Fig. 5. Illustrations showing difference in tumor feeder structure. When a trunk artery diverges into several similar size arteries, lipiodol droplets are fragmented at the diverging point (A). Thus, lipiodol droplets could flow into the tumor feeders. When ‘ small tumor feeders branch out from a large trunk artery, lipiodol droplets could not be fragmented due to its surface tension, nor could not flow into the small tumor feeders (B).
