目的探讨彩超在诊断宫外孕中的价值,进一步提高宫外孕超声诊断的准确性,减少误诊和漏诊。方法收集本院自2002年11月至2005年6月宫外孕超声病例,分析和总结黑白超声及彩超的图像特点。结果宫外孕肿块外周组织和肿块内组织的彩色血流信号明显增多,外周组织血流信号多呈环形围绕肿块,肿块内、外血流RI值明显下降,RI值常小于0·45。结论彩超在诊断宫外孕时有特殊的敏感性和血流参数指标,大大提高了单纯依靠黑白B超诊断宫外孕的准确率,在诊断宫外孕中有重要的临床价值。
Objective To explore the value of color Doppler ultrasound in the diagnosis of ectopic pregnancy, to further improve the accuracy of ultrasonic diagnosis of ectopic pregnancy, reduce misdiagnosis and missed diagnosis. Methods The echocardiographic cases of ectopic pregnancy in our hospital from November 2002 to June 2005 were collected and analyzed. The features of the images were analyzed and summarized. Results The echocardiographic signals of peripheral blood vessels and intraepithelial masses in ectopic pregnancy were significantly increased. The peripheral blood flow signals were mostly in the shape of a ring around the tumor. The RI values of blood flow inside and outside the tumor were significantly decreased, and the RI value was often less than 0. 45. Conclusion Color Doppler ultrasound in the diagnosis of ectopic pregnancy with special sensitivity and blood flow parameters, which greatly improves the accuracy of the diagnosis of ectopic pregnancy by purely B-ultrasound, in the diagnosis of ectopic pregnancy have important clinical value.
