Abstract

Kontrastmidler bestående av gass-fylte eller gass-dannende polymere mikropartikler og/eller mikro-ballonger, der polymeren er en biodegraderbar polymer med enheter av formel (H) (D) (der R1 og R2 hver er hydrogen eller en karbon-bundet monovalent gruppe eller sammen danner en karbon-bundet divalent gruppe, og m og n, som kan være like eller forskjellige, er null eller 1) kan brukes i diagnostiske anvendelser som ultralyd eller MR avbildning.
