Transportation of patients requiring multiple diagnostic and imaging-guided therapeutic modalities is unavoidable in current radiological practice. This clinical scenario causes time delays and increased risk in the management of stroke and other neurovascular emergencies. Since the emergence of flat-detector technology in imaging practice in recent decades, studies have proven that flat-detector X-ray angiography in conjunction with contrast medium injection and specialized reconstruction algorithms can provide not only high-quality and high-resolution CT-like images but also functional information. This improvement in imaging technology allows quantitative assessment of intracranial hemodynamics and, subsequently in the same imaging session, provides treatment guidance for patients with neurovascular disorders by using only a flat-detector angiographic suite-a so-called one-stop quantitative imaging service (OSIS). In this paper, we review the recent developments in the field of flat-detector imaging and share our experience of applying this technology in neurovascular disorders such as acute ischemic stroke, cerebral aneurysm, and stenoocclusive carotid diseases.
在当前放射学实践中，需要多种诊断和影像引导治疗方式的患者的转运是不可避免的。这种临床情况导致了在管理中风和其他神经血管急症时的时间延迟和风险增加。自近几十年来成像实践中平板探测器技术的出现以来，研究已经证明，平板探测器 X 射线血管造影术结合造影剂注射和专门的重建算法不仅可以提供高质量和高分辨率的 CT 样图像，还可以提供功能信息。这种成像技术的改进允许对颅内血流动力学进行定量评估，并且随后可以在同一成像会话中，通过仅使用平板探测器血管造影套件（即所谓的一站式定量成像服务（OSIS））为患有神经血管疾病的患者提供治疗指导。在本文中，我们回顾了平板探测器成像领域的最新发展，并分享了我们在急性缺血性中风、脑动脉瘤和狭窄性颈动脉疾病等神经血管疾病中应用该技术的经验。
