摘　　要：目的:探讨多层螺旋CT(MSCT)数字减影和常规血管造影术在颅内动脉瘤诊断中的临床应用价值。方法:回顾分析本院56例可疑颅内动脉瘤患者,应用MSCT数字减影和常规血管造影术(简称减影和常规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造影共检出动脉瘤65个,采用数字减影CTA共检出61个,敏感性为93.8%。常规CTA检出动脉瘤54个,敏感性为83.1%。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,明显优于常规CTA检查。Objective：To study the value of the application of MSCT digital subtraction CT angiography（DSCTA） and CT angiography（CTA） in the diagnosis of intracranial aneurysm.Methods：MSCT digital subtract angiography was undertaken in 56 patients who were suspected to have intracranial aneurym.Digital subtract angiography was also undertaken in all the patients.All the patients were treated by surgical operation.The two methods were compared with each other.Results：By operation and DSA,65 cases of aneurysms were found.By subtract CTA,61 cases of aneurysms were found.The sensitivity and specificity of subtract CTA were 93.8%.By conventional CTA,54 cases of aneurysm were found.The sensitiny and specificity were 83.1%.Conclusion：MSCT subtract CTA is a new modality,which is safe and has no injury.It has high specificity and sensitivity in the diagnosis of the aneurysm and obviously and is superior to CTA.
