摘　　要：目的 研究鼻咽癌颈转移淋巴结放疗前后多普勒血流信号特征。方法 首程放疗的５２例鼻咽癌患者的１３４枚颈转移淋巴结，分别于放疗前，放疗２周、４周、６周和放疗后１月行彩色多普勒能量图检查，分析其血流信号特征。结果 放疗前颈转移淋巴结以周边型（７６．９２％）血流，Ⅰ、Ⅱ级（４２．３１％、３６．５４％）血流强度为主；放疗后阻力指数（Ｒ）、收缩期峰值流速（Ｖｍａｘ）值较放疗前显著下降（Ｐ＜０．０５）。结论 鼻咽癌颈转移淋巴结放疗前以周边型血流、Ⅰ～Ⅱ级血流强度为主，放疗后淋巴结血供明显降低甚至消失，这对放疗后随访、判断颈淋巴结复发有意义。Objective:To research the charcteristics of Deppler flew sigul of cervical lymph nodes with metastasis from nasopharyngeal carci- noma before and after radiotherapy. Metbods: 134 metastatic cervical lymph nodes from 52 nasopharyngeal carcinoma patients who were first to re- ceive radiotherapy were studied with Color Doppler Energy(CDE) in preradiotherapy and after 2 weeks, 4 weeks and 6 weeks radiotherapy as well as 1 month after radiotherapy. The chaiacteristics of flew signal were analysed. Results: Before radiotherapy, as for the blood flew signal, peripheral pat- tem accounted for 76. 92 % of the cervical lymph nodes with metastasis from nasopharyngeal carcinoma, as for the intensity of blood flow, Ⅰ and Ⅱ grade accouned for 42. 31 % and 36. 54% respectively, After radiotherapy, the value of RI and Vmax decreased significantly compared with that in pre - radiotherapy (P < 0.05). Conclusion:The peripheral pattems and Ⅰ - Ⅱ grade intensity of blood new dominated in the blood supply prop- erty of metastatic cervical lymph nodes for nasopharyngeal carcinoma.The blood supply of cevvical metastatic lymph nodes decreased even disap- peared after radiothrapy. All of those are significant for following up and judging the lymph nodal recurrence.
