Gallbladder and bile duct contractile function tests

Gallbladder and biliary tract systolic function examination B-ultrasound examination of gallbladder and biliary tract systolic function, also help to improve the diagnosis of gallstones and cholecystitis. The subject's fasting B-ultrasound measures the length and length of the longitudinal section of the gallbladder and the width of the cross-section. Eat animal fried eggs for 2 60 min. The above three paths of the gallbladder after the meal were measured.

The above three paths of the gallbladder after the meal were measured. The shrinkage rate of the gallbladder%=(fasting three-path product-fat meal three-path product)/fasting three-way product×100%.
