经阴道三维超声结合透明成像诊断宫腔内疾患

The value of transvaginal color Doppler flow imaging in diagnosis of intrauterine disease

目的:探讨经阴道三维超声与透明成像在诊断宫腔内疾患的临床价值。方法:对我院疑有宫腔内赘生物67例住院患者行经阴道超声检查,并取其三维及透明成像(三维血流成像),并与病理诊断结果进行对照分析。结果:三维超声可更清晰显示黏膜下肌瘤周边的子宫内膜中断,透明成像对子宫黏膜下肌瘤周边环形血流比彩色多普勒血流显示更敏感,呈现一种特征性的"火球"样图像,与二维超声相比有极显著优势(P<0.01)。三维超声可更清晰显示息肉的内部结构及内膜周边的完好连续性,透明成像显示其内血流信号不甚丰富。三维超声可更清晰显示早期内膜癌患者内膜边缘的状态及内部回声的变化,易于观察肌层侵润的深度,病变区丰富及走形紊乱的血流信号,较二维超声有显著优势(P<0.05)。结论:经阴道彩色多普勒三维超声结合透明成像能更精确显示宫腔内疾患形态特征、团块与宫腔关系及其内部血流情况,较普通经阴道超声有明显优势,更利于早期诊断宫腔内疾患。

Objective：To assess the value of transvaginal 3D sonogrphy and glass body image in the diagnosis of intrauterine disease.Methods：Transvaginal 3D sonography and glass body image were performed in 67 patients with suspected intrauterine disease.The ultrasonic findings were correlated with pathological findings.Results：The endometrium interruption surrounding submucosal myoma could be showed more accurately by 3D sonography.The glass body image could be more sensitive in the detecton of peripheral color ring,which was demonstrated as a characteristic ＂fire ball＂ image,than 2D sonography.Furthermore,the internal structure of endometrial polyps and the endometrial continuity surrounding the polyps could be showed up in 3D ultrasound.The glass body image demonstrated that color flow in endometrial polyp was not rich.The rim of the endomitrum,internal echo change,the depth of myometrial invasion and the abundant internal vascularity could be more clearly showed in the 3D sonography.Conclusion：3D sonography has important value in the early detection of intrauterine disease.
