The size of the liver, as well as the situation and diameter of vessels in cattle were determined by use of ultrasonography. Ultrasonographic examinations of the liver were performed on 10 cows 10 times within 2 weeks, using a 3.5-MHz linear transducer on the right side in the 12th, 11th, and 10th intercostal spaces. Dorsal and ventral margin of the liver as well as localization and diameter of the caudal vena cava and the portal vein were determined in each intercostal space. Furthermore, the angle of the liver in the ventral area between the visceral surface and the diaphragmatic surface, the dorsal margin, and the circumference of the gall bladder were determined. The ultrasonographic values of liver size and localization in healthy cows can be used as reference values for the diagnosis of changes in liver size attributable to illness.
通过超声检查确定牛肝脏的大小以及血管的位置和直径。在2周内对10头奶牛进行10次肝脏超声检查，使用3.5兆赫的线性换能器在右侧第12、11和第10肋间间隙进行检查。在每个肋间间隙确定肝脏的背侧和腹侧边缘以及尾腔静脉和门静脉的位置和直径。此外，还确定了肝脏在内脏表面和膈面之间腹侧区域的角度、背侧边缘以及胆囊的周长。健康奶牛肝脏大小和位置的超声检查值可作为诊断因病导致肝脏大小变化的参考值。
