Abstract:
Objective To assess the value of contrast-enhanced ultrasound(US)in differential diagnosis of hyperechoic hepatic lesions when compared to conventional US.Methods Eighty-four hyperechoic liver lesions in 66 patients were examined using both conventional and contrast-enhanced US techniques.Results Receiver operating characteristic analysis revealed a significant improvement in the discrimination of malignant versus benign hyperechoic hepatic lesions (area under the receiver operating characteristic curve,0.867±0.045 at conventional US,0.997±0.003 with contrast-enhanced US(P＜0.0001).For correct diagnoses types of hyperechoic liver lesions,contrast-enhanced US improved from 64.3% to 92.9%,comic)ared with conventional US (P＜0.001).Conclusions Contrast-enhanced US showed a significant improvement in characterization and differentiation of hyperechoic hepatic lesions when compared to conventional US.
