Overview
An x-ray may be helpful in the diagnosis of gallstone disease. Findings on an x-ray suggestive of gallstones include radioopaque stones within the gallbladder or biliary tree including the common bile duct and cystic duct.
X Ray
Plain abdominal x-rays rarely detect gallstones since only 10% of gallstones contain enough calcium within them to be sufficiently radioopaque and be visible on a radiograph. The majority of stones are therefore, radiolucent. CT scan sensitivity for gallstones has been estimated to be 55 to 80 percent. Gallstones may be missed on CT because many stones are isodense with bile.[1][2]
Percutaneous transhepatic cholangiography
X-rays can be used to examine the liver and bile ducts. This is accomplished by the insertion of a thin needle through the skin and into the liver carrying a contrast medium to help to see blockages in liver and bile ducts.
