Most often, these stones are multiple, and 85% of them are radiolucent and cannot be seen on regular x-ray films.
Which type of gallstones are radiopaque?
Black pigment or mixed gallstones may contain sufficient calcium to appear radiopaque on plain films. The finding of air in the bile ducts on plain films may indicate the development of a choledochoenteric fistula or ascending cholangitis with gas-forming organisms.
Are brown gallstones radiolucent?
