Liver cancer and liver metastases are the most common liver malignancies. The accurate diagnosis of hepatocellular carcinoma (HCC) and hepatic metastasis (HM) is of great significance to the choice of treatment options. We aimed to explore the value of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) combined with T1 and T2 mapping to distinguish HCC from HM. Results showed that DCE combined with T1 and T2 mapping had the highest efficacy (AUC: 0.936; sensitivity: 81.8%; specificity: 100%).
