经阴道三维超声检查对子宫腔内病变的诊断价值

The diagnostic value of transvaginal three-dimensional ultrasound for uterine cavity lesions

目的：探讨经阴道三维超声（3D-TVS）诊断子宫腔内病变的价值。方法选择100例疑似子宫腔内病变患者，先行阴道二维超声检查，后行阴道三维超声检查，以宫腔镜检查作为判断阴道二维超声与阴道三维超声检查的标准，将两种诊断方法与宫腔镜检查的结果进行比较分析，并对三维超声影像资料进行分析。结果阴道二维超声检查结果显示，与宫腔镜检查（病变142处）相符的有91处，准确度为64．54％，差异有统计学意义（χ^2＝4．872、4．913、8．198、13．254、10．137，均 P ＜0．05）；阴道三维超声检查结果显示，与宫腔镜检查相符的有132处，准确度为93．62％，差异有统计学意义（χ^2＝2．872、7．387、10．258、18．275、12．259，均P ＜0．05）。阴道三维超声检查下见子宫腔病变声像图较清晰，清楚可见其病灶大小、形态、位置。结论采用阴道三维超声诊断子宫腔内病变，准确性高，影像资料更清晰形象，在宫腔内病变的临床诊断中具有很高的应用价值，值得推广。

Objective To evaluate the value of transvaginal three -dimensional ultrasound（3D -TVS）in the diagnosis of uterine cavity lesions.Methods 100 patients with suspected uterine cavity lesions,firstly underwent transvaginal ultrasound examination,then underwent transvaginal three -dimensional ultrasonography,and the trans-vaginal ultrasound and transvaginal three -dimensional ultrasound examination was judged by hysteroscopy standard. The diagnostic methods and hysteroscopy examination results of the two groups were compared and analyzed,and the three -dimensional ultrasound imaging data were analyzed.Results The ultrasound findings of transvaginal two -dimensional showed that there were 91 cases in line with hysteroscopy（lesion 142）,the accuracy was 64.54%,the differences were statistically significant（χ^2 =4.872,4.913,8.198,13.254,10.137,all P 〈0.05）.At the same time, the three -dimensional ultrasound examination results of vaginal showed consistent with hysteroscopy 132,the accuracy was 93.62%,the differences were statistically significant（χ^2 =2.872,7.387,10.258,18.275,12.259,all P 〈0.05）.Transvaginal three dimensional ultrasound examination of common uterine cavity lesions ultrasound image was clear,and the size,shape and location of the lesion were clearly visible.Conclusion Three dimensional ultra-sound in the diagnosis of uterine cavity lesions has high accuracy,its image data is more clear,and in the clinical diagnosis of uterine cavity lesions has high value of application,and it is worth of promoting.
