Abstract
This study investigated whether contrast-enhanced sonography can accurately predict
the ablated area by radiofrequency ablation using virtual sonography by computed tomography
as a gold standard.
Thirty-one hepatocellular carcinoma nodules were treated by radiofrequency ablation
and then examined. The defect of contrast-enhanced sonography (puncture direction:
r=.868, P<.0001; perpendicular direction; r=.925, P<.0001) was closely correlated with the unenhanced area of virtual sonography.
Contrast-enhanced sonography can be used for early and accurate prediction of the
ablated area and is helpful for assessing local control of radiofrequency ablation.
