What You Should Know About Ultrasound Costs
Not all vets do ultrasounds in-house. Many refer to a traveling sonographer or specialist, which adds a referral fee. If your regular vet charged $350 for an ultrasound, $100-$150 of that may be the sonographer's fee. This is normal.
Abdominal ultrasound checks the liver, spleen, kidneys, bladder, and intestines. It doesn't require sedation in most cases. Cardiac ultrasound (echocardiogram) checks heart structure and function and often requires a specialist cardiologist. Expect cardiac ultrasounds to cost $400-$600.
Ultrasound is better than X-ray for soft tissue problems (organ masses, fluid, bladder stones). X-ray is better for bones and lungs. If your vet ordered both ($500-$700 total), it's because they're looking at different body systems. One doesn't replace the other.
