摘　　要：目的评价3D MIA DICOM数据分析软件对心腔容积定量评估的准确性。材料与方法对10个新鲜猪心和10例经心脏超声检查后的住院患者行64排螺旋CT心脏扫描,采用3D MIA DICOM数据分析软件分析并测量猪心的右心室容积和患者左室心腔容积,分析3D MIA DICOM数据分析软件测量值与猪心实际容积和人体心脏超声测量值之间的相关性。结果3D MIA DICOM软件所测猪心的右室容积和人体心脏舒张末期左室容积与物理测量值及心脏超声测量值之间具有很好的相关性(r1=0.94,r2=0.97),Altman and Bland一致性分析表明二者具有高度的一致性。结论3D MIA DICOM数据分析软件为定量分析心腔容积提供了一种无创、简单可行且准确可信的新方法。Objective To explore the accuracy of measuring ventricular volume by the 3D MIA DICOM data analysis software. Materials and Methods 10 pig＇s fresh hearts and 10 patients who accepted RT-3DE were examined by 64 slices CT. The right ventricular volume of the pig＇s hearts and the left ventricular volume of 10 patients were measured by 3D MIA DICOM data analysis software, and correlation the practical right ventricular volume of the pig＇s hearts with practical left ventricular volume of 10 patients were analyzed. Results The correlation between the measured values and the results of practical ventricular volume were better correlated （r1= 0. 94, r2 = 0.97 ,respectively）. Significant difference was not found between them（P 〉 0.05）. Conclusion 3DMIA DICOM data analysis soft is a more accurate,convenienve and exact method in measuring ventrieular volume.
