Abstract
A method of ultrasonic imaging for use in medical procedures is disclosed. The method comprises providing specifically defined microbubbles formed by sonicating a bicompatible liquid comprising a sonicated aqueous protein solution, preferably a 5% solution of human serum albumin, and denaturing the protein therein by heat or chemical methods; injecting the microbubbles into an animal or human to thereby alter the acoustic properties of an area to be imaged; and then ultrasonically scanning the area so as to obtain an ultrasound scanning image.
