Postoperative complications, such as bile leaks and fistulas.Congenital abnormalities in the bile ducts, such as biliary atresia.Gallbladder inflammation (cholecystitis).A HIDA scan is often used with X-ray and ultrasound.Ī HIDA scan might help in the diagnosis of several diseases and conditions, such as: It’s also used to look at the bile-excreting function of your liver and to track the flow of bile from your liver into your small intestine. Reasons for HIDA scanĪ HIDA scan is most often done to evaluate your gallbladder. In the presence of cystic duct obstruction the gallbladder does not fill with isotope. These situations include severe liver disease, patients on total parenteral nutrition, hyperbilirubinemia, inadequate fasting, and alcohol and opiate abuse. HIDA scans can be falsely positive when the gallbladder is not filling in the absence of cholecystitis. In a healthy person, HIDA will pass through the bile ducts and into the cystic duct to enter the gallbladder. If the HIDA enters the bile ducts but does not enter the small intestine, then an obstruction of the bile duct (usually due to stones or cancer) is suspected.In cholecystitis, HIDA will appear in the bile ducts, but it will not enter the cystic duct or the gallbladder - a finding that indicates obstruction.Such a scenario is consistent with acute cholecystitis, which often requires surgical removal of the gallbladder.Usually, HIDA scans are ordered for patients who are suspected of having an obstruction in the biliary tract, most commonly those who are thought to have a stone blocking the cystic duct leading out of the gallbladder.The HIDA scan should be done when ultrasound is not diagnostic and when there is a clinical diagnosis of acute cholecystitis.After the gallbladder scan, the person may be prepared for surgery, if needed. HIDA scan is combined with other imaging (such as CT or ultrasound). For this reason, some people may need urgent treatment based on the test results. Most of the time, HIDA scan is done only if a person has sudden pain that may be from gallbladder disease or gallstones. A nuclear medicine scanner (gamma camera) tracks the flow of the tracer from your liver into your gallbladder and small intestine and creates computer images. The tracer then travels with the bile into your gallbladder and through your bile ducts to your small intestine. The tracer travels through your bloodstream to your liver, where the bile-producing cells (hepatocytes) take it up. During a HIDA scan, a radioactive tracer is injected into a vein in your arm. Currently, HIDA scan is most commonly performed with Tc99m-iminodiacetic acid analogues. HIDA scan is used to diagnose problems of the liver, gallbladder and bile ducts. So here’s some questions, any feedback welcomed.HIDA scan is also known as hepatobiliary hydroxy iminodiacetic acid (HIDA) scan, cholescintigraphy or hepatobiliary scan or hepatobiliary scintigraphy, is an imaging procedure that uses radiotracers to assess the anatomy and function of the biliary system (and the liver indirectly).

Louisiana is an outlier with proportionately greater number of TB cases than other states. A correlation could be drawn in those states having large cities as compared to other mid-western states.ĭistribution is fairly consistent with measles being the most diagnosed ailment.
