We aimed to explore the difference of amide proton transfer-weighted (APTw) imaging combined with DKI between the chemotherapy group and non-chemotherapy group of rectal cancer. The result showed that the highest diagnostic efficacy(AUC: 0.986; sensitivity: 91.8%; specificity: 100%) was acquired using APT combined with DKI, rather than APT and DKI value respectively.
