Background/Objectives: Hybrid Angio-CT suites have emerged in response to the growing demands for innovation and procedural complexity in minimally invasive therapies. It is hypothesized that enhanced image guidance capabilities enabled by multimodality imaging can improve procedural safety, accuracy, and efficacy. However, due to the current lack of sufficient data to support a systematic review, the objective of this article is to present a comprehensive synthesis of the existing literature through a narrative review. Methods: This narrative review is based on purposefully identified research reports, their critical evaluation, and synthesis by a group of experienced users. The analysis covers three key areas: (1) current state of available technologies and functionalities, (2) novel perspectives through ‘Direct Intravascular Contrast media Injection CT’ (DICI-CT), and (3) the role of Angio-CT in established and emerging image-guided procedures. Results: The review presents typical configurations and room layouts for Angio-CT systems and discusses further technological improvement potential. Selected literature is complemented by expert experience to report on the current state of the art and demonstrate its use and efficiency. Based on our expert experience, it is demonstrated how DICI-CT can be used to reduce contrast dose and improve lesion visualization, targeting, and endpoint determination. Furthermore, in this review the advantages, including survival benefit (i.e., in trans-arterial chemoembolization and in blunt trauma) and cost-effectiveness (i.e., in emergency care), are reviewed with reference to oncologic and non-oncologic applications in both elective and emergency medicine. Conclusions: Hybrid Angio-CT suites can provide significant additional imaging information with the potential to improve image-guided procedures. This perspective is increasingly supported by retrospective data in interventional oncology and beyond. Provided that further technological advancements are achieved and prospective clinical data substantiates the anticipated clinical and economical benefits, hybrid Angio-CT suites are anticipated to play a key role in the multimodality interventional suite of the future.
背景/目的：随着微创治疗领域对创新和手术复杂性的需求日益增长，混合式血管造影-CT复合手术室应运而生。多模态成像技术有望通过增强影像引导能力，提升手术安全性、精确性和有效性。然而，由于目前缺乏足够数据支持系统性综述，本文旨在通过叙述性综述对现有文献进行全面整合分析。方法：本综述基于有针对性筛选的研究报告，由经验丰富的使用者团队进行批判性评估与综合论述。分析涵盖三个关键领域：(1)现有技术与功能的发展现状，(2)通过"直接血管内造影剂注射CT成像"技术带来的新视角，(3)血管造影-CT在成熟及新兴影像引导手术中的作用。结果：综述展示了血管造影-CT系统的典型配置与手术室布局，并探讨了技术改进潜力。通过专家经验补充的文献分析，报告了当前技术发展水平并论证了其应用效能。基于专家经验，论证了直接血管内造影剂注射CT成像技术如何实现造影剂减量，同时改善病灶可视化、靶向定位及终点判定。此外，本综述结合肿瘤与非肿瘤领域的择期与急诊医学应用，系统分析了该技术的优势，包括生存获益（如经动脉化疗栓塞术和钝性创伤治疗）与成本效益（如急诊救治）。结论：混合式血管造影-CT复合手术室能提供重要的补充影像信息，具有优化影像引导手术的潜力。介入肿瘤学及其他领域的回顾性数据日益支持这一观点。若未来能实现技术突破并获得前瞻性临床数据证实其预期临床与经济效益，混合式血管造影-CT复合手术室有望在多模态介入手术体系中发挥关键作用。
