Clinical Study

Comparison of the Number of Image Acquisitions and Procedural Time Required for Transarterial Chemoembolization of Hepatocellular Carcinoma with and without Tumor-Feeder Detection Software

Figure 1

Images from a patient with hepatocellular carcinoma undergoing transarterial chemoembolization with the assistance of automated feeder-vessel detection software. (a) The common hepatic artery angiogram shows the target tumor (arrow) at the right hepatic dome. Identifying the complex arterial vasculature of the tumor feeder is difficult. (b) The volume-rendered C-arm computed tomography (CT) image, showing the extracted tumor feeder by the software as a path from the catheter to the target (arrow) indicated in green. (c) Selective catheterization directly into the suggested feeder artery, based on the software analysis, shows tumor enhancement (arrow). (d) The axial C-arm CT image, obtained during contrast injection from the same feeder artery, confirms target enhancement (arrow) in association with the treatment area.
