A normal gallbladder ultrasound is characterized by a pear-shaped organ with an anechoic (dark) lumen, a thin wall, and no intraluminal echogenic foci that cast posterior shadowing. There should be no sludge, no pericholecystic fluid, and the gallbladder should not be distended by stones or inflammation. The bile ducts—both the common bile duct and the intrahepatic ducts—should appear nondilated, with the common bile duct typically under about 6–7 mm in adults. No masses should be seen in the pancreas or surrounding tissues.

So, when the ultrasound findings show a normal gallbladder without stones, wall thickening, ductal dilation, or any mass, the result is best described as normal biliary/gallbladder. If stones were present, you’d expect echogenic foci with shadowing; if the ducts were dilated, that would suggest obstruction; a pancreatic mass would appear as a distinct lesion in the pancreas.
