经阴道彩色多普勒超声鉴别诊断卵巢良恶性肿瘤的研究

目的 探讨经阴道彩色多普勒超声鉴别诊断卵巢良、恶性肿瘤的价值。方法对81例卵巢肿瘤患者术前行经阴道彩色多普勒超声检查。分析瘤内血流分级、瘤内动脉血流参数。结果 良性组血流以0级、I 级为主，占88％，恶性组以Ⅲ级为主，占70％，两组比较有显著差异（P＜0.05），卵巢恶性肿瘤动脉血流RI值、PI值明显低于良性组（P＜0.05）。结论 RI、PI、血管分级是鉴别卵巢良、恶性肿瘤的重要指标，对评价预后有一定的参考价值。

Study on Transvaginal Color Doppler UltrasOnOgraphy in Ovarian Tumors

【Abstract】 Objective The purposes of this study were to explore the value of transvaginal color Doppler uhrasonography(TVCDU)in diagnosing ovarian tumors．Methods 81 ovarian tumors were examined preoperatively with TVCDU．The vascular indices(PSV、EDV、RI、PI)，blood flow grading were recorded and analyzed in order to diferentiate benign and malignant ovarian tumors. Results In the malignant group， grade 0～ I accounted for 88％；in benign group，grade Ⅲ accounted for 70％，the discrepancy of blood flow grading between the malignant group and benign group had statistical significance (P <0．05).RI and PI in malignant group were lower than that in benign group(P <0．05)．Condusion TVCDU was an effective method for diferentiation of malignant from benign ovarian tumors.
