Research Progress of Magnetic Resonance Imaging Contrast Agents
Abstract Magnetic resonance imaging (MRI) is one of the most useful diagnostic techniques in clinical medicine and more than 30% of all MRI examinations are accompanied by administration of a contrast agent which has become a class of pharmaceuticals. The principles, characterization and classification and recent developments of MRI contrast agents are presented in this review. The primary focus of such research is to study the MRI contrast agents with organ-selectivity, high relaxivity and safety.
