The aim of this study was to understand whether amide proton transfer (APT) contrast on brain tumor patient will be impacted by applying three different imaging sequences, spin-echo EPI, single-shot FSE, and a recent developed 3D FSE spiral. Although our finding on APT contrast appears to be similar among various sequences, careful consideration may be required when choosing the appropriate CEST readout sequences for your own applications.
