Abstract

[automatically translated] Purpose: to evaluate the role of contrast-enhanced ultrasound (CEUS) in the characterization of focal liver lesions (FLLs) for surgical patients selection. Materials and Methods: 135 consecutive patients (71 women, 64 men) with 165 FLLs (mean size 3.1 cm) - 89 benign (10 simple cysts, 26 hemangiomas, 29 focal nodular hyperplasia (FNH), 2 hepatocellular adenomas, 11 focal fatty sparing, focal fatty areas 3, 5 regenerative nodules, 2 hydatid cysts, 1 abscess) and 76 malignant - 47 metastases, 26 hepatocellular carcinomas and 3 peripheral cholangiocarcinomas - underwent CEUS after the administration of SonoVue. Two reader reviewed in consensus baseline US and CEUS scans Obtained 25-30 s (arterial phase), 55-80 s (portal-venous phase), and 235-260 s (late phase) after the beginning of SonoVue injection rispettivamente. The reader classified each lesion as malignant or benign by means of defined diagnostic criteria. Sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy were Calculated. Results: CEUS has correctly caratterizzata 156/165 (94.5%) FLLs, 85 benign and 71 malignant. 5/165 (3%) FLLs, 3 hemangiomas and HCCs 2, Remained undetermined after CEUS and 4/165 (2.4%) FLLs, 3 HCCs and 1 abscess were misdiagnosed. Showed CEUS sensitivity, specificity, and diagnostic accuracy values of 93.4%, 95.5% and 94.7% rispettivamente. positive predictive value and negative predictive values were 94.7% and 94.4%.
