摘要
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 Power Doppler Imaging (PDI) in demonstrating blood flow in tumor mass and correlated with the incidence of lymph nodes metastasis in breast cancer, Methods:PDI (Power Doppler Imaging) was used to detect the blood flow within tumor mass of 251 cases of breast cancer, The Doppler spectrum was correlated with the in- cidence of lymph node metastases. Results: Tumor with lymph nodes metastasis were much more hypervascular and higher Pulse Systolic Velocity (PSV) as well as higher resistance index (RI) were shown(P〈0.05). Conclusion: The incidence of lymph node metastasis was closely correlated with the blood flow within the tumor mass in breast cancer,
