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

Figure 5

Magnetic resonance image montage of the progression of contrast media diffusion through a dialysis cassette at 𝑡=0, 329, 407, and 1489 minutes after injection, starting from top-left row, ending at bottom right. At 24 hours, the Gd DTPA-BMA (left fixture) has leaked out, while the HWO1-147 (right fixture) is relatively well-retained inside its cassette.
