Application of veterinary B-ultrasound in canine spleen: When an animal is ill and suspected of having a spleen disease, the spleen can be examined by veterinary B-ultrasound and its size can be measured to compare whether the echo is enhanced or weakened, enlarged or reduced compared with the normal state. Through these, some diseases can be found, such as sepsis or toxemia, which will cause acute congestion of the spleen and enlargement of the entire spleen. If the spleen has focal echo abnormalities, veterinary B-ultrasound can be used to diagnose spleen cysts, hematomas, abscesses, tumors, focal necrosis and infarction. The echoes of these diseases are enhanced or weakened on veterinary B-ultrasound. Splenic rupture can be seen in splenic hematomas or free ascites in veterinary B-ultrasound images.

Application of veterinary B-ultrasound in the digestive system: Foreign bodies in the gastrointestinal tract are one of the most common diseases of the digestive system. Foreign bodies can be divided into four categories, namely: high-density, medium-density, low-density and thin objects. High-density materials show strong echoes on veterinary B-ultrasound, such as stones and glass balls. Medium-density materials show sub-strong echoes on veterinary B-ultrasound, such as rubber plugs, foam, plastic, etc., which are easier to diagnose. Low-density materials with weak echoes, such as cotton threads, balls of thread, and plastic bags, require a large amount to be diagnosed. Thin objects such as suture needles and thin metal wires are difficult to diagnose. Veterinary B-ultrasound intussusception has specific diagnostic value. It appears as a sausage-like strong echo band on the veterinary B-ultrasound image. Gastrointestinal leiomyoma is also a common disease in dogs. General diagnostic measures are difficult to diagnose. On the veterinary B-ultrasound ultrasound image, it appears as a large mass, an irregular protrusion growing on the intestinal wall, often including single or multiple strong echo areas, which is different from the gastrointestinal segment gas content.
