    摘要:

    目的:探讨双源CT双能量成像在头颈部血管成像中的应用价值-方法:回顾性分析141例行颈部双能量血管成像病例资料,评价颈部血管双能量成像的图像质量,并用多种后处理方法对血管病变进行综合分析-结果:141例患者均清晰显示颈部动脉全貌,28例颈部血管未见异常,9例血管有发育变异,104例发现异常血管病变-99例有粥样硬化斑块的患者中,发现140段血管不同程度的狭窄,6例合并颅内动脉瘤-5例无粥样硬化斑块的患者中发现3例颅内动脉瘤,2例颅内动静脉畸形-结论:作为一种无创-经济-简便的检查方法,双源CT双能量成像能快速有效去除颈部及颅底骨骼,多方位显示颈部动脉狭窄程度-管壁粥样硬化斑块的特点以及动脉瘤的大小-形态,在颈部血管病变的筛查-诊断及治疗后随访中有重要的作用-

    Abstract:

    Objective: To investigate the application value of dual-source computed tomography dual-energy angiography in carotid arterial. Methods: We retrospectively analyzed the images of 141 patients detected by dual- energy angiography,evaluated the quality of the images and used various reconstruction methods to analyze the pathological changes in carotid arterial. Results:High quality images were acquired in all of the 141 cases apart from 28 cases with no abnormalities and 9 cases showed normal variants of blood vessels,abnormalities of blood vessels were detected in 104 patients. 140 vessels with stenosis were detected in 99 patients with atherosclerotic plaque,including 6 patients with aneurysms,3 aneurysms and 2 arteriovenous malformation were detected in 5 patients without atherosclerotic plaque. Conclusion: As a non-invasive,cheap and convenient method,DE-CTA can remove bone in the neck and skull base,visualize stenosis,atherosclerotic plaque and aneurysms of carotidartery. DE-CTA possesses important effect to screen,diagnose,and track neck vascular diseases.
