Gallbladder wall thickening: a new sign of gallbladder disease visualized by gray scale cholecystosonography

The use of gray scale equipment in a prospective study of radiologically non-visualizing gallbladders, permitted detection of a new echographic aspect of gallbladder disease. Along with even, discrete bile thickening and the presence of sand-sized calculi, thickening of the gallbladder wall incholecystitis is another ultrasonographic sign of gallbladder disease that can be visualized successfully by gray scale ultrasound.
