摘　　要：目的 评价高频彩色多普勒超声在乳腺癌钼靶X线摄影阴性诊断中的应用价值.方法 将2936例女性乳腺检查中发现病变并经手术或超声引导下穿刺活检病理证实的56例乳腺癌病灶的术前钼靶X线摄影结果 与超声检查结果 进行对比分析,采用双盲法,检查结果 依照BI-RADS标准评判分级,并与病理结果 作对照.结果 56例中,术前超声诊断乳腺癌53例(53/56),超声表现为不规则的低回声肿物图像,部分肿物可见穿入性血流信号及高阻血流频谱;超声呈假阴性3例,超声声像图未见肿物图像,在钼靶X线摄影则表现为恶性钙化,无明确肿块.乳腺钼靶X线摄影诊断乳腺癌47例(47/56),主要影像表现为毛刺样肿块及恶性钙化,呈假阴性9例,肿块最大直径范围约1.5～0.4 cm.结论 超声诊断肿块型乳腺癌有较高的准确性,尤其可检出钼靶X线不能检出的较小的乳腺癌肿块.Objective To Compare high resolution color Doppler sonography and breast digital mammography in evaluation of breast cancer detection. Methods A total of 56 women, aged 33 to 78 years, underwent ultrasound and mammography on the same day. The sonographic and mammographic features of the lesions, as defined by the BI-RADS lexicon, were used to assess the level of suspicion by independent sonographers and radiologists. A biopsy or surgical excision was performed when any of the two investigations was judged to be suspicious for malignancy. Results Three of 56 cases had a diagnosis of false negative in breast carcinoma on ultrasound. These cases showed the calcifications in mammography. Mammography showed nine false negatives in 56 cases. The tumor size was 1.5～0.4 cm in the nine cases. Conclusions Ultrasound may be superior to breast digital mammography for small tumors in breast cancer detection.
