title: Gelatin encapsulated nitrogen microbubbles as ultrasonic contrast agents.
abstract: Gelatin encapsulated nitrogen microbubbles were effective ultrasonic contrast agents in in vitro phantom and in vivo rabbit V2 carcinoma studies. Intra-arterial injection of 80-micrometer gelatin encapsulated nitrogen microbubbles appeared to improve tumor visualization by rim enhancement, which persisted for several minutes.
