The steps of CBCT, EmboGuide and TACE in one of our cases. a Cone-beam CT showing enhancing HCC lesion in segment VIII, b multiplanar image centered on the lesion. c Placing circular regions-of-interest (ROIs) for the lesion. d Placing a green dot at the tip of the catheter (arrow). e The software marked two arterial feeders colored in green and red. The green feeder gives a main branch (yellow) which gives smaller branches at the lesion site. The red feeder gives a small branch at the lesion site. f Fluoroscopic image with the tip of the microcatheter at the tip of the first feeder (marked green in the previous image) with injection of a mixture of Lipiodol and chemotherapy. g Fluoroscopic image showing the mixture of Lipiodol, and chemotherapy being injected in the second feeder (marked red in the previous image). h Completion CBCT showing the HCC completely embolized. i Comparison done by the machine software between the pre- and post-embolization CBCT to assure complete embolization of the lesion
