摘要
目的 探究基于3D-Slicer后处理CT血管造影(CTA)在颅内动脉瘤夹闭术后复查中的应用价值。方法 回顾性收集57例动脉瘤夹闭术患者的术后CTA影像资料,图像后处理方法包括多平面重组(MPR)、容积再现(VR)及最大密度投影重组(MIP),并与放射科工作站处理结果进行定性、定量对比,评价其临床应用价值。结果 57例患者69个动脉瘤共夹闭63个,术后CTA除5例图像质量不佳,余均可轻清晰显示瘤夹位置、残余瘤体、载瘤动脉瘤通畅性;术后CTA见2例夹闭不全,2例新发动脉瘤,9例血管广泛痉挛显影浅淡;脑出血3例,脑积水5例,脑梗死1例,以上结果与放射科工作站一致。两种方法重建3D-CTA对于夹闭后载瘤动脉瘤管径大小呈现无统计学差异,且一致性高。结论 3D-Slicer软件对于夹闭术后CTA的图像后处理结果令人满意,可作为一种备选的工具服务于临床。
Objective To explore the value of CT angiography(CTA)reconstruction based on 3D-Slicer in evaluating intracranial aneurysms after Clipping.Methods The imaging materials of 57 patients with intracranial aneurysm after treatment with nenrosurgical clipping were retrospectively analyzed.MPR,VR and MIP techniques proessed by 3D-Slicer were used to evaluate the postoperative intracranial aneurysms,which is compared with radiology workstations to evaluate its clinical application value in qualitative and quantitative way.Results There were altogether 69 intracranial aneurysms in these 57 patients.63 aneurysms had aneurysm clipping operation performed.In addition to poor image quality in 5 patients of postoperative CTA,the remaining clearly reveal the position of the clip,relationship between the parent artery and aneurysm clips,whether the parent artery was smooth or not,aneurysm neck residual and recurrent.Postoperative CTA showed residual neck in 2 case,recurrent in 2 case,cerebral vasospasm in 9 case,and hemorrhage in 3 case,hydrocephalus in 5 case,Cerebral infarction in 1cas.The above results are consistent with the radiology workstation.There was no statistical difference in the diameter of the tube,and the consistency was high.Conclusion CTA reconstruction based on 3D-slicer software is satisfactory for post-operative follow-up of patients with the aneurysms treated with clipping,it can be used as an alternative tool for CTA reconstruction.
