Quoc L. Vuong, Jean-François Berret, Jérôme Fresnais, Yves Gossuin and Olivier Sandre A Universal Scaling Law to Predict the Efficiency of Magnetic Nanoparticles as MRI T2-Contrast Agents Advanced Healthcare Materials 1
This study evidences size, magnetization and magnetic volume fraction as the only control parameters of MRI T2 contrast agents. Experimental relaxation and magnetometry data on magnetic particles are used to construct a master curve, allowing the prediction of the efficiency of any nanoparticles or clusters. A calculation of the optimal sizes for T2 contrast agents of different natures is also performed.
