In the current study, texture analysis of multiple high b-values DWI was demonstrated to be capable to identify primary hepatic cancer and hepatic metastases, which provided abundant quantitative information that may facilitate clinical management. The results showed that texture features based on b800 and b2000 DWI images was the optimal strategy to identify different types of hepatic malignant tumors (b800: sensitivity 92.0%, specificity 84.2%; b2000: sensitivity 84.0%, specificity 94.7%).
