The objective of the studies which included the comparison of the clinical, radiological and ultrasonographic examinations was the estimation of the mutual correlation between the changes in the ultrasound image of the liver and in other organs. The examinations were performed on 6 dogs and 5 cats of different breed and sex, aged from 1 to 13 years. The ultrasonic examinations were done with the ultrasound apparatus by Bruel and Kjaer type 1849 and Concept 2000 by Dynamic Imaging. In two cats there was an intensified reflection of the ultrasound beam from the liver parenchyma. In one of them the gross examination revealed panleukopenia and liver dystrophy. The reduction of echogenicity of liver parenchyma was observed in two cases. A significant enlargement of the gall bladder size and changes in the kidney parenchyma in the form of focal echoless areas were noted in one case. Hydronephrosis and uremia were additionally diagnosed in the other animal. Fatty generation of the liver was diagnosed in 3 animals with signs of significant overweight. In 4 patients with the ultrasound signs of the liver cirrhosis the clinical and x-ray examinations also revealed circulatory insufficiency (1 case), urinary system disorders (2 cases) and ascites (1 case). The suspicions of hepatitis, dystrophy, fatty degeneration and liver cirrhosis indicate the need for the ultrasonographic examination of the liver.
