摘　　要：目的:探讨64排螺旋CT高级血管分析技术在椎动脉型颈椎病(CSA)诊断和病因分析方面的临床价值。方法:对73例临床拟诊为CSA的患者进行64排螺旋CT检查,所得数据采用容积再现(VR)、最大密度投影(MIP)和血管分析(AVA)等重建技术进行后重建处理,并与结合原始图像进行对比分析,评价几种后重建方法诊断CSA的差异。结果:AVA重建的图像质量最佳,其中Ⅰ级图像为55例(75.34%),而MIP和VR则分别为65.75%和64.38%。AVA对椎动脉钙化、椎动脉变异、椎动脉狭窄、椎动脉发育不良显示与MIP相比,均显著增加(P<0.05);AVA对钩椎关节增生、椎动脉钙化、椎动脉狭窄、椎动脉发育不良显示与VR相比,均明显增加(P<0.05)。结论:AVA在无创诊断和随访CSA方面有着重要的临床价值,为CSA临床应用开辟了一条安全、可靠、无创、便捷的新方法。Objective： To study clinical value of 64 row spiral CT advanced vessel analysis in CSA diagnosis and etiological analysis. Methods： A total of 73 cases who were clinically suspected as cervical spondylosis of vertebral arterytype received MSCTA. Images were postprocessed by using AVA, MIP and VR. AVA was compared with VR, MIP in detecting cervical spondylosis of vertebral artery type. Results： Image reconstruction was the best treatment of AVA, including grade I image in 55 cases （75. 34%）, while MIP and VR were 65.75% and 64.38%. Compared with MIP, maldevelopment rate of vertebral ar- tery calcification, anomalous vertebral artery, vertebral artery stenosis, vertebral artery hypoplasia by AVA was increased signifi bral joint hyperplasia, ver by AVA was also increase ca te d noninvasive diagnosis and fo ntly （P〈0.05） while compared with VR, maldevelopment rate of uncoverte- bral artery calcification, vertebral artery stenosis, vertebral artery hypoplasia significantly （P〈0.05）. Oonclusion： AVA has important clinical value in llow-up of CSA. It provides a safe, reliable, noninvasive, convenient met for the clinical application of CSA. the
