RESUMO
Objective To evaluate the application of multi-slice CT angiography(MSCTA) in cerebral vascular diseases.Methods 16-slice spiral CT angiography of 32 patients which clinically suspected cerebrovascular diseases were analyzed retrospectively.Source images were processed by GE Lightspeed CT Scanner;all axial images were transferred to an external workstation.The reconstructed images were processed VR,MPR,MIP in working-station.Results 10 of the 32 patients were normal, 17 were aneurysms,could be clearly displayed with the source, size,and neck width.3 were AVM,the location and scope could be observed.2 were vaso-occlusive.Conclusion Multislice spiral CT angiography is a safe ,quick and noninvasive method in diagnosing the cerebrovascular disease,it may be proposed as a first choice technique for screening and preoperative assessment for cerebrovascular disease.CTA is a valuable diagnostic method for various intracranial cerebral disease.
