【摘要】 目的探讨经阴道彩色多普勒血流显像技术(TVCDS)对子宫肌瘤和子宫腺肌瘤的诊断和鉴别诊断意义。方法以手术病理结论为标准,回顾性分析子宫肌瘤和子宫腺肌瘤的TVCDS特征,对照比较二者瘤体包膜回声、瘤体内部回声、彩色血流信号和RI值的差异。结果子宫肌瘤与子宫腺肌瘤声像图的鉴别以瘤体周边假包膜特征最为重要;彩色多普勒血流显示瘤体周边出现环状彩色血流,子宫肌瘤组占95.9%,子宫腺肌瘤组占30.8%,组间差异明显;子宫肌瘤和子宫腺肌瘤周边血流阻力指数(RI)分别是(0.53±0.07)和(0.67±0.057),RI≥0.7分别是1.4%和38.5%,组间存在显著性差异(P<0.05)。结论结合瘤体包膜回声、彩色血流信号和RI等超声特征能提高TVCDS对子宫肌瘤和子宫腺肌瘤的诊断和鉴别诊断率。更多还原

【Abstract】 Objective To evaluate Transvaginal color Doppler sonography(TVCDS)for the diagnosis and differetial diagnosis of uterine Adenomyoma(UA)and hysteromyoma(HT).Methods Compared on capsule,echo in interior,color blood signal and RI by postoperative pathological results to study TVCDS characteristics of UA nad TH.Results The ultrasomography feutures of pretendal capsule in peripheral tissue of nodules were highly important for differential diagnosis of hysteromyoma and uterine adenomyoma;The circle of color blood manifestation rates of the color Doppler blood flow ultrasound were 95.9% in HT group and were 30.8% in UA group.There was significant difference between two group;The peripheral tissue resiwstance indeix(RI) of hysteromyoma and uterine adenomyoma was(0.53±0.07) and(0.67±0.053);RI≥0.7 manifestation rates were 1.4% and 38.5% respectively,there also was significant difference betweentwo group(P<0.05).Conclusion Binding capsle,color blood signal and RI can elevate the Diagnosis and differential Diagnosis precision of UA and HT.更多还原
