Gaseous ultrasound contrast media and method for selecting gases for use as ultrasound contrast media

摘要: Disclosed herein are agents for enhancing the contrast in an ultrasound image. These extremely small bubbles, or "microbubbles," comprised of specially selected gases. The microbubbles described exhibit long life spans solution and may be produced at a size enough to traverse lungs, thus enabling improved imaging cardiovascular system other vital organs. Also disclosed is method selecting gases from which produced. based on calculations using inherent physical properties describes means associate gas with time dissolution gas.
