<b>Treatment of Hepatocellular Carcinoma with Percutaneous Radiofrequency Ablation:</b> Usefulness of Contrast Harmonic Sonography for Lesions Poorly Defined with B-Mode Sonography

Abstract

Contrast harmonic sonography helps in the placement of radiofrequency ablation electrodes in hypervascular hepatocellular carcinomas that cannot be adequately depicted by B-mode sonography.
