PURPOSE: To demonstrate a self-derived, dynamic field map (∆B0) estimation and correction method for improved CEST measurements without additional scans, especially in the presence of subject motion. METHODS: Dynamic ∆B0 maps were derived directly from the CEST images acquired with rosette readout trajectories by segmenting the rosette k-space data. The rosette ∆B0 mapping accuracy was validated a
