Hida scan showed clogged bile duct, but my physician says she doesn't think it is biliary atresia. what does this mean?

Other cause of block: Hida scan is a nuclear medicine test to check on the flow of bile from liver, into gallbladder, and bile ducts. Safe test. Results can be: normal; no visualization of dye in the gallbladder (may mean blockage by stone, inflammation-cholecystitis, less likely tumor); slow movementvisualization-may reflect liver trouble, blockage, inflammation of bile ducts; seen elsewhere than bil sys/gi-leakage.

Sludge: Bile sludge can cause non visualization of ducts or absence of flow of bile into intestines. An open liver biopsy and cholangiogram can confirm and wash the sludge loose.

Obstruction: Biliary atresia is a disease of children. In adults, this can mean stones or tumor disease.
