Ultrasonographic image of the left abdomen of horses with colic associated with enteritis and/or colitisusing 3.5 MHz transducer. The intestinal loops appear distended with fluid contents; the intestinal wall is slightly thickenedand corrugated. Increased intestinal motility of the intestinal loops was detected on the screen.
