摘　　要：目的探讨多排螺旋CT（MSCT）数字减影血管造影术在颅内微小动脉瘤诊断中的临床应用价值。方法回顾分析本院31例可疑颅内微小动脉瘤患者，应用MSCT数字血管造影术（简称减影CTA）进行颅内动脉成像检查，全部患者均进行了手术确诊或DSA检查，并将两种检查结果进行比较。结果全部患者中手术及DSA造影共检出微小动脉瘤35个，采用数字减影CTA共检出32个，敏感性为91．4％。结论MSCT数字减影血管造影术是一种安全、无创的新型检查方法，具有较高的特异性及敏感性，在颅内微小动脉瘤的初步筛选及评价方面具有较高的临床应用价值。Objective ：To study the value of the application of MSCT digital subtraction CT angiography （DSCTA）in the diagnosis of intracranial micro-small aneurysm. Method MSCT digital subtract angiography were undertaken in 31 patients who were suspected to have intracranial micro-small aneurym. Digital subtract angiography was also undertaken in all the patients. All the patients were treated by surgical operation. Results： By operation and DSA 35 cases of micro-small aneurysms were founded, By DSCTA,32cases of aneurysms were found, The sensitivity and specificity of subtract CTA was 91.4%. Conclusion MSCT subtract CTA is a new techuich, which is safe and has no injury. It has high specificity and sensitivity in the diagnosis of the micro-small aneurysm It has high clinical value in the preliminary csreening of micro-smal aneurysm and evaluation.
