Fig. 2. A 70-year-old male with three hypercvascular hepatocellular carcinomas (HCCs). (A) In the early phase of computed tomography during hepatic arteriography at the time of transarterial chemoembolization (TACE), one hypercascular nodule was depicted in each of the medial segment (white arrow) in the medial segment which diagnosed as HCC. (B) Tumor staining was not obvious on angiography at proper hepatic artery. (C) For embolization planning as TACE guidance software, regions of interest (ROI) (blue circles) were set for three HCCs in order to use the automatic tumor feeding artery detection (AFD). (D) By using the AFD function, the three feeding arteries to be embolized were automatically displayed for the three ROI set as embolization targets in the 3-dimensional volume rendering image. (E) Angiography with medial segmental branch depicted two branches delineated by AFD function. Angiographically, the caudal branch (white arrow) was suspected to be involved in tumor staining, while the cephalic branch (white arrowhead) appeared to be poorly involved in tumor staining. (F) Two hyper-dense accumulations of ethiodized oil in each HCC were shown on computed tomography after TACE (white arrow and white arrowhead).
