HIDAskoðun

HIDAskoðun, commonly known as Hepatobiliary Iminodiacetic Acid (HIDA) scanning, is a nuclear medicine imaging test used primarily to evaluate the biliary system, which includes the liver, gallbladder, bile ducts, and pancreas. This diagnostic procedure helps identify issues such as bile duct obstructions, gallbladder inflammation (cholecystitis), or other biliary tract disorders.

During the procedure, a small amount of a radioactive tracer, typically HIDA (also called iminodiacetic acid), is injected into the patient’s vein. The tracer is absorbed by the liver cells and secreted into the bile ducts. A gamma camera then captures images of the tracer’s movement through the biliary system, allowing medical professionals to assess its function and detect any abnormalities.

HIDAskoðun is often recommended for patients experiencing symptoms such as persistent abdominal pain, jaundice, or elevated liver enzyme levels. It is particularly useful in diagnosing conditions like acute cholecystitis, where the gallbladder fails to empty properly, or biliary obstruction, where bile flow is blocked. The test is generally safe, with minimal risks, though some patients may experience mild discomfort from the injection or allergic reactions to the tracer.

The procedure typically takes about one to two hours, including preparation and imaging time. Patients are usually asked to fast beforehand to ensure accurate results. The images produced provide valuable insights for diagnosing and planning treatment for biliary system disorders, making HIDAskoðun an essential tool in medical diagnostics.
