Accelerating Chemical Exchange Saturation TransferImaging using a Diffusion Model
Motivation: Chemical exchange saturation transfer (CEST) magnetic resonance (MR) imaging is slow, and rapid radial undersampling significantly compromises the image quality of CEST data. Goal(s): Our goal is to enhance the image performance of CEST reconstruction under higher radial undersampling. Approach: A diffusion model is introduced to obtain prior information from MRI data, and its performance is evaluated on CEST data under radial sampling. Results: The proposed method generated high-quality CEST source images in healthy human data, outperforming iGRASP. Impact: The proposed method has achieved rapid imaging of CEST data, providing high-quality CEST source images .
