Hepatocellular carcinoma treated with radiofrequency ablation: Comparison of pulse inversion contrast-enhanced harmonic sonography, contrast-enhanced power Doppler sonography, and helical CT.

Hepatitis C virus infects millions of people worldwide. As the world’s population ages, the incidence of Hepatitis C related hepatocellular carcinoma will increase. Any help in dealing with this lethal disease is most welcome. The authors discuss both minimally invasive approach to therapy with radiofrequency ablation and the use of various radiological techniques to assess efficacy. The latter includes a relatively new use of contrast enhanced pulse harmonic imaging that shows great promise.
