Veterinary Ultrasound is a non-invasive, state-of-the-art technology that we use here at Pet Dominion in Rockville. The technique uses sound waves to painlessly examine specific internal organs, primarily the heart and abdominal organs. It is commonly used to evaluate bladder conditions such as cystitis, stones and to obtain guided sterile samples of urine. You may want to have an ultrasound performed on your older dog or cat to evaluate the size, shape and consistency of the abdominal organs in case there are early signs of tumors or disease.
