Abstract

Automated feeder detection software of Canon Medical Systems (Embolization Plan: EP) uses computed tomography (CT) images to identify feeding arteries. Compared to AFD using cone beam CT images, EP can utilize various kinds of CT images without depending on the imaging equipment, making it extremely versatile. After marking tumors and the virtual catheter tip on CT images, EP automatically detects the feeders and displays them on volume rendering (VR) and multiplanar reconstruction (MPR) images. With EP, feeder analysis can be performed simultaneously for up to 10 lesions, and the time from CT acquisition to feeder analysis is approximately within 5 minutes. The feeder identification rate of EP in our hospital is about 80-90% at the sub-subsegmental branch level in transcatheter arterial chemoembolization (TACE), and almost 100% at the lobar artery level in renal artery embolization (RAE). In the future, it is expected that virtual embolized area prediction, and analysis using transvenous CT angiography will be possible.
