高频彩色多普勒超声探讨乳腺癌腋窝淋巴结转移的价值

目的应用高频彩色多普勒超声，探讨乳腺癌腋窝淋巴结转移的超声特征，旨在提高早期检出乳腺癌腋窝淋巴结转移的准确性。方法采用高频二维超声结合彩色多普勒血流显像技术（CDFI），对65例确诊乳腺癌患者进行术前腋窝淋巴结检查，先用二维超声观察腋窝淋巴结的大小、形态、结构、内部回声，再运用CDFI观察其血流情况。结果65例乳腺癌患者均经手术治疗，对切除淋巴结进行病理检查，证实其中39例有同侧腋窝淋巴结转移，26例无淋巴结转移。二维超声显示转移性淋巴结发生形态及内部回声的改变，长短比（US）≤2，皮质增厚，髓质减少甚至消失；非转移性淋巴结皮质呈窄带状，与髓质界限清晰，呈皮质狭窄型。CDFI显示转移性淋巴结血流信号丰富，大多位于周边；非转移性淋巴结仅显示少量血流，且多位于中央。结论转移性淋巴结在二维灰阶超声与CDFI上有特征性表现，高频彩色多普勒超声能较准确地判断乳腺癌腋窝淋巴结的转移情况，具有较高的临床应用价值。

The value of high-frequency color Doppler ultrasonography in the study of axillary lymph node metastasis

Objective Study of the features of axillary lymph node metastasis by high-frequency color Doppler ultrasonography flow imaging(CDFI) in order to make it more accurate to diagnose the initial stage of axillary lymph node metastasis.Methods Sixty-five patients diagnosed with breast cancer were checked to find out the features of the axillary lymph,using the CDFI.Two-dimensional ultrasound was used to observe the size,shape,structure and internal echoes of axillary lymph.CDFI was used to observe the situation ...
