C., where x is the vapor pressure of the second gas at 37.degree. C., and wherein the vapor pressure of each of the first and second gases is greater than about 75 mm Hg at 37.degree. C.; also disclosed are methods for preparing microbubble compositions, including compositions that rapidly shrink from a first average diameter to a second average diameter less than about 75% of the first average diameter and are stabilized at the second average diameter; kits for preparing microbubbles; and methods for using such microbubbles as ultrasound contrast agents.
