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 .

Gallbladder diseases are diseases involving the gallbladder and is closely linked to biliary disease, with the most common cause being gallstones (cholelithiasis). [1] [2]The gallbladder is designed to aid in the digestion of fats by concentrating and storing the bile made in the liver and transferring it through the biliary tract to the digestive system through bile ducts that connect the ...
Failure of gallbladder visualisation during oral cholecystography when abnormal liver function returns to normal, or there is mild to moderate liver disease, maybe due to extrahepatic (outside the liver) causes. [4]
The CCK test may be administered in conjunction with an ultrasound test to visually monitor gall bladder contraction. While the test is usually administered in a supine position Dr. William Smedley of Wilkes Barre, Pennsylvania has detected previously missed gallbladder abnormalities by administering the test in an erect position.
There are at least four types of cholangiography: [citation needed] Percutaneous transhepatic cholangiography (PTC): Examination of liver and bile ducts by x-rays. This is accomplished by the insertion of a thin needle into the liver carrying a contrast medium to help to see blockage in liver and bile ducts.
The cholecystokinin B receptor also known as CCKBR or CCK 2 is a protein [5] that in humans is encoded by the CCKBR gene. [ 6 ] This gene encodes a G protein-coupled receptor for gastrin and cholecystokinin (CCK), [ 7 ] [ 8 ] [ 9 ] regulatory peptides of the brain and gastrointestinal tract.
Meanwhile, in concert with secretin's actions, the other main hormone simultaneously issued by the duodenum, cholecystokinin (CCK), stimulates the gallbladder to contract, delivering its stored bile. Prosecretin is a precursor to secretin, which is present in digestion. Secretin is stored in this unusable form, and is activated by gastric acid ...
