More Information
Summary:Microcapsules which can be used in medical imaging, consisting of a wall made of biodegradable polymeric material enclosing an aqueous solution of an active substance, wherein the aforementioned active substance is a complexing or chelating agent or a paramagnetic and/or radioactive agent present in the form of a complex or chelate, and wherein the aforementioned particles can range from 0.5 to 5 micrometres approximately in size; and their use. MICROCAPSULES UTILISABLES EN IMAGERIE MEDICALE, CONSTITUEES PAR UNE PAROI EN MATERIAU POLYMERIQUE BIODEGRADABLE ENVELOPPANT UNE SOLUTION AQUEUSE D'UNE SUBSTANCE ACTIVE, CARACTERISEES PAR LE FAIT QUE LADITE SUBSTANCE ACTIVE EST UN AGENT COMPLEXANT OU CHELATANT OU UN AGENT PARAMAGNETIQUE ETOU RADIOACTIF PRESENT SOUS LA FORME D'UN COMPLEXE OU CHELATE, ET QUE LESDITES PARTICULES ONT DES DIMENSIONS POUVANT ALLER DE 0,5 A 5 MICROMETRES ENVIRON; ET LEUR UTILISATION.
