The investigation is usually conducted after an ultrasonographic examination of the abdominal right upper quadrant for a patient presenting with abdominal pain.If the noninvasive ultrasound examination fails to demonstrate gallstones, or other obstruction to the gallbladder or biliary tree, in an attempt to establish a cause of right upper quadrant pain, a cholescintigraphic scan can be ...
Indeterminate biliary strictures and suspected bile duct tumors [3] Suspected injury to bile ducts either as a result of trauma or of iatrogenic origin; Sphincter of Oddi dysfunction; Chronic pancreatitis is currently a controversial indication due to widespread availability of safer diagnostic modalities including endoscopic ultrasound, CT ...
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.
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.
Pneumobilia is the presence of gas in the biliary system.It is typically detected by ultrasound or a radiographic imaging exam, such as CT, or MRI.It is a common finding in patients that have recently undergone biliary surgery or endoscopic biliary procedure.
Besides providing information regarding the biliary system, MRCP also provides information regarding surrounding solid organs and blood vessels, thus useful for planning the resection of pancreatic cancer and look for complications of primary sclerosing cholangitis such as liver cirrhosis and cholangiocarcinoma.

Courvoisier's sign occurs due to the gradual (chronic) nature of the obstruction caused by cancer (e.g. pancreatic, often located in pancreatic head, cholangiocarcinoma, etc.), which gradually causes biliary back-pressure and gradually distends the gallbladder over time, without causing acute damage, thus without causing pain.
The remaining 50% are due to non-biliary causes. This is because upper abdominal pain and gallstones are both common but are not always related. Non-biliary causes of PCS may be caused by a functional gastrointestinal disorder, such as functional dyspepsia.
