　　目的探讨16层螺旋 CT 血管造影（CTA）对脑血管病变的诊断价值。方法使用16层螺旋 CT 对80例患者行 CT 检查，其中CTA 显示正常表现者12例，脑血管病变68例；扫描数据在工作站进行容积再现（VR）、最大密度投影（MIP）、多层平面重建（MPR）、表面遮盖显示（SSD)等技术后处理。结果12例 CTA 表现正常者均能显示 Willis'环及大脑前、中、后动脉主干及其4级以上分支的血管，68例脑血管病变中能清楚显示病变的位置、大小、形态及与周围血管和颅骨的关系，诊断明确。结论16层螺旋 CT 血管造影可作为脑血管疾病诊断首选的筛查方法。

Objective To evaluate the value of 16-slice spiral CT angiography in the diagnosis of cerebrovascular diseases. Methods 80 patients were examined with 16-slice spiral CT, CTA showed that normal in 12 cases and cerebrovascular diseases in 68 cases. The data post-processing was performed by volume rendering (VR), maximum intensity projection (MIP), multi-planar reconstruction (MPR), and shaded surface display (SSD). Results The imaging could show the Circle of Willis, the arterial trunk of anterior, middle and posterior cerebral artery and its fourth grade or over vessel branches in normal 12 patients; then in the 68 patients with cerebrovascular diseases, the imaging could show clearly the location, size, of shape the lesions and the relationship with the surrounding vessels and skull. Conclusion 16-slice spiral CT angiography can be the first choice of screening for cerebrovascular diseases.
