Cone-beam CT (CBCT) is generated during a rotational sweep of the C-arm around the patient, and can be a valuable imaging technique, providing in situ cross-sectional imaging. It is easy to evaluate the morphologic characteristics of hepatic arteries from multiple views with the use of various reconstruction techniques, such as maximum intensity projection (MIP) and volume rendering. CBCT angiography is capable of providing more information than the standard 2-dimensional angiography in visualizing hepatocellular carcinomas (HCCs) and targeting tumors though precise microcatheter placement in close proximity to HCCs. It can also be useful in evaluating treatment success at the time of the procedure. It is anticipated that CBCT could reduce radiation exposure, the overall procedure time and contrast material use because it allows immediate feedback for an efficient angiographic procedure. Therefore, CBCT angiography is an exciting technology with the potential to significantly impact the practice of interventional radiology. The purpose of this article is to provide a review of the principles, clinical applications and technique of CBCT angiography for HCC treatment.
锥形束CT（CBCT）是在C形臂围绕患者进行旋转扫描时生成的，它可以成为一种有价值的成像技术，提供原位横断面成像。使用各种重建技术，如最大强度投影（MIP）和容积再现，从多个视角评估肝动脉的形态特征很容易。CBCT血管造影在可视化肝细胞癌（HCC）以及通过将精确的微导管放置在靠近HCC的位置来靶向肿瘤方面，能够提供比标准二维血管造影更多的信息。它在评估手术过程中的治疗效果时也可能有用。预计CBCT可以减少辐射暴露、缩短整个手术时间并减少造影剂的使用，因为它允许对高效的血管造影手术进行即时反馈。因此，CBCT血管造影是一项令人兴奋的技术，有可能对介入放射学的实践产生重大影响。本文的目的是对用于HCC治疗的CBCT血管造影的原理、临床应用和技术进行综述。
