Techniques that produce images of the liver, gallbladder, bile ducts, and blood vessels supplying the liver, to aid the detection of disease. Ultrasound scanning, CT scanning, and MRI are commonly used. Radionuclide scanning may reveal cysts and tumours and show bile excretion. X–ray techniques include cholangiography, cholecystography, and ERCP (endoscopic retrograde cholangiopancreatography). In these procedures, a contrast medium, which is opaque to X-rays, is introduced to show abnormalities in the biliary system. Angiography reveals the blood vessels in the liver.
