摘　　要：目的:探讨64层螺旋CT颈部动脉成像技术的临床应用。方法:回顾性分析65例经64层螺旋CT颈部动脉造影检查病例,使用对比剂跟踪技术,后处理使用容积再现技术(VRT)、最大密度投影(MIP)、多平面重建(MPR)、曲面重建(CPR)、仿真内窥镜(CTVE)等技术重建,分析其发育变异、斑块性质、狭窄程度等情况,并结合临床进行分析。结果:65例130条颈动脉中,34条无异常,颈内动脉瘤8条,粥样斑块并狭窄88条。88条狭窄的颈动脉中,轻度狭窄59条(67.0%),中度狭窄22条(25.0%),重度狭窄5条(5.7%),闭塞2(2.3%)条;130条椎动脉中,正常52条,先天性变异27条,粥样斑块并狭窄46条,椎动脉受增生骨质压迫5条。51条狭窄的椎动脉中,轻度狭窄40条(78.4%),中度狭窄8条(15.7%),重度狭窄3条(5.9%)。结论:应用64层螺旋CT颈部CTA检查,可同时完成颈动脉与椎动脉血管成像,准确显示血管病变的类型、程度,为临床治疗提供科学的依据。Objective：To investigate the clinical application of 64 row helical computed tomography in cervical arteries. Methods： 65 patients underwent angiography of cervical arteries by 64 row helical CT were analyzed retrospectively. All patients were examined with Smartprep. Image postprocessing was taken with volume rendering（VR）, maximum intensity projection （MIP）, muhiplanar reconstruction （MPR）, curved planar reformation （CPR） and CT virtual endoscopy （CTVE）. The developmental variation, plaque features and stenesis degree were analyzed. Results：Among 130 internal carotid arterys, 34 cases had no abnormal, 8 cases with internal carotid aneurysms, 88 cases plaque formation of carotid arteries were found with stenosis, the mild stenesis 59 cases （67.0%）, the moderate stenosis 22 cases （25.0 % ）, the severe stenosis 5 cases （ 5.7 % ）, artery occlusion 2 cases （2.3 % ） ; Among 130 vertebral arterys, 52 cases were normal, 27 cases were congenital variations, 46 cases were found with plaque formation, 5 cases with compression of vertebral artery by hyperes- tcogeny. 51 cases of vertebral artery stenosis, the mild stenosis 40 cases （78.4%）, the moderate stenosis 8 cases （15.7%）, the severe stenosis 3 casesa （5.9%）. Conclusion：64 row helical CT angiography is safe and feasible to display carotid atrtery and vertebral artery clearly in one examination, and the typing diagnosis is helpful to guide therapy.
