Abstract
A composition for ultrasonic imaging is described having a microbubble population of controlled fragility. The microbubbles comprise an outer shell and a hollow core. The ratio of shell thickness to microbubble diameter is substantially similar across the population of microbubbles. A method of using such composition for imaging a fluid filled cavity, vessel or tissue is described.
