Urgent real-time cholecystosonography in suspected acute cholecystitis.

Acute cholecystitis was suspected in 60 patients. Correct diagnoses were achieved by urgent real-time cholecystosonography in all the 38 patients that had acute cholecystitis. In about one-third of the other cases sonography revealed the pathological states responsible for the symptoms simulating those of acute cholecystitis. All of the examinations were technically satisfactory.
