16层螺旋CT血管造影在颅外段颈内动脉狭窄病变诊断中的应用研究 【摘要】目的：探讨16层螺旋CT血管造影（16-MSCTA）在颅外段颈内动脉狭窄病变诊断中的应用价值。方法：回顾性分析了行颅颈部16-MSCTA检查的拟诊为前循环缺血卒中的23例患者的临床资料，23例患者一周内先后行16-MSCTA与DSA检查，评价16-MSCTA对颅外段颈内动脉狭窄诊断的敏感性、特异性、准确性。结果：23例患者行16-MSCTA和DSA检查共得到46支颅外段颈内动脉图像。16-MSCTA共诊断正常18支，狭窄28支，中度及以上狭窄共20支，占43.48%。DSA共诊断正常19支，狭窄27支，中度及以上狭窄共18支，占39.13%。16-MSCTA对中度及以上狭窄程度诊断评价的敏感性、特异性、准确性分别为90.0%、100.0%、94.7%。结论：16-MSCTA在颅外段颈内动脉狭窄程度分级的判定中与DSA较高的一致性，16-MSCTA可以作为颅外段颈内动脉狭窄的筛查手段之一。 【关键词】颈动脉狭窄；颅外段；16排螺旋CT；血管造影术 Applied Research of 16 segments of multislice computed tomography angiography in the diagnosis of carotid artery atherosclerotic plaque Du Ming, CT Room of Tong Chuan District Red Cross Hospital, Da Zhou City, Si Chuan Province 635000 Zhang Lian-shan, CT Room of Peoples Hospital of Da Xian, Si Chuan Province 635000 [Abstract] Objective: To explore the applied value of 16-MSCTA in herosclerotic sclerosis lesion of internal carotid artery. Methods: The clinical data of 23 cases of patients with ischemic cerebrovascular disease were retrospectively studied. All the 23 cases of patients were checked by 16-MSCTA and DSA in a week and 16-MSCTA diagnostic accuracy, sensitivity and specificity of extra-cranial internal carotid artery stenosis were assessed. Results: After being checked by 16-MSCTA and DSA, 46 branches of carotid artery images were formed. Of all the images checked by 16-MSCTA, normal ones account for 18, stenosis 28, with moderate and severe stenosis 20 (43.48%). Of all the images checked by DSA, normal ones account for 19, stenosis 27, with moderate and severe stenosis 18 (39.13%). The findings showed that 16-MSCTA diagnostic accuracy was 94.7%, sensitivity 90.0% and specificity 100.0%. Conclusion: Assessment of different levels of herosclerotic sclerosis lesion of internal carotid artery by 16-MSCTA was consistent with that by DSA. 16-MSCTA can be used as one of the methods to diagnose the atherosclerotic sclerosis lesion of internal carotid artery [Key words] carotid artery stenosis; extracranial c
