目的探讨16排螺旋CT在脑血管造影(CTA)中的临床价值。方法利用16排螺旋CT作脑血管增强扫描,后处理采用VR SSD MIP重建,本组35例,正常5例,异常30例,其中动脉瘤10例,狭窄和闭塞8例,烟雾病2例,多发动脉硬化10例。结果16排螺旋CT血管造影能显示颅内主支血管,能显示异常血管的类型、走向、位置、大小。结论16排螺旋CTA是一种无创检查方法,可作为脑血管疾病病因的筛选。 Objective To investigate the clinical value of 16-slice spiral CT in cerebral angiography (CTA). Methods CT angiography was performed with 16-slice spiral CT and post-treatment with VR SSD MIP reconstruction. The group consisted of 35 patients with normal 5 patients and 30 patients with abnormal aneurysm, including 10 aneurysms, 8 stenosis and occlusion, 2 moyamoya disease, Multiple arteriosclerosis in 10 cases. Results 16-slice spiral CT angiography can show the main intracranial vessels, showing the type, direction, location and size of abnormal vessels. Conclusion 16-slice spiral CTA is a non-invasive examination method, which can be used as a screening of the etiology of cerebrovascular disease.
