We elucidated the clinical use of contrast-enhanced ultrasonography (US) with Levovist^[○!R] in HCC hemodynamics in comparison with dynamic CT. The vascularity of 36 HCC nodules were compared with both contrast-enhanced US and CT. Agent detection imaging (ADI) with Secoia 512 (Aquson Co., USA) was used. The detection rate of feeding artery and/or tumor enhancement in the arterial phase was almost same in each modality. On the other hand, 83.3% of the nodules showed the same findings between tumor stain on CT and tumor enhancement on enhanced US at 2～5 minutes after injection of Levovist. This discrepancy between these modalities in parenchymal phase (2～5 min after injection) might be due to the difference between liquid contrast enhance of CT and microbubble by Levoist. Simplicity, short time and low incidence of adverse effect were the beneficial points on contrast-enhanced US with Levovist. We consider that this method is useful to examine the hemodynamics of HCC with the same ability as dynamic CT.We elucidated the clinical use of contrast-enhanced ultrasonography (US) with Levovist^[○!R] in HCC hemodynamics in comparison with dynamic CT.
