late gadolinium enhancement. It may suggest that native T1 mapping may provide information for early detection of fibrosis in compacted myocardium and stratification of severity in Left Ventricular Non-compaction.
