目的评价二维及彩色多普勒超声在卵巢肿物鉴别诊断中的价值。方法分析经二维超声、多普勒超声检查并经手术病理证实的卵巢肿物患者117例。结果62例卵巢恶性肿瘤中,表现囊实混合性及实性者占90.5%。卵巢恶性肿瘤峰值流速19.84±6.78cm/s,平均流速11.73±4.76cm/s,PI值0.71±0.22,RI值0.46±0.10,呈现出高速低阻的血流特点。结论经阴道二维及彩色多普勒超声诊断卵巢恶性肿瘤具有较高诊断价值;卵巢恶性肿瘤血流多普勒成像为高速低阻血流特点。
Objective To evaluate the value of two-dimensional and color Doppler ultrasound in the differential diagnosis of ovarian tumors. Methods 117 cases of ovarian masses confirmed by two-dimensional ultrasonography, Doppler sonography and pathological examination were analyzed. Results In 62 cases of ovarian malignant tumors, 90.5% showed mixed and solid cystic and solid. The peak flow rate of ovarian cancer was 19.84 ± 6.78cm / s, the average flow rate was 11.73 ± 4.76cm / s, the PI value was 0.71 ± 0.22, the RI value was 0.46 ± 0.10, showing the characteristics of high-speed and low-resistance blood flow. Conclusion Transvaginal two-dimensional and color Doppler ultrasound diagnosis of ovarian cancer has high diagnostic value; Doppler flow imaging of ovarian malignant tumor is characterized by high-speed low resistance blood flow.
