目的: 探讨彩色多普勒超声在乳腺肿块中的诊断价值。材料和方法: 采用超9HDIESP, 探头频率为5~10MHz, 直接接触法, 对115 例乳腺肿块进行分析, 我们应用二维超声和彩色多普勒超声对115 例乳腺肿块进行检测。结果: 良性肿块超声诊断符合率为74-2%(46/62), 误诊率为11-3% (7/62); 恶性肿块超声诊断符合率为89% (47/53), 误诊率为2%(1/53)。超声未定性者占8-7% (10/115), 未发现肿块者占3-5%(4/115), 乳腺恶性肿块诊断敏感性为98% (47/48), 特异性为87%(46/53)。与乳腺良性肿块相比, 恶性肿块无血流(O级) 检出率为7-5% , 显著低于良性肿块(54-4%)(P<0-005), 而中等至多血流(Ⅱ级)检出率显著增高(P<0-005)。但有部分重叠, 即有的良性肿块有多血流, 而恶性肿块反而无血流。动脉的阻力指数在恶性肿块平均为0-74, 而在良性肿块平均为0-63, 两者相比具有显著差异(P< 0-001), 虽然恶性肿块动脉的平均峰值流速34-3cm/s), 比良性肿块(24-1cm/s)增加, 但两者之间不存在显著差异。结论: 彩色多普勒超声对
Objective: To explore the diagnostic value of color Doppler ultrasound in breast masses. Materials and Methods: Ultra-9HDIESP was used. The probe frequency was 5 to 10 MHz. The direct contact method was used to analyze 115 cases of breast mass. We used two-dimensional ultrasound and color Doppler ultrasound to detect 115 cases of breast mass. Results: The diagnostic accuracy of benign masses was 74-2% (46/62). The misdiagnosis rate was 11-3% (7/62). The coincidence rate of ultrasound diagnosis of malignant masses was 89% (47/53). 2% (1/53). Ultrasound indeterminate patients accounted for 8-7% (10/115). No lumps were found in 3-5% (4/115). The diagnosis of malignant breast masses was 98% (47/48). Specificity was 87%. (46/53). Compared with benign breast masses, malignant tumors have no blood flow (Grade O) detection rate of 7-5%, significantly lower than benign masses (54-4%) (P<0-005), and moderate-to-multiple blood flow ( Grade II) detection rate was significantly higher (P <0-005). However, there is a partial overlap, that is, there are multiple blood flow in some benign masses, but there is no blood flow in malignant masses. The arterial resistance index averaged 0-74 in malignant tumors and 0-63 in benign tumors. There was a significant difference between the two (P<0-001), although the average peak flow velocity of the malignant tumor artery was 34-3cm/ s), compared with benign masses (24-1cm/s), but there is no significant difference between the two. Conclusion: Color Doppler Ultrasonography
