The current amide proton transfer weighted (APTw) imaging cannot control the effect of respiratory motion artifacts effectively during image acquisition. Respiratory motion artifacts are a major factor affecting the quality of APTw imaging of the liver [1].In this study, according to the characteristics of APTw imaging acquisition, the healthy adult volunteers were divided into free-breathing (FB) group and intermittent breath-holding (IBH) group. The the right renal axial plane APTw imaging acquisition with the same parameters was performed. The analysis results showed that the success rate and repeatability of APTw imaging in the IBH group were better than FB group.
