Choledochal cyst - type I
Type I choledochal cysts appear as a fusiform or cystic dilatation of the extrahepatic biliary system (common bile duct +/- common hepatic duct).
Epidemiology
Although uncommon in Western countries (1:100,000 to 1:150,000), they are the most common type of biliary cyst. Their prevalence may be...

Hepatobiliary imaging in nuclear medicine
Hepatobiliary imaging in nuclear medicine can be accomplished with multiple different radiotracers to help evaluate the liver, gallbladder and the biliary ducts. The choice of tracer depends on the clinical question.
Common tracers include:
Tc-99m IDA (iminodiacetic acid) analogues: most commo...

Tc99m IDA (iminodiacetic acid) analogues
Tc99m IDA (iminodiacetic acid) analogues are hepatobiliary agents in nuclear medicine, used in cholescintigraphy.
These include:
Tc99m-DISIDA: diisopropyl IDA, also known as Hepatolite
Tc99m-Mebrofenin: trimethyl bromo IDA, Choletec TM
Tc99m-PIPIDA: paraisopropyl iminodiacetic acid

Cholescintigraphy
Cholescintigraphy is the use of radiotracers to assess the anatomy and function of the biliary system (and the liver indirectly). This is most commonly performed with Tc-99m-IDA analogues 1, and "hepatic IDA" imaging gave rise to the more common term "HIDA scan."
Indications
