“双血管三维影像融合”对脑血管病诊治评估的价值

目的 探讨“双血管三维影像融合”技术的影像融合方法及其在脑血管病诊断和治疗中的应用价值。方法 应用西门子Artis zee biplane双平板DSA机及其所配设备System syngo X-WP三维后处理工作站，双容积重建出数据，利用Inspace-3D3D-Fusion软件分析合并数据，显示两侧颈内动脉或一侧颈内动脉和椎动脉与血管病变的供血关系。结果 利用软件能显示双血管供血病变（如脑动静脉瘘、脑动静脉畸形等），清晰显示血管病变与供血动脉、走向等关系，帮助诊断和指导治疗。结论 “双血管三维影像融合”对诊断脑血管病血供情况和指导治疗有较大临床价值，并且利用融合Fusion技术改进重建工作流程，因此可以大大扩展双血管融合技术的临床适应症，提高显示的准确性，是判断Willis环的结构和双血管供应的血管病变的新方法，对临床诊断、治疗有重要参考价值，对科研与教学增加了新的评估手段与直观方法。

Evaluation of diagnosis and treatment of cerebrovascular disease by "dual vessel 3D imaging fusion" technique

Objective To evaluate the application of "dual vessel three-dimensional (3D) imaging fusion" technique to diagnosis and treatment of cerebrovascular disease. Methods The dual vessel 3D imaging fusion technique were performed for diagnosis and treatment of 6 cases of cerebrovascular disease including 1 case of anterior communicating artery arteriovenous fistula, 1 anterior communicating artery aneurysm, 1 posterior communicating artery aneurysm, 2 dural arteriorvenous fistulae in the anterior cerebral fossae and 1 parieto-occipital arteriovenous malformation. Application of Siemens Artis zee biplane DSA and the 3D post-processing workstation of System syngo X-ray WP to reconstruction data by Dual-volume and analysis by Inspace-3 D imaging fusion software showed the relationship around double brain blood vessels and other organizations. Results The vascular lesions including the aneurysm, arteriovenous fistulae and arteriovenous malformation fed blood to by the dual vessels, the relationship of the vascular lesions with the vessels feeding blood to the lesions and their runs were clearly shown by "dual vessel 3D imaging fusion" technique. The diagnosis of the cerebraovascular lesions were definitely made and the lesions were successfully embolized. Conclusions "Dual vessel 3D imaging fusion" technique is greatly helpful to the diagnosis and treatment of cerebrovascular disease supplied blood by dual vessels and therefore should be clinically spread.
