Selective TACE for hepatocellular carcinoma using cone beam CT on a flat detector angiography system: initial experience

Transcatheter arterial chemoembolization (TACE) is widely performed for unresectable hepatocellular carcinoma [1-6]. Recent meta-analysis of previous randomized controlled trial data of TACE for hepatocellular carcinoma reported that TACE could improve the survival rate [3, 4]. Selective TACE should be performed if possible, in order to avoid toxicity to the surrounding non-cancerous hepatic parenchyma. Matsui et al. [5] and Takayasu et al. [6] reported that subsegmental TACE could improve local control as well as the survival rate.
