Our hospital offers ultrasound (sonogram) examinations as a non-invasive procedure to evaluate internal organs. Ultrasound can be used to examine the abdominal organs, reproductive organs and heart. If the heart is being examined, the ultrasound is called an echocardiogram. Many times both radiographs (X-rays) and ultrasound of your pet are recommended for best evaluation of your pet's problem. X-rays show the size, shape and position of the organs and the ultrasound allows your veterinarian to see the internal structure of the organs. Ultrasound is very non-invasive and well tolerated by most pets. Most pets do not require sedation or anesthesia but this depends on their temperament. The hair on the abdomen must be clipped to allow adequate visualization during ultrasound. Gel is then placed on the abdomen and the ultrasound probe is moved methodically over the surface of the abdomen to record images of each organ. If your veterinarian has concerns about their initial ultrasound examination, they may refer you to a specialty veterinary hospital for further evaluation by a specialty ultrasonographer.
