What is the scanning of hepatobiliary inminodiakutiic acid (HIDA)?


to HEPATOBILIOUS INMINOODY ACID (HIDA) scanning, which sometimes is also called Cholerentigraphy or hepatobiliary scintigrafy , this is the nuclear display test type,What are done to see the gallstones, gallbladder and liver.This test is performed by transitator injection, which contains a small amount of radioactive material in the blood, and then take pictures of the abdomen to visualize how the tracer moves through the body.The test gives an image of how the gallbladder and liver work and can take about an hour to be completed.

Purpose of the test

Scanning HIDA can be used to diagnose problems with a gallbladder,Since the liver highlights the bile and the stream of bile, since it leaves the liver and enters the small intestine . X-rays and ultrasound in the abdomen can also be done with Hida.Some of the conditions that can be diagnosed or are estimated using this test,Include:

  • Biliary atresia or other congenital values of the bile duct
  • Leaks or complications in the Bileary System (for example,Fistula)
  • Bubble of inflammation (cholecystitis)
  • Locking duct
  • Post Liver transplant Evaluation

Risks and contraindications

Hida -This is a test of nuclear medicine, and this type of test is generally not carried out in pregnant women. Therefore, if there is the possibility of pregnancy, women should allow their professionals or radiological personnel to know before having a test.Women should also allow their HealthCard provider to know if it is breastfeeding, since it can also affect the solution on this test

Risks of scanning more associated with tracers or medications,that are entered to complete the test.The Hida scan risks are low, but may include: / P>

  • Allergic reactions to Substances, used during the test (which rarely)
  • Bruise, Eruption or swelling,where the Inzhektorin plotter is in a small effect of the radiation

before The test

Practitioners or radiology employees will give instructions on how to prepare for the test.It is important to say that the health care provider about any current medication or additives for instructions when or how to take them on the day of the test.In some cases, the medication required for the test may need to take home before reaching the center. of radiology.

There may be a sensation of cold or a sense of pressure during the injection.In some cases, other drugs can also be introduced, including Kinevak (Sincalida) or Colestokinin (CCK), which activate the gallbladder and morphine , which can help direct the gallbladder tracking.Morphine is a painful medicine, and can cause drowsiness.

is similar to radiography, it is important to stay even during this test so you can take clear images.The imaging techniques will move the gamma camera on the abdominal cavity to make the images of the trageda, as it moves through the body.


The display device will instruct any restriction until the end of the day, but after the end of the test, most of the People will be able to have food and go through the day.The tracer will go through the body and is excreted from the body into a chair or urine.

  • Trazer did not enter the gallbladder, which can mean that the gallbladder is inflamed (which is called acutecholecystitis ).
  • The crawl left the bubble to the drop in the lowest amounts than expected, which may mean that the gallbladder is chronically inflamed, the condition of causing cholecystitis.
  • Trazer is out of the biliary system, which can mean that leak in the bile duct system or the drilling in the Terd Bubble.

MEDS information word received
