The purpose of this study was to investigate the value of carbon dioxide‐enhanced ultrasonography (CO 2 ‐US) in the evaluation of viable hepatocellular carcinomas (HCC) which were treated by transcatheter arterial embolization (TAE), percutaneous ethanol injection (PEI), or a combination treatment (TAE and PEI). Forty‐one patients with 66 HCC were included in the study. They underwent CO 2 ‐US and angiography were performed in all tumours after they were treated by TAE, PEI or a combination treatment. Forty‐six tumours were positively enhanced by CO 2 ‐US and 40 of them were positive by angiography. These 46 tumours were proved to be viable tumours either by biopsy or by follow‐up studies. The positive predictive value was 100% for CO 2 ‐US and 87.8% in angiography. Twenty tumours were negative by CO 2 ‐US and these were also negative by angiography. Carbon dioxide‐enhanced ultrasonography is a more reliable method for detecting the viable portion of the treated HCC compared with conventional angiography.
