Amide proton transfer (APT) imaging employs the exchange between protons of free tissue water and the amide groups (-NH) of endogenous mobile proteins and peptides, imaged by a chemical exchange saturation transfer technique. APT imaging is expected to be a non-invasive method to measure proteins and peptides level in active tumors. In this study, we demonstrated the ability of APT imaging for prediction of histopathological grades of diffuse gliomas in a large patient population with histopathological evaluations.
