C-arm cone-beam computed tomography (CT) with a flat-panel detector represents the next generation of imaging technology available in the interventional radiology suite and is predicted to be the platform for many of the three-dimensional (3D) roadmapping and navigational tools that will emerge in parallel with its integration. The combination of current and unappreciated capabilities may be the foundation on which improvements in both safety and effectiveness of complex vascular and nonvascular interventional procedures become possible. These improvements include multiplanar soft tissue imaging, enhanced pretreatment target lesion roadmapping and guidance, and the ability for immediate multiplanar posttreatment assessment. These key features alone may translate to a reduction in the use of iodinated contrast media, a decrease in the radiation dose to the patient and operator, and an increase in the therapeutic index (increase in the safety-vs-benefit ratio). In routine practice, imaging information obtained with C-arm cone-beam CT provides a subjective level of confidence factor to the operator that has not yet been thoroughly quantified.
配备平板探测器的C形臂锥束计算机断层扫描（CT）代表了介入放射科可用的下一代成像技术，预计它将成为许多三维（3D）路线图绘制和导航工具的平台，这些工具将随着其整合而同时出现。当前能力与尚未被充分认识的能力相结合，可能是使复杂血管和非血管介入手术的安全性和有效性得到改善成为可能的基础。这些改进包括多平面软组织成像、增强的预处理靶病变路线图绘制和引导，以及即时多平面治疗后评估的能力。仅这些关键特性就可能转化为碘化造影剂使用量的减少、患者和操作人员辐射剂量的降低，以及治疗指数的提高（安全与效益比增加）。在常规实践中，通过C形臂锥束CT获得的成像信息为操作人员提供了一种主观的置信度水平，但尚未得到充分量化。
