Our work aimed to explore the value of amide proton transfer-weighted (APTw) imaging in diagnosing primary and secondary malignant liver tumors. The result manifested that the novel imaging tool had a valuable utility in differentiating primary from secondary malignant liver tumors (AUC: 0.879; sensitivity: 76.9%; specificity: 100%).
