Cholescintigraphy or hepatobiliary scintigraphy is scintigraphy of the hepatobiliary tract, including the gallbladder and bile ducts.The image produced by this type of medical imaging, called a cholescintigram, is also known by other names depending on which radiotracer is used, such as HIDA scan, PIPIDA scan, DISIDA scan, or BrIDA scan.

Often diagnosed by HIDA scan, a bile leak from an accessory bile duct post-op can be treated with a temporary biliary stent [citation needed] to redirect the bile from the liver into the intestine and allow the accessory duct to spontaneously seal itself or using a drainage guided by radiology.

All of the hepatobiliary visualization agents previous to mebrofenin have the same structural composition with changes only of the substituants on the phenyl ring of the lidocaine analogue molecules. Mebrofenin's fast hepatic excretion (t ½ =17 minutes) and high hepatic uptake (98.1%) can be attributed to the 3-bromo-2,4,6-trimethylphenyl moiety.
However, clear fluid and routine medication is allowed before the scan. [1] Negative oral contrast such as pineapple juice, [ 1 ] date syrup, ferumoxsil, Açaí juice and water are useful in decreasing T2 signal intensity, thus minimising signals from stomach and duodenum from interfering with signals from the biliary system.
Percutaneous transhepatic cholangiography, percutaneous hepatic cholangiogram (PTHC) is a radiological technique used to visualize the anatomy of the biliary tract. [1] A contrast medium is injected into a bile duct in the liver, after which X-rays are taken.
Type II included patients with biliary-type abdominal pain associated with at least one of the following: altered liver enzymes on blood testing, dilated biliary ducts on imaging tests, and delayed bile clearance on HIDA scan. Biliary-type pain in the absence of any sign of biliary or pancreatic alteration was the so-called Type III biliary SOD.
Several technetium-99m complexes are used in cholescintigraphy scans (also known as hepatobiliary iminodiacetic acid scans) to evaluate the health and function of the gallbladder. [ 3 ] [ 4 ] Iminodiacetic acid is an important intermediate in one of the two main industrial processes used to manufacture the herbicide glyphosate .
