摘　　要：目的探讨超声弹性成像在检测鼻咽癌放疗后颈动脉弹性变化方面的价值。方法选取40例放疗后的鼻咽癌患者作为研究组,同时选取36例未经放疗的鼻咽癌患者作对照组,两组一般资料无统计学差异。分别测量两组患者血液与颈动脉壁的应变率比值,并统计分析。结果研究组应变率比值平均(2.10±0.72),对照组应变率比值平均(1.66±0.63),两者差异有统计学意义(P<0.05)。结论超声弹性成像技术可客观评价放疗后颈动脉壁弹性的变化,为预防颈动脉硬化及其并发症的发生提供依据。[ Objective ] To assess the value of ultrasonic elastography in testing carotid artery elasticity after ra- diotherapy for nasopharyngeal carcinoma. [ Methods ] Forty patients with nasopharyngeal cancer after radiotherapy were selected as study group. In the meantime, thirty-six patients with the nasopharyngeal cancer without radiotherapy were selected as control group. There were no significant differences between the general data of the two groups. The strain ratio of blood and the carotid artery wall of patients was measured and statistically analyzed in both groups. [ Results ] The average strain ratio of the study group was （2.10 ± 0.72）, while that of the control group was （1.66 ± 0.63）. There was a significant difference between them （P 〈 0.05）. [ Conclusions ] Ultrasonic elastography can objec- tively assess carotid artery elasticity after radiotherapy for nasopharyngeal carcinoma, which provides evidence for preventing carotid atherosclerosis and its complications.
