Ultrasonography is more helpful.  Biliary tract dilation can be seen in all cases.  Common bile duct is normally dilated and the [[Gall Bladder - Anatomy & Physiology|gall bladder]] may also be dilated with "sludge".  Main differential is extrahepatic biliary obstruction.

Liver biopsy is important to rule out Feline Infectious Peritonitis.  It is vital to obtain a haemostasis profile prior to biopsy due to risk of prolonged coagulation with liver disease.  It is unnecessary to obtain a bile sample unless the presentation is acute, in which case [[Neutrophilic Cholangitis]] needs to be ruled out.
