目的:比较彩色多普勒超声(CDFI)与超声弹性成像(UE)鉴别乳腺良恶性肿块的价值。方法:选取40例乳腺病患者,共81个结节,分别行超声弹性成像及多普勒超声检查,比较分析这两种方法诊断乳腺肿块良恶性的敏感性、特异性、准确性,以术后病理结果为金标准。结果:病理检查显示,良性62例,恶性19例。CDFI与UE的敏感性、特异性、准确性分别为73.7%、72.6%、72.8%和84.2%、91.9%、90.1%。UE特异性、准确性与CDFI差异有统计学意义(P<0.05)。结论:UE诊断乳腺良恶性病变优于CDFI。 Objective: To compare the value of color Doppler ultrasound (CDFI) and ultrasound elastography (UE) in differentiating benign and malignant breast masses. Methods: Totally 81 nodules were selected from 40 patients with breast diseases. Ultrasound elastography and Doppler echocardiography were performed respectively. The sensitivity, specificity and accuracy of the two methods in diagnosing benign and malignant breast lesions were analyzed comparatively Post-pathological results for the gold standard. Results: Pathological examination showed 62 cases of benign and 19 cases of malignant. The sensitivity, specificity and accuracy of CDFI and UE were 73.7%, 72.6%, 72.8% and 84.2%, 91.9% and 90.1% respectively. The differences of UE specificity, accuracy and CDFI were statistically significant (P <0.05). Conclusion: UE diagnosis of benign and malignant breast lesions than CDFI.
