Abstract:
High intensity focused ultrasound(HIFU) is a technique that ultrasound energy is focused on tumor target to function the treatment through the biological effects including heating effect, cavitation effect and mechanical effect of body to caused cell coagulation necrosis in vivo. Ultrasound contrast agent is one of the most important applicational agent for the treatment of hepatocellular carcinoma(HCC). We discussed in this paper the application of ultrasound contrast agent in the diagnose and focusing of target before the treatment and the assesement of treatment of HCC. Considering the enhancement of cavitation effect, better acoustic environment that enhance biological efficacy of HIFU during the treatment of HCC, ultrasound contrast agent is drawing more attention as an HIFU enhancement agent.
