目的:研究乳腺癌的血流分布特点及其与腋窝淋巴结转移的关系。方法:通过能量多普勒(PDI)检测251例乳腺癌肿块内血流信号,结合波谱分析其与腋窝淋巴结转移的关系。结果:有淋巴结转移组乳腺癌肿瘤血供明显丰富,且最大血流峰值(PSV)和阻力指数(RI)较高(P<0.05)。结论:乳腺癌肿瘤血流分布情况与腋窝淋巴结的转移有很大的相关性。
Objective: To study the distribution of blood flow in breast cancer and its relationship with axillary lymph node metastasis. Methods: The blood flow signals in 251 cases of breast cancer were detected by energy Doppler (PDI), and their relationship with axillary lymph node metastasis was analyzed by spectroscopy. Results: The blood supply of breast cancer with lymph node metastasis was significantly enriched, and the maximum peak blood flow (PSV) and resistance index (RI) were higher (P <0.05). Conclusion: The distribution of blood flow in breast cancer is closely related to the metastasis of axillary lymph nodes.
