摘  要: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:Objective:To study diagnostic value of color doppler sonography for human mammary mass.Materials and Methods:Direct touch method was carried out with super 9HDI ESP type ultrasound instrument and 5~10 MHz probe for 115 cases of mammary masses.Results:Diagnosis-coincidence rate and misdiagnosis rate for benign mass was 74 2%(46/62),and 11 3%(7/62)respectively,and for malignant mass,was 89%(47/53)and 2% (1/53).8 7% cases of masses were indistinguishable between benign and malignance Mass was undetectable in 3 5% cases(4/115).Sensitivity and specificity of color doppler ultrasound diagnosis was 98%(47/48) and 87%(46/53) for mammary masses.Flow-undetected rate decreased significantly in malignant masses,and increased in middle and high flow,compared with benign ones.Significant difference was observed for resistance index between malignancies and benign ones(0 63 vs 0 74),but not for average peak flow velocities.Conclusion:Color doppler sonography is proved to have clinical value for differentiatial diagnosis of mammary malignant and benign masses.
