RECONSTITUTABLE MICROSPHERE COMPOSITIONS USEFUL AS ULTRASONIC CONTRAST AGENTS

摘要

Methods and suspensions are provided that are useful for preparing readily reconstitutable, dry compositions of micro- or nanospheres. The dry compositions find use in diagnostic applications such as ultrasonic imaging. The suspension includes as key ingredients one or both of t-butyl alcohol and/or an amorphous sugar (or mixture of amorphous sugars) in specified amounts that reduce aggregation of the particles comprising the suspension.
