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.

摘要

本研究旨在探讨对比增强超声是否可以通过计算机断层扫描虚拟超声作为金标准来准确预测射频消融的消融面积。31 个肝细胞癌结节接受射频消融治疗后进行检查。对比增强超声的缺损（穿刺方向：r=.868，P<.0001；垂直方向；r=.925，P<.0001）与虚拟超声的未增强区域密切相关。对比增强超声可用于早期和准确预测消融面积，有助于评估射频消融的局部控制。
