摘要
A system and method is provided that includes acquiring chemical exchange saturation transfer (CEST) data with the MRI system and generating an acquired Z-spectrum (Z) from the CEST data. The system and method also includes computing an estimated direct water saturation (Z′) based using at least one of relaxation measurements derived from the CEST data or imaging parameters used to acquire the CEST data with the MRI system, computing a direct saturation corrected Z-spectrum (ΔZ) using the acquired Z-spectrum (Z) and the estimated direct water saturation (Z′), and generating a CEST image of the subject using the direct saturation corrected Z-spectrum (ΔZ).
