摘　　要：目的应用实时三维超声心动图(RT-3DE)和640层CT(640-MSCT)定量评价左心室容积和收缩功能,探讨两种方法测值的相关性及在左心功能评价中的应用价值。方法选择临床或冠状动脉造影确诊为冠心病的患者42例,分别行RT-3DE和640-MSCT心脏增强(分别采用自动法和手动法)检查,测量指标包括:左心室舒张末期容积(LVEDV)、左心室收缩末期容积(LVESV)、左心室每搏输出量(LVSV)和左心室射血分数(LVEF)。将两种方法各测量值的结果进行比较。结果(1)RT-3DE测得左心容积及功能指标与640-MSCT(自动、手动两种方法 )测值(LVEDV、LVESV、LVSV及LVEF)间相关性较好(P<0.01);(2)640-MSCT与RT-3DE左心室容积与心功能测值之间差别在于:LVEDV、LVESV两项指标640-MSCT测值均高于RT-3DE测值(P<0 05),LVSV值640-MSCT测值稍高于RT-3DE测值(P>0.05),而LVEF值640-MSCT测值稍低于RT-3DE测值(P>0.05)。结论 640-MSCT与RT-3DE在评价冠心病患者左心容积及功能方面高度相关,RT-3DE可推荐为临床首选影像学检查;根据不同患者的病情和各自特点,将640-MSCT与RT-3DE结合使用,可提高临床的影像学诊断率,为临床提供更多的诊疗信息。Objective To compare the real- time three- dimensional echography（RT- 3DE） and 640- slice CT （640- MSCT） in quantitative assessment of left ventricular volume and systolic function in patients with coronary heart disease. Methods Forty two patients with coronary heart disease confirmed clinical y and/or by coronary angiography were enrol ed in this study. Left ventricular volume and cardiac function, including EDV, ESV, SV, EF%were assessed by 640- MSCT （using both automatic and manual method） and RT- 3DE ful- volume image technology, respectively. The results obtained from two techniques were com-pared. Results There were no significant differences in left ventricular volume and cardiac function indicators obtained from 640- MSCT manual method and those from automatic method （P〉0.05） . General y, the results obtained from RT- 3DE were con-sistent with those obtained from 640- MSCT, except that the values of EDV and ESV measured by 640- MSCT were higher than those by RT- 3DE （P〈0.05）. Conclusion The left ventricular volume and function measured with 640- MSCT and RT- 3DE were highly consistent with each other. RT- 3DE can be recommended as the first choice of imaging examination in patients with coro-nary heart disease.
