Pet Ultrasound in Oakland, TN

Some things a physical exam and X-rays can’t show on their own. At Main Street Animal Clinic, ultrasound fills in that gap—giving our team real-time, moving images of your pet’s internal organs and soft tissue structures without the need for surgery or sedation

How Pet Ultrasound Works

Ultrasound uses high-frequency sound waves to create images of internal structures. A handheld probe is moved over the skin surface, and the returning sound waves are converted into a live image on screen. The procedure is painless and doesn’t use radiation—making it safe for repeated use, including in pregnant animals.

The area being imaged is typically shaved or clipped so the probe can make good contact with the skin. Most pets tolerate the procedure well while lying calmly on a padded surface. Light sedation is occasionally used for anxious patients or when very precise imaging is needed, but it isn’t required for most ultrasound exams.

What Ultrasound Can Show

Ultrasound excels at evaluating soft tissue detail—something X-rays aren’t designed to do with the same resolution. The two imaging modalities are often complementary, and we may recommend both depending on your pet’s situation.

Abdominal organs
We can evaluate the liver, spleen, kidneys, adrenal glands, bladder, stomach, intestines, and lymph nodes for size, shape, texture, and the presence of masses or fluid. Abdominal ultrasound is one of our most commonly used diagnostic tools for pets with vomiting, weight loss, changes in urination, abdominal distension, or unexplained lethargy.

Cardiac imaging (echocardiography)
Cardiac ultrasound lets us evaluate the heart’s chambers, valves, and wall motion in real time. It’s particularly useful when a heart murmur is detected during a wellness exam, and we need to understand its cause and severity. We can assess whether heart disease is present, how advanced it is, and whether it’s affecting the heart’s ability to function effectively.

Pregnancy confirmation and monitoring
Ultrasound is the most reliable way to confirm pregnancy in dogs and cats and to monitor fetal development. It can detect heartbeats as early as three to four weeks into gestation and provide an estimate of litter size, though X-rays later in pregnancy give a more accurate count of puppies or kittens.

Guided procedures
Ultrasound can be used to guide certain diagnostic procedures, such as fine needle aspirates of masses or fluid collection from the abdomen or chest. Real-time imaging helps ensure the needle is precisely positioned, improving both safety and sample quality.

Urinary tract evaluation
Bladder wall thickening, bladder stones, and urinary tract masses are often visible on ultrasound. When lab testing suggests a urinary issue but X-rays don’t provide a complete picture, an ultrasound can help clarify what’s going on.

Ultrasound vs. X-Rays—Which Does My Pet Need?

The two imaging tools serve different purposes and are often used together. X-rays are best for evaluating bone, air-filled structures like the lungs, and overall organ position and size. Ultrasound provides detailed soft tissue information—organ texture, internal structure, fluid presence, and real-time motion.

If your pet has a suspected fracture, we’ll reach for X-rays first. If your pet has abdominal symptoms or a suspected mass, an ultrasound often gives us more useful information. In many cases, both are used together to build a complete diagnostic picture before making treatment decisions, particularly when soft tissue surgery is being considered.

When We Commonly Recommend Ultrasound

Ultrasound is useful in a wide range of situations. We commonly recommend it when a pet is
experiencing:

Vomiting, diarrhea, or unexplained weight loss
Abdominal distension or pain on palpation
Increased thirst and urination
Changes in urination habits or suspected bladder issues
A heart murmur detected during a physical exam
Lethargy or appetite changes without a clear cause
A palpable abdominal mass or abnormal finding on X-ray
Trauma with suspected internal injury
Pregnancy confirmation or monitoring

Pet Ultrasound FAQs

Does my pet need to be sedated for an ultrasound?

Most pets don’t require sedation for a routine ultrasound exam. We ask that your pet lie still on their side or back while the probe is moved over the area being imaged. Anxious pets or those in significant pain may benefit from light sedation to allow for a more thorough exam. We’ll assess your pet’s temperament and comfort level before the procedure.

Does my pet need to fast before an ultrasound?

For abdominal ultrasounds, fasting for several hours beforehand is usually recommended. Food in the stomach and gas in the intestines can interfere with image quality. We’ll give you specific preparation instructions when we schedule the appointment.

Can ultrasound detect cancer in pets?

Ultrasound can identify masses, irregular tissue texture, enlarged lymph nodes, and other findings that may suggest cancer. However, imaging alone can’t confirm a cancer diagnosis—tissue sampling through fine needle aspirate or biopsy is typically needed for a definitive answer. Ultrasound can guide that sampling process and help us determine the best approach.

What's the difference between a regular ultrasound and a cardiac ultrasound?

A standard abdominal ultrasound focuses on the organs of the abdomen. A cardiac ultrasound (echocardiogram) is specifically focused on the heart—its chambers, valves, wall thickness, and pumping function. Both use the same underlying technology but require different probe positions, techniques, and interpretive expertise.

If your pet has a known or suspected heart condition, we can discuss whether echocardiography is the right next step.

Will I be able to see the images during the exam?

In most cases, yes. We’re happy to walk you through what we’re seeing on screen during the exam and explain the findings as we go. We’ll also review the results with you in detail before you leave.
