Follow-up examinations using magnetic resonance imaging or digital subtraction angiography are mandatory after flow diverter treatment of cerebral aneurysms. However, flow diverter features metal artifacts on magnetic resonance imaging and ischemic complications with digital subtraction angiography. Ultra-high-resolution computed tomography systems have recently become available in clinical practice. The combined use of ultra-high-resolution computed tomography and a reconstruction technique called model-based iterative reconstruction is expected to replace follow-up magnetic resonance imaging and digital subtraction angiography of flow diverter placement. Here, we report a case of ultra-high-resolution computed tomography with model-based iterative reconstruction after flow diverter treatment.
脑动脉瘤血流导向治疗后，必须使用磁共振成像或数字减影血管造影进行随访检查。然而，血流导向装置在磁共振成像上有金属伪影，数字减影血管造影则有缺血性并发症。超高分辨率计算机断层扫描系统最近已在临床实践中可用。超高分辨率计算机断层扫描与一种称为基于模型的迭代重建的重建技术联合使用，有望取代血流导向装置置入后的随访磁共振成像和数字减影血管造影。在此，我们报告一例血流导向治疗后使用基于模型的迭代重建的超高分辨率计算机断层扫描病例。
