【摘要】：目的对比分析全自动容积成像系统与二维超声对瘢痕子宫前壁下段厚度的测量价值。方法两位医师分别使用常规二维超声探头和全自动容积成像系统独立测量200例晚孕期瘢痕子宫前壁下段厚度3次,统计每位医师3次测量组内相关系数和两位医师之间Kappa系数和组间相关系数,及Bland-Altman散点图。结果全自动容积成像系统测量的组内相关系数均0.96、两位医师的Kappa系数为0.95、组间相关系数为0.98、BlandAltman散点图测值差异的95%一致性界限从-0.30~0.30;二维超声对应组内相关系数均0.96、Kappa系数为0.65、组间相关系数0.80、测值差异的95%一致性界限从-0.69~0.71。结论全自动容积成像系统提高了瘢痕子宫前壁下段厚度测量的准确率,值得在临床中应用和推广。
[Abstract]:Objective to compare and analyze the value of automatic volume imaging system and two-dimensional ultrasound in measuring the thickness of anterior and inferior segment of scar uterus. Methods the thickness of anterior and inferior segment of scar uterus in 200 cases of late pregnancy was measured by conventional two-dimensional ultrasound probe and automatic volume imaging system respectively. The intra-group correlation coefficient, the Kappa coefficient and the inter-group correlation coefficient between two physicians were measured three times per physician, and the Bland-Altman scatter diagram was used. Results the intra-group correlation coefficient measured by automatic volume imaging system was 0.96, the Kappa coefficient of two physicians was 0.95, and the correlation coefficient was 0.98. The 95% consistency limit of Bland Altman scatter plot was from-0.30 to 0.30. The intra-group correlation coefficient was 0.96, the Kappa coefficient was 0.65, and the correlation coefficient was 0.80. The 95% consistency limit of the difference between the two-dimensional ultrasound group was from-0.69 to 0.71. Conclusion the automatic volume imaging system can improve the accuracy of the thickness measurement of the anterior and inferior segment of the scar uterus, which is worthy of clinical application and popularization.
