Answer

Abdominal ultrasonography should be performed to exclude biliary obstruction and to evaluate the liver parenchyma for possible cirrhosis, tumor, steatosis, or congestion. [13]

Ultrasonography is safe, noninvasive, and portable. This image modality provides good visualization of the gallbladder, bile ducts, and cystic lesions and can detect parenchymal liver disease, such as cirrhosis or infiltration, and signs of portal hypertension.

However, ultrasonography also has a limited resolution, and it may not detect common bile duct stones because of the presence of bowel gas.
