ABDOMINAL ULSTRASOUND IMAGING Abdominal ultrasound imaging is carried out by oral or rectal administration of an aqueous imaging composition containing micron size inorganic particles together with a sufficient amount of a solubilized hydrocolloid to maintain the particles in suspension. The walls of the stomach, duodenum and colon become coated with the particles and are thereby more clearly delineated by the ultrasonic imaging beam. At the same time, ultrasonic waves partially pass through the walls and delineate structures outside thereof. Wall delineation and wall transparency can thereby be simultaneously achieved.
