The Value Of64-Slice Spiral CT For Diagnosis Of Hemorrhagic Moyamoya Disease

Objective：To evaluate the use of64-slice spiral CT for diagnosis Ofhemorrhagic moyamoya disease．Methods：We analyzed the clinical and imaging data of16cases withhemorrhagic Moyamoya disease retrospectively. CT routine scan of headand CTA volume scanning of head-neck were performed in allpatients．The angiography obtained were processed on the ADW4．2workstation to perform VR， MIP)and multiplanar MPR．7out of16cases were accepted DSA.Results：In all of the16patients，CTA showed varied lesions ofstenosis and obstruction in intracranial arteries(ICA) and abnormal vesselnetwork in the basal part of brain；and the condition of collateral circulationin the brain．The diagnosis of CTA were confirmed by DSA in all the7cases.Conclusion：CTA maybe a kind of preferred, quick, economic, safe,accurate and noninvasive examine.
