Abstract

The present invention provides a method for performing whole-body, WB, amide proton transfer weighted/chemical exchange saturation transfer, APTw/CEST, magnetic resonance imaging, MRI, the method comprising the following method steps: S1) B0 magnetic field shimming for B0 magnetic field homogenization and B1 radiofrequency field shimming for B1 radiofrequency field homogenization at multiple body positions and/or multiple imaging stations, S2) measuring data including coil sensitivity, resonance frequency, B0 magnetic field maps, and B1 radiofrequency field maps at multiple body positions and/or multiple imaging stations, S3) adapting a sequence operation protocol for the APTw/CEST locally at multiple body positions and/or multiple imaging stations, based at least in part on the measured data, S4) acquiring APTw/CEST MRI data at multiple body positions and/or multiple imaging stations on the basis of the adapted sequence operation protocol, S5) processing the acquired APTw/CEST MRI data for visualization, and S6) visualizing the processed APTw/CEST MRI data. In this way, a method is provided for performing whole-body APTw/CEST MRI that enables reliable, time-efficient, and spatially consistent imaging across multiple body regions.
