摘　　要：目的:评价64层螺旋CT血管分析(vessel analysis,VA)软件对颅内动脉瘤的诊断价值。方法:对40例蛛网膜下腔出血患者完成64层螺旋CT减影CTA增强扫描后,选取50段病变或可疑病变脑动脉分为两组:分别采用减影CTA图像和减影CTA图像+VA图像作诊断,诊断结果以DSA为准,比较2组诊断的特异性和敏感性。结果:减影CTA结合VA对颅脑动脉瘤诊断的特异性和敏感性均高于单独的减影CTA。VA对脑动脉瘤瘤颈显示效果优于减影CTA。结论:VA软件对颅内动脉瘤的诊断具有很大的临床价值。减影CTA结合VA的合理应用能更好的显示动脉瘤,提高动脉瘤的检查率,可作为筛查动脉瘤的首选方法。Objective：To study the value of 64-row multislice spiral CT vessel analysis software in the diagnosis of intracranial aneurysms.Methods：Patients（n=32） with subarachnoid hemorrhage were underwent 64-row multislice spiral CT,all of the data were used to reconstruct the digital subtraction CTA（DSCTA） and 48 segments of abnormal vessel were analysised by vessel analysis software.Diagnosis was done by two groups： DSCTA and DSCTA＋VA,the diagnostic specificity and sensitivity of two groups were compared according to the results of DSA.Results：The diagnostic specificity and sensitivity of group DSCTA＋VA were higher than group DSCTA.Intracranial aneurysms necks measured were better done by VA than DSCTA.Conclusion：The vessel analysis software has marked clinical value in detecting intracranial aneurysms.Combine DSCTA and VA could made the diagnosis of intracranial aneurysms more accurately,as the first diagnostic tool for the intracranial aneurysms.
