目的从病灶检出及血管构筑显示方面探讨320排CT四维CT血管造影(4D-CTA)在脑动静脉畸形(CAVM)诊断中的临床应用价值.方法对20例可疑CAVM患者行4D-CTA成像和数字减影血管造影(DSA)检查.比较两种成像方法所示畸形血管团位置、数目、大小及供血动脉来源、引流静脉深浅、数目方面的差异.结果 20例患者经4D-CTA诊断为CAVM,其中1例经DSA证实为脑动静脉瘘(CAVF);4D-CTA对畸形血管团位置、数目、大小,供血动脉及引流静脉的显示与DSA所示一致性良好,差异均无统计学意义(P＞0.05).结论 4D-CTA能实现颅内血流状态的无创性动态显示,在CAVM的诊断及治疗策略制定上具有重要价值.

Objective To discuss the value of 4D-CTA using 320-row area detector in diagnosis of cerebral arteriovenous malformations (CAVMs) from the aspects of nidus detection and angioarchitecture.Methods 20 suspected CAVM patients were enrolled.4D-CTA was performed before digital silhouette angiography (DSA).Location and size of niduses and numbers of feeding arteries and draining veins shown in this two imaging methods were Abserved.Results All patients were diagnosed as CAVMs by 4D-CTA and 1 case was confirmed as arteriovenous fistula by DSA.In this 19 CAVMs,the location and size of nidus and the numbers of feeding arteries and draining veins shown by 4D-CTA were sufficiently accurate when compared to DSA (P ＞ 0.05).Conclusions Non-Invasive 4D-CTA was able to detect CAVMs and display the dynamic blood flow.It can be a useful option in the diagnosis of CAVMs.
