<prompt> Answer this question truthfullyWhat other imaging findings are associated with Biliary Atresia?  <response>: <reason> Cases of biliary atresia typically demonstrate relatively good hepatic uptake with no evidence of excretion into the bowel at 24 hours. Pretreatment with phenobarbital 5 mgkgday for 5 days is done to stimulate hepatic enzymes in order to increase biliary secretion. This is helpful to minimize the possibility of a false-positive study due to pre-existing poor excretion. Radiotracers used are Tc-99m diosgenin DISIDA and mebrofenin BRIDA due to high hepatic extraction and short transit time.Further testing include radioactive scans of the liver and a liver biopsy.
