Combined angiography-CT (angio-CT) systems, which combine traditional angiographic imaging with cross-sectional imaging, are a valuable tool for interventional radiology. Although cone-beam CT (CBCT) technology from flat-panel angiography systems has been established as an adjunct cross-sectional imaging tool during interventional procedures, the intrinsic advantages of angio-CT systems concerning superior soft-tissue imaging and contrast resolution, along with operational ease, have sparked renewed interest in their use in interventional oncology procedures. Owing to increases in affordability and usability due to an improved workflow, angio-CT systems have become a viable alternative to stand-alone flat-panel angiographic systems equipped with CBCT. This review aims to provide a comprehensive technical and clinical guide for the use of angio-CT systems in interventional oncology. The basic concepts related to the use of angio-CT systems, including concepts related to workflow setup, imaging characteristics, and acquisition parameters, will be discussed. Additionally, an overview on the clinical applications and the benefits of angio-CT systems in routine therapeutic and palliative interventional oncology procedures will be reviewed.

将传统血管造影成像与断层成像相结合的联合血管造影-CT（血管造影-CT）系统是介入放射学的一种有价值的工具。尽管平板血管造影系统的锥束CT（CBCT）技术已被确立为介入手术期间的辅助断层成像工具，但血管造影-CT系统在软组织成像和对比分辨率方面的固有优势，以及操作简便性，引发了人们对其在介入肿瘤学手术中应用的新兴趣。由于工作流程的改进，血管造影-CT系统的可承受性和可用性有所提高，已成为配备CBCT的独立平板血管造影系统的可行替代方案。本综述旨在为血管造影-CT系统在介入肿瘤学中的应用提供全面的技术和临床指南。将讨论与血管造影-CT系统使用相关的基本概念，包括与工作流程设置、成像特征和采集参数相关的概念。此外，还将综述血管造影-CT系统在常规治疗性和姑息性介入肿瘤学手术中的临床应用及益处。消融技术、CT血管造影、介入体部、介入肌肉骨骼、化疗栓塞、栓塞、放射治疗/肿瘤学、腹部/胃肠道、骨骼轴位 © RSNA，2021年
