Figure 3: MRI acquisitions at of the phantom samples used for relaxivity calculation. Rows A and C show DOTAREM solutions ( and weighted MRI acquisitions, resp.) at increasing Gd3+ concentration listed below the figure, while rows B and D show D3 solutions at the same concentrations/conditions as for DOTAREM, except by 0 mM (pure water). There was only one 0 mM (no CA) phantom tube. The faint image corresponding to 0 mM is outlined with a dotted white line in the weighted acquisitions for better visualization.
