摘　　要：目的了解鼻咽癌患者放疗后3 a内颈内动脉变化及螺旋CT应用价值。方法 182例鼻咽癌患者在放疗前及放疗后3 a内行多层螺旋CT增强或CT血管造影检查,分析颈内动脉变化情况。结果 182例(包括放疗前管壁有粥样斑块者13例)患者中,放疗后颈内动脉无明显变化者167例(91.76%),管壁有变化者15例(8.24%)。放疗前管壁有粥样斑块者13例,放疗后出现粥样斑块增多者10例。结论多层螺旋CT可用于观察鼻咽癌患者放疗后3 a内颈内动脉变化情况及原有颈内动脉粥样硬化进程。Objective To investigate the 3-year postradiotherapy changes of internal carotid arteries（ICRs） and the feasibility of spiral CT in patients with nasopharyngeal carcinoma（NPC）. Methods A total of 182 NPC cases underwent enhanced multi-slice spiral CT（MSCT） or CT angiography before and 3 years postradiotherapy. The changes of ICRs were analyzed. Results Of the 182 cases including13 cases of pre-existing atherosclerotic plaques, 167（91.76%） cases presented with no changes of ICRs and 15（8.2%） with obvious changes of ICRs after radiotherapy. The increase of pre-existing atherosclerotic plaques occurred in 10 of 13 cases. Conclusion MSCT is useful for evaluating the changes of ICRs and progression of preexisting atherosclerotic plaques in patients with NPC 3 years postradiotherapy.
