64层螺旋CT血管造影在头颈部血管病变中的临床应用

64-Slice Spiral CT Angiography in the Head and Neck Vascular Lesions of Clinical Application

    摘要
  • 摘要: 目的:探讨64层CTA在头颈部血管中的诊断价值。方法:收集头颈部血管CTA200例,采用最大密度投影MIP、容积再现VRT、多平面重组MPR及Inspace软件中的减影技术进行三维重建,多角度观察,其中92例有MR、DSA及手术资料,采用双盲法,比较各种影像效果,总结出64层CTA的优缺点。结果:64层CTA用药少、辐射剂量小、扫描及成像速度快,图像清晰、立体感强并可任意方向旋转观察。VRT和MIP是最常用的方法,Inspace软件的减影技术能显示头颈部血管的全貌。结论:64层CTA可作为头颈部血管病变的常规筛选方法,可以普及使用。

     

    Abstract: Objective: To investigate the 64-slice CTA in the head and neck in the diagnosis of blood vessels.Methods: Cases of head and neck vascular CTA200 using maximum intensity projection MIP,volume rendering VRT,MPR and MPR software Inspace subtraction three-dimensional reconstruction techniques,multi-angle observations,of which 92 cases have MR,DSA and surgical information using double-blind comparison of various video effects,summed up the advantages and disadvantages of 64-slice CTA.Results: The 64-slice CTA less medication,small doses of radiation,scanning and imaging speed,image clarity,three-dimensional sense,the direction of rotation can be observed.VRT and MIP is the most commonly used method,Inspace Subtraction software can display the picture of the head and neck blood vessels.Conclusion: The 64-slice CTA can be used as head and neck vascular lesions of conventional screening methods can be widely used.
