摘要
目的探讨基于Slicer三维可视化后处理软件的3D-CTA诊断颅内破裂动脉瘤的可靠性以及准确性。方法回顾性分析2017~2018年收治的57例拟诊为颅内动脉瘤且完成CTA和3D-DSA检查的影像学资料,将CTA检查原始数据分别经传统影像工作站和Slicer后处理软件进行3D-CTA重建诊断动脉瘤,以3D-DSA为金标准。结果57例中,3D-DSA检出51例60个动脉瘤,传统影像工作站及Slicer重建的3D-CTA均检出46例54个动脉瘤。两种重建方法获得的3D-CTA对于颅内破裂动脉瘤的诊断具有相同的诊断效能(灵敏度为88.3%,特异度为85.7%),而且两种CTA后处理方法对于瘤体大小的判断无统计学差异(P>0.05)。结论基于Slicer软件获取的3D-CTA重建图像对于颅内破裂动脉瘤的诊断可靠性、准确度令人满意,可被选择作为一种颅内动脉瘤CTA图像重建方法。
Objective To evaluate the reliability and accuracy of diagnosis of ruptured intracranial aneurysms by reconstruction of 3D-CTA based on Slicer software.Methods The radiographic data of CTA and 3D-DSA in 57 patients who were were suspected with ruptured intracranial aneurysms from 2017 to 2018 were analyzed retrospectively.The original image data of the CTA was independently processed by traditional radiology workstation and Slicer software to obtain 3D-CTA images.The reliability and accuracy of detection of ruptured intracranial aneurysms by the 3D-CTA were compared with 3D-DSA serving as gold standard.Results Sixty aneurysms in 51 patiebts were detected by 3D-DSA and 46 aneurysms in 54 patients were detected by the 3D-CTA in these 57 patients.Seven aneurysms in 7 patients were missed and 1 aneurysm in 1 patient was misdiagnosed by the 3D-CTA.The sensitivity and specifity of the 3D-CTA to ruptured intracranial aneurysms were 88.3%and 85.7%,respecticely.There was no statistical difference between the aneurismal sizes including the longest diameter and radius of aneurysms judged by the two 3D-CTA reconstruction methods(P>0.05).Conclusion The reliability and accuracy of detection of ruptured intracranial aneurysms by 3D-CTA reconstructed with Slicer software is satisfied.
