Diagnoses Evaluation of 64-slice Spiral CT Angiography in Cerebral Vascular Lesions / 医疗卫生装备

ABSTRACT

Objective To explore the diagnosis evaluation of 64-slice spiral CT angiography(CTA) in cerebral vascular disease.Methods 64-slice spiral CT angiography of 48 patients with suspected clinically cerebral vascular diseases were analyzed retrospectively.The source images were got by TOSHIBA Aquilion VCT Scanner,and all axial images were transferred to an external workstation.The reconstructed images were processed into volume rendering(VR),multiplanner reconstruction(MPR) and maximum intensity projection(MIP),the values were valuably compared with the results of surgery or DSA.Results 30 cases were aneurysms,4 cases were AVM,8 cases were cerebral artery stenosis or occlusion,6 cases were normal.Conclusion The 64-slice spiral CTA is a valuable diagnostic method for various cerebral vascular diseases.
