“…C-arm cone-beam computed tomography (CBCT) is a new imaging technology that enables acquisition of cross-sectional imaging with modern angiographic systems equipped with a flat panel detector [9]. Volumetric tomographic images can be combined and co-displayed with conventional 2D angiographic imaging and dedicated software during interventional procedures to plan treatment, navigate/position the catheter or device, monitor the treatment, and assess the final result or verify margins.…”

C-arm cone-beam computed tomography (CBCT) is a new imaging technology integrated in modern angiographic systems. Due to its ability to obtain cross-sectional imaging and the possibility to use dedicated planning and navigation software, it provides an informed platform for interventional oncology procedures. In this paper, we highlight the technical aspects and clinical applications of CBCT imaging and navigation in the most common loco-regional oncological treatments.

Cone-beam computed tomography (CBCT) is an imaging technique that provides computed tomographic (CT) images from a rotational scan acquired with a C-arm equipped with a flat panel detector. Utilizing CBCT images during interventional procedures bridges the gap between the world of diagnostic imaging (typically three-dimensional imaging but performed separately from the procedure) and that of interventional radiology (typically two-dimensional imaging). CBCT is capable of providing more information than standard two-dimensional angiography in localizing and/or visualizing liver tumors (“seeing” the tumor) and targeting tumors though precise microcatheter placement in close proximity to the tumors (“reaching” the tumor). It can also be useful in evaluating treatment success at the time of procedure (“assessing” treatment success). CBCT technology is rapidly evolving along with the development of various contrast material injection protocols and multiphasic CBCT techniques. The purpose of this article is to provide a review of the principles of CBCT imaging, including purpose and clinical evidence of the different techniques, and to introduce a decision-making algorithm as a guide for the routine utilization of CBCT during transarterial chemoembolization of liver cancer.

“…CT needs rotation and z-direction translation of the source detector system to produce axial images of the target anatomical section. Meanwhile, C-arm CBCT allows entire volumetric data acquisition in a single rotation [34], thus shortening the time to image construction and minimizing risks associated with procedures, including the duration of the procedure, e.g., moving patients to a CT scanner in a unit without dedicated interventional radiology facilities. Although CT fluoroscopy may be a good alternative that would overcome the lack of real-time CT guidance, it requires more dedicated facilities and may also increase patient and operator exposure to radiation as compared to that associated with use of C-arm CBCT combined with ultrasound guidance.…”

Objective: To assess the usefulness of C-arm cone beam computed tomography (CBCT) combined with ultrasound for the treatment of hepatocellular carcinoma (HCC) by radiofrequency ablation (RFA). Methods: Patients underwent RFA following transcatheter arterial chemoembolization (TACE) or RFA alone under ultrasound or CBCT guidance combined with ultrasound-based techniques. They were divided into 2 groups based on the use (C group) and nonuse (NC group) of CBCT guidance. The technical success of RFA and local tumor progression after the first RFA session were evaluated by dynamic contrast-enhanced imaging methods. Between-group differences were assessed retrospectively. Results: We enrolled 198 patients with 260 HCC nodules. The complete ablation rates were 63.0 and 89.4% in the NC and C groups, respectively. In log-rank testing, local tumor progression occurred significantly more often in the NC group when RFA was used without TACE, in males when des-gamma-carboxy prothrombin was ≥29 mAU/mL, and when the diameter of a nodule was ≥18 mm. On Cox proportional-hazards regression analysis, the NC group, RFA alone without TACE, and male gender were significant independent variables. Conclusion: TACE followed by RFA under CBCT and ultrasound guidance improves the reliability of ablation of target HCC nodules, reduces the need for additional treatment sessions, and prevents local tumor progression.
