摘　　要：为了比较经胸一维(1D)，二维(2D) 和三维(3D) 超声心动图及核磁 共振方法 在扩张型心肌病患者左室心肌重量测定上的相关性，选择36例扩张型心肌病患者分别接受了 经胸常规（1D，2D）和3D超声心动图，以及心脏核磁共振（MRI）检查，并计算左室心肌重 量 。结果显示：1D数据与MRI测值相关性较低（r=0.42，P＞005）；而2D（r=0 .64，P ＜0.01）和3D超声测值（r=0.78，P＜0.01）与MRI值有较好的相关关系。与1D和 2D测 值比较，3D测值与MRI值有明显高的一致性（1D：399.2g；2D：285.9g；3D：172.6g比较MRI ： 199.1g）。三维超声的观察者间变异性为5.1%。提示经胸三维超声心动图方法可以较准确的 测定扩张型心肌病患者左室心肌重量，在临床上有较大的使用价值。This study was performed to compare left ventricular mass (LVM ) me asurement by one- (1D), two- (2D) and 3D echocardiography with magnetic resona nc e imaging (MRI) in patients with dilated cardiomyopathy (DCM). 36 patients with DCM underwent imaging by conventional 1D and 2D echocardiography as well as tran sthoracic 3D echocardiographic data acquisition. Also patients were imaged with cardiac MRI. LVM was determined. There was no significant correlation (r=0 .42，P＞0 05) for measuring LVM between 1D echocardiography and MRI in pati ents with DCM. A s ignificant correlation was obtained between 2D echocardiography and MRI (r=0 .64, P＜0.01) and between 3D and MRI (r=0.78, P＜0.01) in determination of LVM. Compared w ith 1D and 2D echocardiography, the 3D analysis achieved a significantly higher agreement with the MRI results (1D: 399.2 g, 2D: 285.9 g, 3D: 172. 6 g versus MR I: 199.1 g). Interobserver variability was 5.1% for measuring LVM by 3D echocard iography. These results suggest that LVM of patients with DCM can be accurately determined by transthoracic 3D echocardiography and this method could be used in clinical practice.
