Endoscopic retrograde cholangiopancreatography (ERCP) is considered a gold standard test for diagnosing biliary obstruction. Magnetic resonance cholangiopancreatography (MRCP) and percutaneous transhepatic cholangiography (PTCA) are the most sensitive techniques to correctly determine the underlying cause and level of biliary obstruction in patients with acute cholangitis when ERCP fails.
