RESUMO
@# Objective To explore the application of 64-slice spiral CT angiography (CTA) in the evaluation of cerebral vascular disease. Methods 160 cases with suspected cerebral vascular disease underwent CTA with 64-slice spiral CT. Two dimensional and three dimensional reformation were performed in all cases including multiplanar reconstruction (MPR), maximum intensity projection (MIP), volume rendering (VR). Both axial and reformatted images were analyzed by two radiologists. Results 94 cases of 160 were diagnosed as abnormal, including 50 stenosis or obstructive disease, 21 aneurysm, 1 post-intravascular stent, 4 cliped aneurysm, 3 arteriovenous malformation, 4 moyamoya disease, 4 carotid-cavernous fistula, 4 venous sinus thrombus, 1 straight sinus occlusion with perpetual falcial sinus, 1 great cerebral venous aneurysm, 1 perpetual sublingual artery. Conclusion 64-slice spiral CTA is a valuable diagnostic method for various cerebral vascular disease.
