    Medical imaging techniques such as magnetic resonance imaging (MRI) or ultrasonography are now well rooted into clinical practice. Nevertheless, to further improve the diagnostic of specific pathologies, contrast agents are needed. Materials used to formulate these agents should be carefully selected to interact with the physical stimulus in a way that the collected signal is as intense as possible, according to the imaging technique used. In addition, materials these agents are made of should exhibit no toxicity or the lowest toxicity compared to their medical benefits. We present here the state of the art for contrast agents used in MRI and ultrasonography. © 2017 médecine/sciences – Inserm.
