C形臂计算机断层扫描（C形臂CT）代表了血管造影套件中可用的下一代成像技术，预计将成为许多三维（3D）道路测绘和导航工具的平台，这些工具将与其实施结合出现。目前和未被认可的能力的结合可能是复杂肝血管介入手术安全性和有效性改善的基础。这些改进包括多平面软组织成像、治疗前靶病变血管路线图以及立即治疗后评估的能力。除了增加治疗指数（安全性与受益比增加）外，这些关键特征本身可能会降低操作员使用的碘化造影剂的利用率，以及降低患者和操作员的辐射剂量。在常规实践中，使用C形臂CT获得的成像信息为操作员提供了尚未量化的主观置信度。Tech Vasc Interventional Rad 10：79-86（C）2007 Elsevier Inc.

C-arm computed tomography (C-arm CT) represents the next generation of imaging technology available in the angiography suite that is predicted to be the platform for many of the three-dimensional (3D) road mapping and navigational tools that will emerge in conjunction with its implementation. The combination of current and unappreciated capabilities may be the foundation on which improvements in both safety and effectiveness of complex hepatic vascular interventional procedures become possible. These improvements include multi-planar soft tissue imaging, pretreatment target lesion vascular road mapping, and the ability for immediate posttreatment assessment. These key features alone may translate into a reduction in the utilization of iodinated contrast used by the operator, as well as a decrease in the radiation dose to the patient and the operator, in addition to increasing the therapeutic index (increase in the safety versus benefit ratio). In routine practice, imaging information obtained with C-arm CT provides a subjective level of confidence factor to the operator that has not yet been quantified.
