摘　　要：目的通过对颅内动脉瘤的主要的影像学检查方法(CTA和DSA)的临床比较,探讨二者在对颅内动脉瘤的诊断以及治疗中的应用价值。方法对某院收治的172例颅内动脉瘤患者运用CTA以及DSA进行检查,并对二者的影像学检查结果与治疗中发现的动脉瘤的大小、形状等进行比较。结果 CTA与DSA在对颅内动脉瘤的检查中,在灵敏度、显影、瘤颈/瘤体比以及检出个数的比较中差异无统计学意义(P﹥0.05),在相关并发症以及检查的最小动脉瘤直径中差异有统计学意义(P﹤0.05)。结论 DSA可以较好的显示动脉瘤的大小、形态等,CTA可以对动脉瘤周围组织进行三维重建,提供其三维形态。OBJECTIVE To explore the intracranial aneurysm on the main imaging method（CTA and DSA）in clinic,and compare the two intracranial aneurysms in the diagnosis and treatment of intracranial aneurysms.METHODS 172 patients with intracranial aneurysms were diagnosed by using CTA and DSA,the size and shape comparison of the results were compared.RESULTS For the CTA and DSA in diagnosis of intracranial aneurysms,there was no significant difference in the sensitivity,contrast and aneurysm neck/tumor ratio（P﹥0.05）,there are significant difference in the complication and aneurysm Diameter（P﹤0.05）.CONCLUSION DSA can better show the aneurysm size and morphology,CTA aneurysms can be three-dimensional reconstruction of the surrounding tissue,provide the treatment effect of the three dimensional shape,joint Inspection could improve the treatment of intracranial aneurysms.
