Exploration of right-sided displacement in the true stomach of imported cows using B-ultrasound
After the cow's true stomach undergoes a right displacement, characteristic ultrasound images of the true stomach can be detected at non normal surface projection positions, and the corresponding positions of various internal organs have changed. Imported cows can be used for ultrasound exploration.
When performing B-ultrasound exploration of imported cattle near the dorsal side of the 8th and 9th ribs of the diseased cattle, characteristic liver features of the imported cattle can be detected using B-ultrasound images. Below, a weak echo of the true stomach can be detected, which is the junction between the true stomach and the liver. At the position near the abdomen between the 8th and 9th ribs of the diseased cattle, imported cattle detected a mixed echo true stomach ultrasound image and a mixed flap stomach ultrasound image with flap stomach leaf structure using ultrasound. This is the boundary between the true stomach and the flap stomach.
Exploration of the bottom of the 11 ribs of the diseased cow revealed densely distributed striped strong echo structures in the weak echo area below the abdominal wall, mixed with heterogeneous medium intensity echoes below. This is a typical imported bovine B-ultrasound image of the flap stomach.
In the middle of the 10th to 12th intercostal space of the right abdominal wall of the diseased cow or slightly close to the dorsal position, a worm like strong echogenic fold structure can be detected by B-ultrasound. These folds are closely attached to the abdominal wall presenting strong echogenicity, and the distance between each fold is relatively uniform. This is the true gastric fold, and the weak echogenicity with uniform texture between folds and below is the echo of the true gastric contents.
The position of the lower edge of the 13th rib arch in the diseased cow was explored, and a characteristic imported cow was observed using B-ultrasound imaging. A wavy and strongly echogenic fold structure could be seen inside, and a strongly echogenic circular structure could be detected on the adjacent caudal side. The internal part showed weak echogenicity, which is a characteristic ultrasound image of the intestinal tract.
