Abstract:
Objective To evaluate the technique of multi-slice spiral CT angiography and it's value in diagnosing cerebrovascular diseases.Methods 77 cases were studied with GE Discovery Ultra 16-slice spiral CT scanner.The raw data were then transferred to ADW4.1 workstation and reconstructed with Volume Rendering(VR) and Maxium intensity projection(MIP)and Multiplanner Reconstraction(MPR).Results In 77 cases,49 were aneurysms,19 were AVM,7 were vaso-occlusive,2 were Moya-moya disease.Cerebrovascular was dispayed clearly in VR MIP and MPR.The images acquired with VR were more colorful and spatial than MIP and MPR,but the diagnosis value of MIP and MPR were higher.Conclusion MSCTA is an available noninvasive method in diagnosing the cerebrovascular disease.It could define character and position.MSCTA is an effective method and can be an nalterntive of DSA partially.
