三维超声造影在附件区包块中应用的可行性

目的 探讨经阴道三维超声造影（transvaginal three-dimensional ultrasonography，3D-CEUS） 在附件区包块检查中应用的可行性。方法 对38 例附件区肿块先后进行经阴道二维超声造影（transvaginal two-dimensional ultrasonography，2D-CEUS）和3D-CEUS 检查。重建3D-CEUS 图像后，根据清晰度将图像质量评为高质量、一般、低质量，分析其对临床诊断的影响。结果 38 例附件区包块的3D-CEUS 图像中高质量者30 例（78.9%），质量一般者6 例（15.8%），低质量者2 例（5.3%） ；与2D-CEUS 相比，36 例（94.7%） 能增加诊断信息。结论 3D-CEUS 图像能清晰显示多数附件区包块的血管特征，可作为2DCEUS的有益补充，用于附件区包块的鉴别诊断。

Application of 3-dimensional contrast-enhanced ultrasonography in adnexal masses

Objective To study the application of transvaginal 3-dimensional contrast-enhanced ultrasonography （3D-CEUS）in adnexal masses. Methods Adnexal masses in 38 women were detected by 2D-CEUS and 3D-CEUS, respectively. Effect of 2DCEUS and 3D-CEUS images on diagnosis and clinical outcome of adnexal masses was assessed according to their clarity. Results The 3D-CEUS images were excellent on 30（78.9%） adnexal masses, good on 6（15.8%） adnexal masses, and poor on 2（5.3%） adnexal masses. The 3D-CEUS images could increase more information for the diagnosis of 36（94.7%） adnexal masses than the 2D-CEUS images. Conclusion The 3D-CEUS images show more vascular features of adnexal masses than the 2D-CEUS images, and can thus be used for the differential diagnosis of adnexal masses as a supplementary tool of 2D-CEUS.
