摘要:

［目的］ 探讨16层螺旋血管成像技术（CTA）在诊断颅内动脉瘤方面的临床应用价值。［方法］ 对30例疑有颅内动脉瘤患者行16层螺旋CT脑血管造影检查，层厚0.625 mm ，应用后处理技术三维重建。［结果］30例患者患颅内动脉瘤18例，动静脉畸形2例，烟雾病1例，9例正常。10例动脉瘤患者同时行脑血管DSA检查，与CTA检查结论一致。 ［结论］ 16层螺旋CTA能准确诊断颅内动脉瘤，为临床提供精确的诊疗信息。

Abstract:

［Objetive］ To evaluate 16-slice CTA to diagnose cerebral aneurysms in clinical practice. ［Methods］ Using 0.625 mm slice thickness ,16-slice CT cerebral angiography was performed in30 patients with suspected cerebral aneurysms.3D reconstruction，including after-finishing Carried out .image quality was evaluate. ［Result］ In all patients,which included cerebral aneurys ms(n=18) arteriovenous malformations(AVM,n=2) ,Moyamoya disease (n=1) and normal findings (n=9).Tew patients with diagnose cerebral aneurysms to carry out DSA angiography,the diagnoses were proved by DSA.［Conclusion ］16-slice CT can exact diagnose cerebral aneurysms,providing clinicians with precise diagnose and treat information.
