摘　　要：目的探讨自由解剖切面(OmniView)联合容积对比成像(VCI)在三维盆底超声中的应用价值以及OmniView-VCI技术与标准三维渲染技术测量盆腔裂孔面积的一致性并比较两种技术测量所需时间。方法选取2015年1~12月在湖北医药学院附属东风总医院超声科检查的231例女性受试者作为研究对象,其中112例未生育且无症状的女性受试者为对照组,108例盆底功能障碍女性受试者为实验组。首先获取每1例受试者的静态经会阴三维超声容积图像,通过OmniView-VCI分析每项三维数据以测量盆腔裂孔面积(由1名操作员测量两次,另1名操作员测量1次,目的在于评估观察者内及观察者间的可重复性)。进行2次测量的操作员随后使用三维渲染技术测量裂孔面积,以评估两种技术测量结果的一致性。通过同类相关系数评估OmniView-VCI技术的可重复性以及其与三维渲染技术测量结果的一致性。结果通过OmniView-VCI技术对裂孔面积进行测量,结果表明在两组中,OmniView-VCI技术均有较高的观察者内及观察者间可重复性,并且,两组中OmniView-VCI技术与三维渲染技术的测量结果有较高的一致性;对两组的可靠性分析未发现系统性差异(P>0.05);两组就计算盆腔裂孔面积而言,OmniView-VCI技术所使用的时间均明显比标准三维渲染技术所使用的时间短(P<0.05)。结论自由解剖切面联合容积对比成像(OmniView-VCI)技术是测量盆腔裂孔面积的一种可靠方法。Objective To investigate the application value of OmniView-VCI Technique in 3 Dimensional petvw ultrasound, and study agreement for measurement of pelvic hiatal area and time-consuming between OmniView-VCI Technique and standard 3 Dimensional Rendering Technique. Methods from January to December 2015, in Department of Ultrasound, Dongfeng Affiliated Hospital of Hubei University of Medicine, 231 female subjects underwent examination were selected as the objects, in which, 112 nulliparous and asymptomatic female subjects were selected as control group, 108 female subjects with pelvic floor dysfunction were selected as experimental group. Firstly, the static transperineal 3D sonograi3hic volume of each subject of the two groups was obtained. Each 3D data obtained were analyzed by the OmniView-VCI Technique so as to measure the pelvic hiatal area （twice measurements were conducted by one operator, and one measurement was conducted by the other operator in order to assess intraobserver and intero- bserver repeatability）. The operator who conducted twice measurements later measured the pelvic hiatal area with 3D Rendering Technique in order to assess measurement agreement between OmniView-VCI Technique and 3D Rendering Technique. Repeatab ility of OmniView-VCI Technique and the agreement of measurement results between OmniView- VCI Technique and 3D Rendering Technique were assessed by intra class correlation confficient. Results Through meagreement between the measurement results by OminiView-VCI Technique and 3D Rendering Technique. No systematic differences were discovered through reliability analysis （P 〉 0.05）. As for time consuming of measuring the pelvic hiatal area in two groups, the time-consuming of the OmniView-VCI was obviously less time than the 3D Rendering Technique （P 〈 0.05）. Conclusions OminiView-VCI Technique is a reliable method to measure the pelvic hiatal area.
