[The diagnosis of cholecystitis by ultrasonic densitometry].

Ultrasound densitometry was used to determine echo density of the wall and contents of the gallbladder in normal persons and in patients suffering from cholelithiasis and chronic calculus-free cholecystitis. In patients with cholelithiasis, the gallbladder was later removed, followed by histological examination of its wall. The ultrasound and histological data were studied and compared.
