What is disofenin?

Disofenin is: A compound that is actively cleared by the liver through the bile duct system. When 'labeled' with tc99m, a radioactive substance it can be visualized with a gamma camera. It's used for biliary imaging. There are other radiopharmaceuticals that behave similarly. It has no significant effect on the body.

Tracer...: Disofenin is a tracer used for a hida scan. Mebrofenin is another tracer which can be used for hida scan. The extraction ratios of the two tracers differ.

Agent for imaging gb: Disofenin is molecule attached to isotope Tc99m for gall bladder testing. This involves tricking liver to pick up isotope from blood stream and handle it like bilirubin excreting it in bile ducts, gall bladder, and eventually bowel.
