摘要
目的 探讨二维及彩超对乳腺癌及腋窝转移性淋巴结的诊断价值。方法 回顾性分析53例乳腺癌和27例腋窝癌性转移性淋巴结的二维声像图及CDFI特征,所有病例均经手术病理证实。结果 本组乳腺癌二维超声声像图极大部分肿块形态不规则,边界不清,内部回声低或不均匀,纵横比>1占32.08％,CDFI血流显示率86.79％,RI平均为0.54。腋窝癌转移性淋巴结二维声像特征:淋巴结肿大,呈圆形或卵圆形低回声结节,多发式融合在一起,周边及内部见血流信号。结论 二维结合CDFI提高了乳腺癌及腋窝转移性淋巴结的诊断准确性,为临床采用不同的治疗手段提供无创性综合检测分析方法。
Purpose To evaluate the value of B - mode and color Doppler ultrasoriography for diagnosing breast carcinoma and axillary metastatic lymph node. Methods Fifty - three cases of breast carcinoma and 27 cases axillary metastatic lymph node had been analyzed restrospec-tively , and all cases were confirmed by pathology . Results US features of breast carcinoma were irregular, ill defined border, low or inhomogeneous echogenecity, RI 0.54, L/T > 1 占 23.08 %. The detection rate of flow singals by CDFI was 86.79 % (46/53 ) . The B - mode ultrasound sonographic morphlolgic characteristics of axillary metastatic lymph node was enlarged lymph node, orbicula or oval hypoechogenicity nodule, multiple or mixed, blood folw were seen in out arounding and inside of it. Conclusions B - mode ultrasound and CDFI can improve the diagnostic accuracy of breast carcinoma and axillary metastatic lymph node.
