[目的]探讨16层螺旋血管成像技术(CTA)在诊断颅内动脉瘤方面的临床应用价值。[方法]对30例疑有颅内动脉瘤患者行16层螺旋CT脑血管造影检查,层厚0.625 mm,应用后处理技术三维重建。[结果]30例患者患颅内动脉瘤18例,动静脉畸形2例,烟雾病1例,9例正常。10例动脉瘤患者同时行脑血管DSA检查,与CTA检查结论一致。[结论]16层螺旋CTA能准确诊断颅内动脉瘤,为临床提供精确的诊疗信息。
[Objective] To explore the clinical value of 16-slice spiral CT angiography (CTA) in the diagnosis of intracranial aneurysms. [Methods] Totally 30 patients with suspected intracranial aneurysm underwent 16-slice spiral CT angiography. The thickness of the layer was 0.625 mm. Three-dimensional reconstruction was performed by post-processing technique. [Results] There were 18 cases of intracranial aneurysm, 2 cases of arteriovenous malformation, 1 case of moyamoya disease and 9 cases normal in 30 cases. Ten patients with aneurysm at the same time cerebral vascular DSA examination, consistent with the CTA examination. [Conclusion] 16-slice spiral CTA can accurately diagnose intracranial aneurysms and provide accurate clinical diagnosis and treatment information.
