Abstract

Objective:To evaluate the use of multi-slice spiral CT angiography(MSCTA) in the diagnosis o fmoyamoya disease.Methods:CT routine scan and MSCTA volume scanning were performed in 21 patiants.The angiograms obtained were processed on the ADW4.2 workstation to perform volume rending(VR),maximum intensity projection(MIP) and multiplanar Volume reformation(MPR).Results:In all of the 21 patients,MSCTA showed varied lesions of stenosis and obstruction in arteria carotisinterna(ICA),proximum of Willis circle and posterior and middle cerebral arteries;abnormal vessel network in the basal part of brain;and the condition of collateral circulation in the brain.Conclusion:MSCTA could well display the abnormal vessels and spatial relationship characteristic of moyamoya disease,providing important reference for the diagnosis and therapy.
