The present invention relates to a method of contrast enhanced ultrasonic diagnostic imaging comprising administering to a subject a contrast enhancing amount of spherical particles comprising a matrix enclosing a gaseous contrast agent which reflects sound waves, said matrix being a biocompatible, biodegradable, non-immunogenic non-polyamino acid synthetic polymer; and generating an ultrasonic image of said subject. The polymer may be selected from the group consisting of carbohydrates, carbohydrate derivatives and non-polyamino acid synthetic polymers.
