摘　　要：目的:应用声学组织灰阶定量技术,研究扩张型心肌病人的心肌组织灰阶特征。方法:应用计算机软件对正常人42例和经临床确诊的扩张型心肌病患者30例进行图象分析。结果:病例组一尖瓣水平的短轴切面上,室间隔和左室侧壁的心肌灰阶值均高于正常人,均有显著差别(P<0.01),而前壁的心肌灰阶值均低于正常人,有显著差别(P<0.01)。在乳头肌水平的短轴切面上,病例组室间隔和左室侧壁的心肌灰阶值稍高于正常人,但无显著差别(p>0.05),而前壁和后壁心肌灰阶值均低于正常人,均有显著差别(P<0.01)。Objective: To observe tissue characterization of the dilatied cardlomyopathy (DCM), we measured the gray-scale of the different region of left ventricle of DCM with computer-assistant quantitative analysis of myocardial echodensity. Methods: Thirty patients with DCM and fourty-two normal subjects were selected and analyzed by Adobe Photoshop 6.0 software. Results: The gray-scales of the interventricular septum and left ventricular lateral wall at the mitral level were higher than normal subjects (P<0. 01 ) . but the gray-scales of left ventricular anterior wall was less than normal subjects ( P<0.01). The gray scales of left ventricular anterior wall and posterior wall at the papillary level were less than normal subjects ( P<0.01 ). Conclusion:The distribution of myocardial echodensity in the patients with DCM were not uniform. The gray scale of the interventricular septum and left ventricular lateral wall at the mitral level were higher than normal, but the gray scale of left ventricular anterior wall and posterior wall at the papillary level were less than normal subjects.
