On the Use of Molecular Weight Cutoff Cassettes to Measure Dynamic Relaxivity of Novel Gadolinium Contrast Agents: Example Using Hyaluronic Acid Polymer Complexes in Phosphate-Buffered Saline

<table>Hyaluronic acid repeat unit with amide bound diethylenediamine pentacetic acid. The Gd<sup>3+</sup> ion is complexed with the bound DTPA ligand to yield the imaging agent, which is then coupled to HA via standard carbodiimide coupling methods.</table>
