MSCTA高级血管分析在椎动脉狭窄诊断中的应用探讨

MSCTA Advanced Vessel Analysis in Disagnosis of Vertebral Artery Stenosis

目的:探讨多层螺旋CT血管造影(Multi-slice Spiral CT Angiography,MSCTA)高级血管分析(AVA)对椎动脉狭窄的诊断意义。方法:对59例经临床考虑为颈椎病患者进行椎动脉CTA,利用高级血管分析AVA技术观察椎动脉形态学变化及与邻近骨结构的关系,准确测量狭窄段长度。结果:59例患者中,37例患者有异常血管,其中双侧血管异常9例,单侧血管异常28例,走行迂曲19支,狭窄26支,4支有管壁钙化性斑块。结论:MSCTA检查可做为椎动脉狭窄筛选的首选检查方法,AVA软件使CTA对椎动脉狭窄程度及原因的分析更准确。

Objective To evaluate the diagnostic value of advanced vessel analysis (AVA) in multi-slice helical CT an-giography (MSCTA)in the evaluation of vertebral artery stenosis.Methods 59 patients with cervical spondylosis were per-formed MSCTA. AVA were used to reconstruct bilateral vertebral arteries.Morphological changes of the vertebral arteries and the influence arising from surrounding bony structure were analyzed by AVA.Results Of 59 arteries,37 vertebral arter-ies were abnormal,including 9 arteries with bi...
