磁共振成像对肥厚性心肌病的诊断价值

Diagnostic Value of MRI in Evaluating Hypertrophic Cardiomyopathy

目的 探讨磁共振对肥厚型心肌病(hypertrophic cardiomyopathy,HCM)的临床应用价值。方法 对4例经 病史、临床表现、心电图及超声心动图检查(ultrasound cardiogram,UCG)诊断为HCM的患者,进行MRI检查,采用 MASS专用心功能分析软件计算左室心肌质量、左室舒张、收缩末期容积和射血分数等参数。比较UCG和MRI诊 断HCM的作用。结果 MRI和UCG在检测左心室心肌质量、左室舒张、收缩末期容积及射血分数时,两者结果一 致。结论 MRI能较全面的了解心脏的解剖和功能,对诊断HCM有重要的临床应用价值。

Objective To investigate the clinical value of MRI in evaluating hypertrophic cardiomyopathy（HCM）. Methods Four cases of HCM verified by history, clinical presentation, electrocardiogram and ultrasound cardiogram （UCG） were performed by technique of MRI. Some indexes for evaluating cardiac function were measured by using MASS auto-quantitative program. In the study, MRI and UCG as imaging cardiac structures and function were studied and compared. Results There was no significant difference between MRI and UCG in examining myocardium, end-diastolic volume, ejection fraction of left ventricle. Conclusion MRI can fully provide the information of cardiac anatomy and function, it is of great value in clinical application.
