They address both classic indications in neurology and orthopedics and MR cholangiography, urography, and colongraphy. |
How reliable is intraoperative cholangiography as a method for detecting common bile duct stones? |
Percutaneous transhepatic cholangiography can also be performed to demonstrate the patency of the common bile duct. |
When necessary, colorful schematic illustrations and radiologic studies, including cholangiography, sonography, and computed tomography, have been added. |
Percutaneous transhepatic cholangiography is radiography of bile ducts via needle puncture. |
Intravenous cholangiography is rarely used now as opacification of the bile ducts is poor, particularly in jaundiced patients, and anaphylaxis remains a problem. |
