摘　　要：目的:利用体外猪心,检测新的实时三维超声心动图多平面成像技术测量左室容积的准确性。方法:应用4%多聚甲醛溶液固定15个体外猪心,将其浸入水槽中,应用GE Vivid7Di mension实时三维超声心动图三平面成像技术测量其左室容积,并与其左室注入水的真实容积进行对比。结果:直线相关性分析及配对t检验表明:实时三维超声心动图所测左室容积与其注入水后真实容积相关性好(r=0·94),两者间差异无统计学意义。Alt man and Bland一致性分析表明两者所测容积具有较高的一致性。结论:新的实时三维超声心动图多平面成像技术能够快速、准确地测量左室容积,从而可以提高对左心功能测量的准确性。Objective： Anatomic accurate model of left ventricle （LV） was developed. We sought to evaluate the accuracy of the new technique： real-time three-dimensional echocardiography （RT3DE） multi-plane imaging for quantifying the LV volumes in vitro experiment studies. Method： Fifteen freshly exercised porcine hearts were first soaked in 10% formaldehyde solution for fixing the shape of the left ventricle cavities. RT3DE multi-plane imaging technique was then performed with the models placed in a water tank, every model＇s volume of left ventricle was measured on-line. And the results were compared with the actual volumes verified by water displacement, which served as a reference standard. Result： The correlation analysis and paired sample test demonstrated that there was a good correlation and no significant difference between the RT3DE results and the actual volumes. It also shows good agreement between the two methods according to the technique of Bland and Altman. Conclusion： The new RT3DE multi-plane imaging technique can quantify LV volumes accurately and rapidly, which can also promote the accuracy of LV function.
