Abstract

Objective To evaluate the clinical application and value of 16-detector spiral CT dual-phase angiography in the diagnosis of cerebral arteriovenous malformation.Methods The manifestation of 16-detector spiral CT dual-phase angiography were retrospectively analyzed in 35 cases with cerebral arteriovenous malformation(AVM).Results Arterial phase CTA displayed well AVM's affording arteria,vascular malformation and part of early draining vein,and venous phase CTA displayed AVM's affording arteria,vascular malformation and expanded draining vein.Conclusion 16-detector spiral CT dual-phase angiography can clearly show imaging characteristics of cerebral arteriovenous malformation,and it is a reliable diagnostic method of AVM.
