目的通过彩色多普勒超声检查监测鼻咽癌患者颈部淋巴结转移灶放疗前、后超声影像学特征的变化情况，从而判定放疗疗效的价值和制定相应的治疗计划。方法应用彩色多普勒超声检查在放疗前后对168例鼻咽癌患者经临床及病理学检查确诊的225个颈部淋巴结转移灶的长径（L ）、短径（S ）、长径/短径（L/S ）、收缩期峰值流速（PSV）、阻力指数（RI）、血流强度进行对比观察。结果225个颈部淋巴结转移灶放疗前与放疗4 w 后的L、S、L/S、PSV、RI、血流强度的比较差异有统计学意义（P均＜0．001）。结论彩色多普勒超声影像学检查在评价鼻咽癌颈部淋巴结转移灶放疗的近期疗效以及预后的判定具有重要的临床价值。

Objective To determine the changes of nasopharyngeal carcinoma neck metastatic lymph node before and after radiotherapy by ultrasound monitoring ,and the value of radiotherapy and then make ap-propriate treatment plans .Methods Monitored by color Doppler ultrasound ,168 nasopharyngeal carcino-ma patients treated with radiation therapy are well-established by clinical and pathological .Then a compar-ative observation are carried on to examine 225 neck metastatic lymph nodes in long diameter (L ) ,short diameter (S) ,long diameter and short diameter (L/S) ,peak systolic velocity (PSV) ,resistance index (RI) ,blood flow intensity .Results The comparison of before radiotherapy and radiotherapy for 4 weeks after the 225 neck metastatic lymph nodes L ,S ,L/S ,PSV ,RI ,flow intensity had significant difference . Conclusion Ultrasound imaging tests evaluate neck metastatic lymph nodes radiotherapy treatment effica-cy and prognosis judgment has important clinical value .
