目的:评价电子束CT对原发性扩张型心肌病诊断及鉴别诊断的价值。材料与方法:对9例经临床及影象学诊断的扩张型心肌病患者行电子束CT扫描。结果:左心室扩张8例,均有室壁运动普遍减弱,LVEDV235±103ml,LVEF20.3％±7.3％;右心室扩张伴运动减弱1例。结论:电子束CT能全面反映扩张型心肌病的病理及功能改变,可作为扩张型心肌病诊断的手段。
Objective: To evaluate the value of electron beam CT in the diagnosis and differential diagnosis of primary dilated cardiomyopathy. Materials and Methods: Electron beam computed tomography (CT) was performed in 9 patients with dilated cardiomyopathy diagnosed clinically and radiologically. Results: Left ventricular dilatation in 8 cases, wall motion were generally weakened LVEDV235 ± 103ml, LVEF20.3% ± 7.3%; right ventricular dilatation with weakening in 1 case. Conclusion: Electron beam CT can fully reflect the pathological and functional changes of dilated cardiomyopathy and can be used as a diagnostic tool for dilated cardiomyopathy.
