“…In this study, we have synthesized hPRM1 and determined how its CEST MRI contrast varies as a function of pH, phosphorylation state, and upon noncovalent interaction with nucleic acids and heparin (as antagonist). …”

“…Its counterpart MUC1 is a large polymer rich in glycans containing multiple exchangeable OH protons, which is readily detectable by chemical exchange saturation transfer (CEST) MRI. We show here that deglycosylation of MUC1 results in >75% reduction in CEST signal. …”

“…METHODS: Herein, we propose a K-means clustering method for accelerated Lorentzian estimation (KALE) in CEST quantification. Briefly, voxels in CEST images are clustered into K groups according to their Z-spectra characteristics. …”

“…Both Olsa-RVRR and Olsa-NPs could be readily detected with chemical exchange saturation transfer magnetic resonance imaging (CEST MRI) by virtue of exchangeable olsalazine hydroxyl protons. …”

“…In this study, this approach employed a simplified Lorentzian model containing only two pools of symmetric water and asymmetric solutes, to describe the Z-spectral shape with wide and ‘invisible’ CEST peaks. The B(0) correction was then performed on the basis of the fitted two-pool Lorentzian lines, instead of using conventional model-free interpolation. …”
