Ultrasound

• Diagnostic evaluation of cholangitis should proceed first with ultrasound which has a overall sensitivity of 55-85%.
• It helps in visualizing stones and amount of common bile duct dilatation.
• Small stones in the common bile duct may be missed.
• The CBD may not be enlarged in cases of acute obstruction to CBD or if the stones has passed.
• The ducts may be totally normal in Primary Sclerosing Cholangitis.
