摘　　要：目的与超声(DUS)、数字血管造影(DSA)诊断结果对比分析,评价CT头颈部动脉血管造影(CTA)对颈部动脉血管狭窄性病变诊断准确性、敏感性及价值。方法对50例有临床症状患者行颈部动脉血管MSC-TA检查,应用最大密度投影M IP,多平面重建MPR,容积重建VR,高级血管分析软件AVA,进行重建,采用NASCET标准测量血管狭窄程度,对比超声及DSA一周内诊断结果,分析头颈部CTA对动脉血管狭窄性病变诊断价值。结果 CTA对轻度血管狭窄性病变、中重度血管狭窄性病变(尤其是椎动脉狭窄性病变)敏感度较高,准确度较DUS更高,血管中重度狭窄与DSA结果基本相同,并且能跟检出DSA漏诊轻度血管狭窄;对血管壁斑块(尤其是钙化斑块)敏感度及准确度较DSA高,对较小斑块及血管内膜增厚性病变超声敏感度更高。结论颈动脉CTA作为一种无创性检查方法对颈动脉血管斑块及血管狭窄性病变诊断有重要价值和帮助,可以颈部动脉血管检查的首选和重要方法,超声和DSA检查可以有效互补。Objective To evaluate the acuuracy,susceptiveness of CTA in diagnosis of Carotid stenosis by comparing the Results of DSA and DUS.Methods 50 cases were checked by carotid artery MSCTA and reconstructed by MIP,MPR,VR and AVA.The degree of arteriarctia were measured by NASCET criterion and compared with the results of DSA and DUS within a week.Results CTA is more susceptive and more accurate than DUS in diagnosis of arteriarctia and more effective in diagnosis of atheromatous plaque than DSA.Conclusion As a effective non-invasive method in diagnosis of Carotid stenosis and atheromatous plaque,CTA could be used as a preferred method in cervical artery check,accompanied by DUS and DSA.
