USPIOs Quantification in Brain Mice 2D MR Images by Default Field Deconvolution

Delphine Charpigny¹, Jean-Christophe Brisset¹, Thomas Grenier¹, Marlene Wiart¹, Hugues Benoit-Cattin¹

We propose to assess the USPIOs concentration through the deconvolution of the default field induced by such nanoparticles. We present results obtained at 7T on MR images of brain mice after injection of USPIOs-labeled cells. The obtained results are promising as we estimate the iron concentration to 0.35 mM compared to a theoretical value of O.32 mM.
