Answer

Answer

The advantages of abdominal radiographs include their readily availability and low cost. However, abdominal radiographs have low sensitivity and specificity in evaluating biliary system pathology, but they can be helpful in excluding other abdominal pathology such as renal colic, bowel obstruction, perforation. Between 10% and 30% of stones have a ring of calcium and, therefore, are radiopaque. A porcelain gallbladder also may be observed on plain films.

Emphysematous cholecystitis, cholangitis, cholecystic-enteric fistula, or postendoscopic manipulation may show air in the biliary tree. Air in the gallbladder wall indicates emphysematous cholecystitis due to gas-forming organisms such as clostridial species and Escherichia coli.
