Overview
An x-ray may be helpful in the diagnosis of gallstone disease. Findings on an x-ray suggestive of gallstones include cholesterol and pigment radio-opaque stones found in the gallbladder or biliary tree within the common bile duct or the 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 - 80%. Gallstones may be missed on CT because many stones are isodense with bile.[1][2]
Percutaneous transhepatic cholangiography
X-rays are 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.
