摘要
Abstract
Objective To investigate the application value of contrast-enhanced ultrasound(CEUS) time-intensity curve in the radiofrequency ablation treatment of hepatocellular carcinoma.Methods Seventy-six patients with hepatocellular carcinoma (118 tumor lesions) conducted the ultrasound-guided radiofrequency ablation therapy.The acoustic quantitative analysis software was employed to dynamically analyze the residual ablation lesions,which were compared with the examination results of synchronous enhanced MRI,with the pathology as the gold standard,the benign and malignant tumor residual ablation lesions were performed the statistically comparative analysis.Results The accuracy of CEUS effect after liver radiofrequency ablation therapy was 82.2 ％,which of enhanced MRI was 83.9 ％;the difference between CEUS and enhanced MRI had no statistical significance(P＞ 0.05),their examination results had higher consistency;the benign residual ablation lesions after radiofrequency ablation had blood perfusion characteristics different from malignant residual lesions,the time-intensity curve showed that IMAX benign residual lesions were smaller than malignant residual lesions(P＜0.01).The benign residual lesions of RT and TTP were longer than the malignant residual lesions(P＜0.01);diagnosing benign and malignant had no statistical difference between CEUS and enhanced MRI (P＞0.05).Conclusion CEUS combined with the time-intensity curve can dynamically,intuitively and quantitatively reflect the blood perfusion differences among inactivated focus,benign and malignant residual lesions,and the surrounding liver parenchyma.关键词
