[Abstract] Objective: To investigate the clinical value of magnetic resonance imaging (MRI) in the diagnosis of noncompaction of ventricular myocardium (NVM).Materials and Methods: We retrospectively analyzed the clinical manifestations and MRI findings of 10 NVM patients.Results: Ten patients (9 males and 1 female) presented with different clinical features. One patient was referred with no symptom, 9 patients with different degree of chest distress and palpitations, and the most serious manifestations happened in 1 adolescent with whole heart failure and thrombus in right subclavian vein, vena cava superior and left ventricular apex. Abnormal findings of electrocardiogram were found in 8 patients including hypertrophy (2 patients) and cardiac arrhythmia (6 patients). Noncompaction myocardium involved in left ventricular in 3 patients, right ventricular in 2 patients and biventricular in 5 patients. The most frequently involved segments were apex and the least determined segment were basal-septal. The ratio of thickness of the trabecular and compact layers were more easily identified by cine sequence in diastole and the slower flow in trabecular were more easily determined by Turbo spin echo sequence.Conclusion: Noncompaction of ventricular myocardium can be diagnosed accurately with cardiac MR multiple plane and sequences imaging.
