目的探讨16层螺旋CT血管造影(CTA)对颅内动脉瘤的诊断价值。方法28例疑有颅内动脉瘤患者均行16层CTA和DSA检查,对CTA的表现结合DSA和手术结果进行回顾性分析。结果本组28例经CTA共检出动脉瘤27个,其中25个经手术和DSA证实。1例CTA显示动脉瘤2个,DSA只显示1个,另1例CTA显示可疑动脉瘤2个,DSA显示正常。16层CTA诊断颅内动脉瘤的敏感性为89.2%,特异性为100%,准确性为96.4%。结论16层CTA在显示颅内动脉瘤方面可与DSA媲美,有重要临床应用价值。
Objective To investigate the diagnostic value of 16-slice spiral CT angiography (CTA) for intracranial aneurysms. Methods Twenty - eight patients with suspected intracranial aneurysm underwent 16 - slice CTA and DSA examinations. The clinical manifestations of CTA combined with DSA and surgical findings were retrospectively analyzed. Results A total of 27 aneurysms were detected in 28 patients by CTA, of which 25 were confirmed by surgery and DSA. One case of CTA showed 2 aneurysms, 1 showed DSA, 2 showed suspicious aneurysms in another case, and DSA showed normal. The sensitivity and specificity of 16-slice CTA for the diagnosis of intracranial aneurysms were 89.2%, 100% and 96.4% respectively. Conclusion 16-slice CTA is comparable to DSA in displaying intracranial aneurysms and has important clinical value.
