| 目的 观察三维超声自由解剖切面（Omniview）联合容积对比成像（VCI）技术（O+V技术）测量肛提肌裂孔面积的价值。方法 回顾性分析283名接受经会阴实时三维盆底超声检查女性，对比观察不同医师（医师1、医师2）采用O+V技术及立体渲染模式（R模式）测量最大瓦尔萨尔瓦状态下最小肛提肌裂孔面积所用时长，并采用组内相关系数（ICC）评估观察者内、观察者间及不同方法间测量结果的一致性，评价O+V技术用于测量肛提肌裂孔面积的价值。结果 医师1及2采用O+V技术测量肛提肌裂孔面积所用时长均明显低于R模式（P均<0.01）。医师2采用O+V技术与R模式测量肛提肌裂孔面积的一致性均好（ICC均>0.75），2次O+V技术测量结果的一致性好（ICC>0.75）；医师1、2采用O+V技术测量结果的一致性均好（ICC均>0.75），医师1采用O+V技术与医师2采用R模式测量结果的一致性亦好（ICC>0.75）。结论 三维超声O+V技术用于测量肛提肌裂孔面积耗时短、准确度佳，值得临床推广及应用。 |

| Objective To observe the value of three-dimensional ultrasound Omniview combined with volume contrast imaging (VCI) technique (O+V technique) for measuring the area of levator ani hiatus. Methods Data of 283 women who underwent transperineal real-time three-dimensional pelvic floor ultrasound were retrospectively analyzed. The time consuming of measuring the minimum area of levator ani hiatus under the maximum Valsalva maneuver with O+V technique and multi-volume rendering mode (R mode) by different doctors (doctor 1 and doctor 2) were observed and compared, and the intra-class correlation coefficient (ICC) was used to evaluate both inter- and intra-observer and intra-method variabilities, and the value of O+V technique was analyzed. Results The time consuming for measuring the area of levator ani hiatus with O+V technique by doctor 1 and 2 were both less than those with R mode (both P<0.01). The consistencies of the area of levator ani hiatus measured with O+V technique and R mode by doctor 2 were good (both ICC>0.75), as well as measured twice with O+V technique by doctor 2 (ICC>0.75), measured with O+V technique by doctor 1 and 2 (both ICC>0.75) and measured with O+V technique by doctor 1 and with R mode by doctor 2 (ICC>0.75). Conclusion Three-dimensional ultrasound O+V technique was less time consuming with good accuracy for measuring the area of levator ani hiatus, hence being worthy of clinical promotion and application. |
