Abstract

Des cathéters chirurgicaux (1) sont constitués de matériaux qui sont non magnétiques et opaques ou translucides lors d'un examen par résonance magnétique nucléaire, et ont de préférence une structure segmentée, des segments de matière extrêmement opaque (5) alternant avec des segments de matière moins opaque (6) afin de faciliter l'observation du cathéter par reconstitution de l'image RMN.
