Saturation transfer effects were investigated in fixed tissue at 3T and 9.4T and a range of saturation powers. Z-spectra on magnitude as well as phase data were studied with high spatial and spectral resolution, also due to the excellent performance of a PCA-based denoising algorithm. The preliminary findings do not support the presence of an APT effect in fixed tissue; however, saturation transfer effects could be enhanced in pathological tissue, similar to in vivo findings in e.g. tumour or stroke. This study opens the way to a systematic investigation of saturation transfer effects in healthy and pathological fixed tissue.
