Hepatobiliary scan

Hepatobiliary scan is also known as HIDA scan or Cholescintigraphy and Hepatobiliary scintigraphy. This scan is an imaging procedure which is used to check liver, gallbladder and bile ducts. A tracer (radioactive) is injected in the vein of arm which travels via blood to liver and is taken up by bile-producing cells. With the bile, the tracer reaches the gallbladder and via bile ducts, it reaches to small intestine. The flow of tracer is tracked by gamma camera i.e. nuclear medicine scanner from liver to gallbladder and small intestine. Based on this images are created and stored in the computer.
