目的探讨经阴道超声二维及彩色多普勒诊断子宫肌瘤及子宫腺肌瘤的临床应用价值。方法对35例子宫腺肌瘤、42例子宫肌瘤患者行经阴道彩色多普勒超声,分析其二维及彩色多普勒血流特征,并测定各组子宫动脉、病灶周边及内部RI。选取50名健康妇女为正常对照组。结果二维图像上子宫肌瘤及子宫腺肌瘤均呈特征性改变。CDFI示子宫肌瘤及子宫腺肌瘤患者子宫动脉平均RI低于正常对照组(P<0.05)。子宫肌瘤周边血流丰富,内部血流信号稀少或无;子宫腺肌瘤周边血流信号稀少,内部见丰富或星点状血流信号,子宫肌瘤周边及内部动脉RI均低于子宫腺肌瘤内部动脉RI(P<0.05)。结论经阴道彩色多普勒为子宫肌瘤及子宫腺肌瘤的鉴别诊断提供有价值的信息。
Objective To investigate the clinical value of transvaginal sonography in the diagnosis of uterine fibroids and adenomyoma by two-dimensional and color Doppler ultrasound. Methods Transvaginal color Doppler ultrasonography was performed on 35 cases of adenomyosis of the uterus and 42 cases of uterine fibroids. The two dimensional and color Doppler flow characteristics were analyzed. The uterine artery, peripheral and internal RI of each group were measured. Fifty healthy women were selected as normal control group. Results Two-dimensional images of uterine fibroids and adenomyoma showed a characteristic change. CDFI showed uterine fibroids and uterine adenomyoma uterine artery RI was lower than the normal control group (P <0.05). Uterine fibroids around the rich blood flow, the internal blood flow signal is sparse or absent; peripheral adenomyosis sparse peripheral blood signal, the internal see rich or astrocytic blood flow signal, uterine fibroids peripheral and internal artery RI were lower than the uterine gland Internal fibroids RI (P <0.05). Conclusion Transvaginal color Doppler provides valuable information for the differential diagnosis of uterine fibroids and adenomyomas.
