(A, B) \({T}_{1}\) maps (pixel units are seconds) of the AGuIX concentration phantom consisting of sealed vials of varying AGuIX-saline solutions submersed in water. (C) Measured \({T}_{1}\) (average \({T}_{1}\) within each vial containing an AGuIX-saline solution) plotted against known concentration (the concentration each vial was designed to contain). (D) Relaxivity plot; inverse change in \({T}_{1}\) plotted against known concentration, where the change in \({T}_{1}\) is calculated using the saline \({T}_{1}\) measurement as baseline and the AGuIX-saline solution \({T}_{1}\) measurements as the change resulting from nanoparticles.
