It has been established that the topography of the spleen in cattle changes depending on the rumen filling and is corrected by a starvation diet, because the spleen is located in the left hypochondrium on the rumen. The animal should be fixed in a lateral position in the stall. Available puncture sites are the 10th, 11th, and 12th intercostal spaces. Ultrasound scanning is best to be performed paracostally, parallel to the caudal surface of the appropriate rib, slightly below the transverse processes of the thoracic vertebrae at the level of the horizontal line of the hook bone. The biopsy needle should be directed towards the opposite ulnar process (standard G 18 guillotine needle for biopsy of parenchymal organs, diameter 1.2 mm, with the length no less than 75 mm). The needle trajectory is visualized in the focus area of the scanner's ultrasonic sensor.
