Hepatocellular Carcinoma Treated with Percutaneous Radio-frequency Ablation: Usefulness of Power Doppler US with a Microbubble Contrast Agent in Evaluating Therapeutic Response—Preliminary Results

Abstract

The results of power Doppler US with a microbubble contrast agent in HCCs treated with RF ablation correlated well with those of contrast-enhanced CT. Preliminary data suggest that contrast-enhanced power Doppler US can be a promising noninvasive technique for assessing therapeutic response.
