How is the Test Performed?
The test is performed in a radiology department by a radiologist. You will be asked to lie on your back on the X-ray table. The upper right side of the abdomen is cleansed and a local anesthetic is given. A long, thin, flexible needle is then inserted through the skin into the liver.
With guidance from the fluoroscope (an X-ray machine that projects images onto a TV screen), the bile duct is located and the contrast medium injected. The contrast medium then flows through the ducts and can be seen on the fluoroscopic monitor.
