Figure 8. — Usefulness of transarterial chemoembolization (TACE) guidance software for hepatocellular carcinoma in the caudate lobe.

A. T2-weighted MRI shows a tumor in the caudate process of the caudate lobe (arrow). B. Common hepatic arteriogram shows a tumor stain (arrow) and tumor-feeding branch (arrowhead), but the origin of the tumor feeder is unclear. C. TACE guidance software identifies the tumor feeder arising from the posterior segmental artery of the right hepatic artery. D. The branch was selectively embolized. The arrow indicates the tumor. E. Unenhanced CT performed 1 week after TACE shows dense iodized oil accumulation in the tumor. F. Arterial-phase CT performed 3 months after TACE shows no tumor recurrence.
