Efficacy of intra-arterial contrast-enhanced ultrasonography during transarterial chemoembolization with drug-eluting beads for hepatocellular carcinoma

Figure 1 Patient flow diagram. In this diagram, treatment response evaluated by contrast-enhanced ultrasonography (CEUS) and/or dynamic computed tomography (CT) immediately, one month and six months after DEB-TACE for hepatocellular carcinoma (HCC) using mRECIST. Findings on CEUS or dynamic CT were evaluated using mRECIST criteria. ¹Complete treatment: Disappearance of the tumor enhancement after DEB-TACE by IAUS findings; ²Incomplete treatment: Presence of residual tumor enhancement after DEB-TACE by IAUS findings. CR: Complete response; PR: Partial response; SD: Stable disease; PD: Progressive disease.
