Arterial phase of contrast-enhanced CT before (a, b, c, d) and after (e, f, g, h) BOAI-TACE in a 78-year-old man. Seven HCCs were found in the liver, including a 14 mm hepatocellular carcinoma (HCC) in S3 (arrow), a 13 mm HCC in S4/8 (white arrowhead), a 11 mm HCC in S8/5 (curved arrow), and a 6 mm HCC in S5 (black arrowhead). After treatment, the contrast effect of all lesions disappeared and complete response was obtained.
