Pet Ultrasound

When Ultrasound Is the Right Next Step

X-rays reveal bones and gross structural changes, but evaluating soft tissue requires a different tool. Abdominal ultrasound uses sound waves to produce real-time images of internal organs, including the liver, spleen, kidneys, bladder, intestines, adrenal glands, and lymph nodes. It involves no radiation and is well-tolerated by most pets without sedation.

Ultrasound is typically recommended when a pet presents with unexplained weight loss, vomiting, diarrhea, abdominal pain, changes in urination, or an abnormality found on physical exam or X-ray. It is also used to investigate elevated blood test results, suspected masses, or abdominal fluid accumulation.

Unlike static imaging, ultrasound captures organ texture, wall thickness, fluid movement, and vascular patterns in real time.

What the Procedure Involves

Abdominal ultrasound at Petfolk is designed to be as comfortable as possible for your pet. The procedure is non-invasive and takes 20 to 45 minutes, depending on the evaluation. Sedation is not required in most cases. Pets are asked to fast for a few hours beforehand to minimize gastrointestinal gas, which can affect image quality. Results are reviewed the same day.

What does an abdominal ultrasound check for in pets? 

It evaluates the liver, spleen, kidneys, bladder, adrenal glands, intestines, and lymph nodes. It can detect masses, fluid, organ enlargement, wall thickening, stones, and abnormalities not visible on X-rays.

Does my pet need to be sedated? 

Not typically. Most pets tolerate the procedure awake or with light restraint. Sedation may be used for anxious or painful patients, but it is not routine.

How should I prepare my pet?

Fast your pet for 6 to 8 hours before the appointment. Food and intestinal gas can reduce image quality. Water is generally fine until arrival.

How long does it take? 

Most abdominal ultrasounds take 20 to 45 minutes, depending on the number of structures being evaluated and the patient's cooperation.

Will fur need to be shaved? 

A small area over the abdomen is clipped to ensure proper transducer contact. The area is minimal and grows back.

When is an ultrasound recommended over X-rays? 

X-rays are better suited for bone and gross organ size. Ultrasound is used to assess organ texture, detect fluid, evaluate masses, or investigate soft tissue in more detail.

Can ultrasound detect cancer? 

It can identify masses and structural changes that may suggest a tumor, but a definitive diagnosis requires tissue sampling, such as a fine-needle aspirate or biopsy. Ultrasound is often the first step in that process.

Is ultrasound safe? 

Yes. It uses sound waves rather than radiation, making it appropriate for pets of all ages, including young animals, pregnant females, and those with compromised health.

What happens after the ultrasound? 

Findings are reviewed the same day. Next steps may include follow-up bloodwork, tissue sampling, specialist referral, or a treatment plan if a diagnosis is confirmed.

Can ultrasound be combined with other diagnostics? 

Yes. It is commonly used alongside bloodwork, urinalysis, and X-rays. In some cases, it is also used to guide fluid or tissue sampling during the same appointment.
