Summary

Transarterial chemoembolization (TACE) is the most performed endovascular interventional radiology (IR) procedure. TACE procedures are performed in an IR suite, most of which are equipped with floor-based flat-panel robotic C-arm allowing two-dimensional imaging. Cone-beam computed tomography (CBCT) has been developed to allow three-dimensional navigation but has several limitations such as reduced signal to noise ratio and small field-of-view, and seems to have negative impact on patient radiation exposure. Another option to perform 3D imaging is called angio-CT which combines a CT-scan and a floor-based flat-panel robotic C-arm in a single IR suite. Even if some publications have shown benefit of angio-CT in TACE procedures in Japan, no study about angio-CT in liver IR procedures has been conducted in the occidental world so far. The purpose of our study was to assess the impact of angio-CT use on patient radiation exposure and treatment quality in TACE procedures compared to CBCT. This before-after study consisted of a review of consecutive TACE procedures performed between January 2016 and September 2017 in our institution with two different imaging modalities, defining two study groups (C-arm with CBCT versus angio-CT).
