Biliary examination – abdominal ultrasound, abdominal CT or MRI performed on an empty stomach can help in examining the gallbladder and the bile ducts.
In magnetic resonance cholangiography, a substance excreted into the bile is administered, and then the bile-flow is examined with an MRI scanner.
An examination with a fibre-optic instrument, endoscopic retrograde cholangiopancreatography (ERCP), is suitable not only for examining the bile-ducts and the pancreas duct, but also for carrying out therapeutic procedures.
It can be used to remove stones lodged in the bile-ducts and to widen narrowings that obstruct the bile– and pancreas -flow.
With isotope methods, disorders of bile-excretion can be examined.
