What imaging result indicates a successful HIDA scan?

A successful HIDA (Hepatobiliary Iminodiacetic Acid) scan is characterized by clear visualization of the biliary tree, which includes the liver, gallbladder, and small intestine. This imaging technique evaluates the function of the liver and the patency of the biliary system.

When the radiotracer used in the scan is injected, it should be taken up by the liver and excreted into the bile, allowing for the visualization of the gallbladder and the biliary tree. A clear visualization of the biliary tree indicates that the bile is flowing properly from the liver through the gallbladder and into the duodenum, demonstrating that both the liver and the gallbladder are functioning correctly.

Other situations, such as no visualization of the gallbladder or retention of the agent in the liver only, would typically indicate potential problems, such as acute cholecystitis or obstruction in the biliary tree. A partially filled gallbladder suggests that there may be an issue with gallbladder function but does not provide the clear affirmation of biliary tree patency that is indicative of a successful scan. Thus, the clear visualization of the biliary tree is the marker of a successful HIDA scan
