目的探讨彩色多普勒超声血流阻力指数(resistance index,RI)联合血清糖链抗原125(carbohydrate antigen 125,CA125)检测在卵巢良、恶性肿瘤鉴别诊断中的价值。方法检测60例卵巢肿瘤患者血清CA125水平,并行彩色多普勒超声检查记录RI,与手术组织病理结果进行对照,比较RI及RI联合CA125诊断卵巢肿瘤的效能。结果手术组织病理诊断卵巢良性肿瘤45例,恶性肿瘤15例;RI联合CA125诊断良性、恶性卵巢肿瘤的准确率(93.33%、86.67%)高于RI(66.67%、53.33%)(P<0.05)。结论彩色多普勒超声RI联合血清CA125检测鉴别诊断良、恶性卵巢肿瘤优于单独应用彩色多普勒超声RI。
Objective To investigate the diagnostic value of color Doppler ultrasound (RI) combined with carbohydrate antigen 125 (CA125) in the differential diagnosis of benign and malignant ovarian tumors. Methods Serum levels of CA125 were measured in 60 patients with ovarian tumors. RI was recorded with color Doppler ultrasonography. The RI was compared with the histopathological findings. The efficacy of RI and RI combined with CA125 in the diagnosis of ovarian tumors was compared. Results The accuracy of RI and CA125 in diagnosis of benign and malignant ovarian tumors was higher than that of RI (66.67%, 53.33%) (P <0.05) . Conclusion Color Doppler ultrasound combined with serum CA125 RI detection of benign and malignant ovarian tumors is better than the color Doppler ultrasound alone RI.
