Hepatic disease in cats is often treatable and has a favorable prognosis with early diagnosis. This study
aimed to assess the liver status by using different diagnostic techniques including ultrasound, X-ray and
CT and cross section anatomy. Twenty- nine mongrel cats of both sexes with age range (1-5 years) and
weight range (1.5 –5kg) were used in this study. Cats were randomly divided into four groups. The 1^st
group had sixteen cats used for normal ultrasound study. The 2^nd group has five cats used for
cholecystography study by using urographin (R).The 3^rd group had three cats used for CT examination
and cross sections anatomy .The 4^th group had five cats subjected to experimental ligation of common
bile duct and Specimens were subjected to standardized processing and histopathological examination
for yielding definitive diagnosis of hepatic affections. The liver of cats appeared as 6 lobes located into
intrathoracic portion of the abdominal cavity.The hepatobiliary sonography was able to identify the
normal structure of the biliary system, evaluate of hepatobiliary affections, clarify the character of
hepatic damage and dysfunction and determine the possible primary causes of secondary hepatobiliary
diseases. The CT images from this study are intended as a reference for clinical CT imaging studies of
the liver of the cat and for interpreting lesions of the liver and associated structures. The serum
biochemical database comprises of ALT, AST and bilirubin was significant increase in obstruction of
common bile duct.
