目的:评价高频彩超对乳腺良、恶性肿块二维声像图和彩色多普勒血流显像的诊断价值。方法:应用高频二维超声对470例乳腺肿块患者进行检查,观察肿块的形态、边界、内部回声、病灶后方回声及有无微小钙化灶。彩色多普勒血流图观察乳腺良、恶性肿块的血流特征。所有病例均经手术治疗,将超声诊断与手术病理诊断结果进行对照。结果:超声诊断乳腺疾病470例,术后病理诊断为恶性者102例,良性368例。超声对恶性肿块的诊断符合率为96.1%,误诊率为3.9%;良性符合率为96.7%,误诊率为3.3%。结论:综合评价乳腺肿块的各种超声征象可提高乳腺疾病诊断的准确性。
Objective: To evaluate the diagnostic value of high frequency color Doppler ultrasound in two-dimensional sonography and color Doppler flow imaging of benign and malignant breast masses. Methods: 470 patients with breast lumps were examined by high-frequency two-dimensional ultrasonography. The morphology, boundary, internal echo, echo behind the lesion and the presence of microcalcifications were observed. Color Doppler flow patterns observed benign and malignant breast blood flow characteristics. All cases were surgically treated, the ultrasound diagnosis and surgical pathological diagnosis were compared. Results: Ultrasound diagnosis of breast disease in 470 cases, pathologically diagnosed as malignant in 102 cases, benign 368 cases. The coincidence rate of ultrasonic diagnosis of malignant tumor was 96.1%, the rate of misdiagnosis was 3.9%, the coincidence rate of benignity was 96.7% and the rate of misdiagnosis was 3.3%. Conclusion: The comprehensive evaluation of various ultrasound signs of breast lumps can improve the diagnostic accuracy of breast disease.
