title: [Contrast agents in magnetic resonance imaging].
abstract: Changing different parameters involved in imaging procedures, paramagnetic substances provide contrast enhancement in MRI. Contrast agents presently studied in animals and clinical trials, are either salts or complexes of mineral ions either nitroxide stable free radicals. Their development should extend the possibilities of tissular characterization and functional or metabolic evaluation of the MRI.
