The Presence of Fast-Exchanging Proton Species in Aqueous Solutions of paraCEST Agents Can Impact Rate Constants Measured for Slower Exchanging Species When Fitting CEST Spectra to the Bloch Equations
[Image: see text] LnDOTA-tetraamide complexes typically exist in solution as a mixture of square-antiprismatic (SAP) and twisted square-antiprismatic (TSAP) coordination isomers. In most cases, the SAP isomer, which is preferred for CEST imaging, predominates, and the presence of the minor TSAP isom...
