About
To explore an effective noninvasive method for differential diagnosis of liver tumors.
Full description
A retrospective study was performed to assess the performance of certain ultrasound-based parameters, in distinguishing benign from malignant with liver biopsy as the gold standard. Demographic data, clinical information and serological data were obtained from participants who were retrospectively enrolled. Receiver operating characteristic (ROC) curve analysis was conducted, including calculation of the optimal area under the ROC curve (AUC), to assess the performance of these measures in distinguishing between benign and malignant in patients with or without chronic liver disease.
