Title: Application of Multi-slice Spiral CT in the Diagnosis of Moyamoya Disease
Abstract: Objective To evaluate the value of 16-slice Spiral CT angiography(M empirical study of SCTA) and reconstruction in the diagnosis and therapy of moyamoya disease.Material and methods 15 patiants with moyamoya disease were examined both with routine CT scanning and MSCTA,all performed Volume Rending(VR)、Maximum density projection(MIP) and Multiplanar reconstruction(MPR) with ADW4.2 software.Results In all cases CTA showed the stenosis or obstruction of arteria carotis interna(ICA) or proximum of Wills circle,abnormal vessel network in brain basal part.Including stenosis of bilateral ICA(6cases),one side ICA and posterior cerebral artery(1 case),one side middle cerebral artery(8 cases).The branch vessels could been evaluated with CTA images.VR was better on showing the stenosis of the vessels and its spatial relation with surrounding bone structure,MIP and MPR was better on showing abnormal vessel network in brain basal part and branch vessels.Conclusion With different reconstruction,MSCTA can display the abnormal vessels and spatial relation very well,and provide important reference for the therapy.
