Is Something Wrong? How X-Rays and Ultrasounds Help Us See Inside Your Pet

When your pet isn’t feeling well- whether they’re limping, not eating, or just acting off- it can leave you feeling helpless. Since they can’t tell us what’s wrong, veterinarians rely on advanced diagnostic tools like X-rays and ultrasounds to uncover what’s happening beneath the surface. These imaging methods provide essential information to help us make accurate diagnoses and build effective treatment plans.

At Burlington Veterinary Center in Burlington, Connecticut, we use these tools every day to provide answers when pets can’t explain their symptoms. With on-site digital radiology, in-house ultrasound, and a full-service laboratory, our diagnostic capabilities are designed to deliver fast, precise results while keeping pets comfortable. Here’s how X-rays and ultrasounds work, what they show us, and why they matter for your pet’s health.

X-rays vs. Ultrasounds in Veterinary Medicine

Though both are diagnostic imaging tools, X-rays and ultrasounds serve different purposes.

  • X-rays (radiographs) capture still images using electromagnetic radiation. They’re ideal for viewing bones, teeth, and dense organs like the heart and lungs.
  • Ultrasounds use high-frequency sound waves to create real-time images of soft tissues such as the liver, kidneys, bladder, and heart.

Think of an X-ray as a snapshot, while an ultrasound is more like a live video. Your veterinarian will decide which tool- or combination of tools- best suits your pet’s symptoms.

When Your Pet Might Need Imaging

We often recommend imaging when pets show vague or concerning signs that need investigation. Some common reasons include:

Because these symptoms can stem from many causes, imaging helps us move from observation to diagnosis- so we can act quickly and effectively.

What X-rays Help Diagnose

X-rays give us a clear look at your pet’s skeletal structure and certain internal organs. They are especially useful for:

  • Fractures and joint problems: Essential for trauma cases and chronic issues like arthritis.
  • Foreign objects: If your pet has eaten something unusual, X-rays often reveal it.
  • Chest evaluations: Radiographs can identify lung disease, fluid accumulation, and changes in heart size.
  • Dental disease: Hidden problems like abscesses, resorbed roots, or bone loss are only visible with dental radiographs.

What to Expect During an X-ray

Your pet will be gently positioned for the image, and in some cases, light sedation may be used to keep them comfortable and still. The procedure is fast, completely painless, and radiation exposure is minimal.

When Ultrasound Is the Better Choice

Ultrasound is the go-to tool for examining soft tissues and real-time processes. At Burlington Veterinary Center, Dr. Esherick is trained in small animal ultrasonography and echocardiography, offering advanced on-site evaluations. Ultrasound is particularly helpful for:

  • Heart evaluations (echocardiograms): Ultrasound allows us to see heartbeats, valves, and blood flow in real time, which is crucial for detecting structural problems.
  • Abdominal imaging: We can assess the liver, spleen, pancreas, stomach, intestines, and kidneys for tumors, obstructions, or inflammation.
  • Urinary issues: Ultrasound reveals bladder stones, obstructions, and abnormal growths.
  • Pregnancy monitoring: It offers a safe, non-invasive way to track fetal development.

Ultrasound is also invaluable in emergencies- such as detecting internal bleeding or fluid accumulation- so treatment can begin immediately.

What to Expect During an Ultrasound

The area to be examined is usually shaved, and a water-based gel is applied. A probe is then gently moved over the skin to capture images. Ultrasounds are completely painless, and most pets don’t require sedation.

In-House Diagnostic Strengths at Burlington Veterinary Center

What sets Burlington Veterinary Center apart is the ability to combine multiple diagnostic approaches under one roof:

  • Digital radiology with review by board-certified radiologists.
  • Daily in-house ultrasound for immediate site-of-care diagnostics, including echocardiography.
  • Real-time biopsies and aspirates guided by ultrasound.
  • Full-service in-house laboratory with rapid bloodwork, cytology, and parasite testing.
  • Partnership with Idexx and other reference labs for specialized testing.

Having access to all of these tools in one place speeds up diagnoses and ensures continuity of care.

When to Ask Your Vet About Imaging

Here are some common signs that may signal the need for X-rays or ultrasound:

  • Sudden lameness or reluctance to move
  • Persistent vomiting or gastrointestinal distress
  • Chronic coughing or changes in breathing
  • Noticeable weight loss or decreased appetite
  • Swelling, bloating, or unexplained pain

If you notice these changes, it’s always better to ask sooner rather than later. Early imaging often leads to earlier treatment- and better outcomes.

How to Prepare for Your Pet’s Imaging Appointment

To make your visit as smooth as possible, bring the following:

  • A list of medications your pet is currently taking
  • Any recent lab results or health records
  • Notes on symptoms, including when they started and how they’ve changed
  • Photos or videos of concerning behaviors (such as limping or coughing)

For some abdominal ultrasounds, we may recommend withholding food for 8 to 12 hours beforehand. Water is typically fine. Contact us to confirm what’s right for your pet.

Frequently Asked Questions About Pet Imaging

Are X-rays safe for my pet? Yes. Veterinary X-rays use a very low dose of radiation and are only performed when necessary.

Will my pet be sedated? Sometimes. Sedation may be used if your pet is anxious, painful, or needs to remain still for a clear image.

How quickly will I know the results? Many results are available the same day. Complex cases may be reviewed by board-certified radiologists for additional insights.

Does ultrasound hurt? No. It’s completely non-invasive and usually well tolerated, especially in our Fear-Free environment.

Why Early Diagnosis Matters

Using X-rays and ultrasounds early allows us to:

  • Catch diseases before symptoms worsen
  • Develop targeted treatment plans
  • Reduce the need for invasive procedures
  • Improve outcomes and minimize long-term costs

When we can see what’s happening inside, we can act faster, treat more effectively, and help your pet feel better sooner.
