摘　　要：目的探讨表面遮盖重建(SSD)进行的头部CT血管成像(CTA)去骨成像技术(SSD-CTA技术)与容积CT数字减影血管造影(VCTDSA)技术对颅内动脉瘤的诊断价值。方法收集重庆医科大学附属第一医院提供的2013年4月-2014年11月期间35例利用VCTDSA技术确诊为颅内动脉瘤的患者资料,将其原始数据导入成都市第一人民医院CT工作站,进行SSD-CTA技术去骨重建,并将两组数据进行比较。另收集成都市第一人民医院2012年6月-2014年11月期间27例同时进行了SSD-CTA及数字减影血管造影(DSA)检查,并确诊为颅内动脉瘤的患者资料,将其结果进行比较。结果虽然SSD-CTA的重建图像质量评分较VCTDSA稍差,但两种技术对动脉瘤的诊断差异无统计学意义(P>0.05)。与DSA相比,SSD-CTA对于颅内动脉瘤诊断的灵敏度及特异度均为100%。结论 SSD-CTA具有临床实用价值,可作为颅内动脉瘤的检查、诊断方法。Ob）ective To investigate tile value of head boneless CT angiography （CTA） for surface shaded display （SSD） （hereinafter referred to as the SSD-CTA technology） and volume computed tomographic digital subtraction angiography （VCTDSA） in diagnosing intracranial aneurysms. Methods We collected the clinical data of 35 patients diagnosed to have intracranial aneurysm by VCTDSA between April 2013 and November 2014 from the First Affiliated Hospital of Chongqing Medical University. The original data were imported into the CT workstation of the First People＇s Hospital of Chengdu. Then, SSD-CTA technology was performed for bone reconstruction. We compared the results of these two technologies. In addition, we selected another 27 patients diagnosed with intracranial aneurism by SSD- CTA and DSA examination at the same time between June 2012 and November 2014 in the First People＇s Hospital of Chengdu for comparison. Results The quality score of SSD-CTA reconstructed image was lower than that of VCTDSA, but the diagnosis of the two technologies for intracranial aneurysm was not statistically different （P 〉 0.05）. Compared with DSA, the sensitivity and specificity of the diagnosis for intracranial aneurysms by SSD-CTA were both 100%. Conclusion SSD-CTA is valuable in diagnosing intracranial aneurvsms.
