Abstract(s) :

(Anglais) Superparamagnetic iron oxide nanoparticles (SPM particles) are biocompatible MRI contrast agent used to track tumors or infections. They generate negative contrast on conventional MRI sequence [1]. Unfortunately, negative this contrast can be caused by other sources, which make difficult the SPM particles detection in a MR image (Fig. 1). To overcome this problem, new MRI sequences able to produce positive contrast near SPM particles are actually develloped. The ON-Resonance Saturation (ONRS) sequence [2] is studied in this work.
