Abstract

L'invention concerne un milieu de contraste, capable de bien se déposer sur la partie inférieure du tube digestif, après une administration par voie orale. Le milieu comprend une quantité suffisante d'agent de contraste pour pouvoir effectuer les diagnostics requis, en combinaison avec un modificateur de viscosité et un modificateur osmotique, ces deux modificateurs étant présents tous deux en une proportion pondérale par rapport audit agent d'au moins 1:20.
