What a Pet Radiology and Ultrasound Shows

Ultrasound is an imaging technique that uses sound waves and echoes to create moving images of the structures inside your pet’s abdomen. This allows us to evaluate organs, tissues, fluid, masses, and other internal changes as they appear in real time. Radiology, also known as digital X-ray imaging, helps us evaluate bones, joints, the chest, and the overall size, shape, and position of internal organs. It can reveal fractures, arthritis, lung abnormalities, swallowed objects, bladder stones, and other conditions that may not be visible during a physical examination.

Unlike a standard X-ray, ultrasound can give us a closer look at the shape and texture of many soft tissues. It is especially useful when we need more detail about the liver, spleen, kidneys, bladder, stomach, intestines, or other abdominal structures.

Radiology and ultrasound provide different types of information and are often used together. X-rays offer a broad view of bones and internal structures, while ultrasound provides more detailed, real-time images of soft tissues. Combining both methods can help our veterinary team develop a clearer understanding of your pet’s condition and recommend the most appropriate next steps.

When We May Recommend an Radiology and Ultrasound

We may recommend an ultrasound when blood work, physical examination findings, or ongoing symptoms suggest that more information is needed. The goal is to look beyond the surface and determine whether an internal problem may be contributing to your pet’s condition.

Our Veterinarian also recommend digital radiology when we need to evaluate bones, joints, the chest, organ size, swallowed objects, or other internal changes that may be visible on an X-ray.

Common reasons for recommending pet imaging in Avondale include:

  • Abnormal blood work values
  • Vomiting or diarrhea that is not improving
  • A distended or painful abdomen
  • Irregular findings during abdominal palpation
  • Follow-up after unusual X-ray results
  • Suspected masses, fluid, or organ changes
  • The need to collect cytology samples

An radiology and ultrasound does not always provide every answer on its own. In many cases, we use it alongside lab testing, radiographs, and a complete physical exam to build a clearer diagnostic picture.

Evaluating Ongoing Vomiting or Diarrhea

Vomiting and diarrhea can result from many causes, including dietary problems, inflammation, obstruction, infection, organ disease, or abnormal tissue growth. When symptoms continue despite treatment, imaging can help us look for a deeper reason.

Ultrasound allows us to examine the stomach and intestines for thickening, abnormal movement, foreign material, fluid, or other changes. This can help us decide whether medical treatment should continue or whether additional testing or intervention may be necessary.

Investigating Abnormal Blood Work

Blood tests can reveal that an organ may not be functioning normally, but they do not always show the physical cause. Ultrasound helps us evaluate the appearance of the organs connected to those abnormal values.

For example, we may examine the liver, kidneys, spleen, or bladder after changes are found in blood or urine results. Combining imaging with in-hospital lab work for dogs and cats often helps us move from a general concern to a more focused treatment plan.

Confirming Findings Seen on X-Rays

Digital radiography for pets is extremely helpful for evaluating bones, the chest, abdominal size, and certain types of foreign material. However, X-rays may show that something looks unusual without revealing exactly what the tissue is or how it is structured.

An ultrasound can provide a closer look at an area first identified through radiography. By using both methods together, we can compare findings and better understand whether a change involves an organ, fluid pocket, mass, intestinal section, or another soft tissue structure.

Real-Time Abdominal Imaging

One of the main advantages of ultrasound is that it shows movement as it happens. We may be able to observe intestinal motion, bladder contents, blood flow patterns, or fluid moving within the abdomen.

This real-time view gives us information that a still image cannot always provide. It can be especially helpful when we are evaluating sudden abdominal swelling, pain, irregular organ shape, or a suspected internal obstruction.

Collecting Cytology Samples

In some cases, an ultrasound helps guide the collection of a small sample from a mass, organ, or area of fluid. These samples can then be examined under a microscope to look for abnormal cells, inflammation, infection, or other changes.

Ultrasound guidance improves accuracy by allowing us to see the target area while the sample is collected. Whether this step is appropriate depends on the location, your pet’s condition, and the information we need to make a diagnosis.

What to Expect During the Appointment

For many abdominal radiology and ultrasound exams, a small area of fur may need to be clipped so the probe can make good contact with the skin. A special gel is then applied, allowing the sound waves to travel properly and create a clearer image.

Most pets tolerate the procedure well, although some may need mild sedation if they are anxious, painful, or unable to remain still. We will explain any preparation instructions before the visit, including whether fasting may be recommended.

Why In-Hospital Diagnostics Matter

Having access to ultrasound, radiology, digital radiography, and in-hospital laboratory testing allows us to investigate concerns more efficiently. Instead of relying on a single test, we can compare different types of information and choose the next step based on the full picture.

This coordinated approach can be especially important when a pet is seriously ill or not responding to treatment. Faster access to useful diagnostic information may help us begin appropriate care sooner and reduce unnecessary delays.

Frequently Asked Questions


No. Radiology and Ultrasound is generally noninvasive and painless. Some pets may feel mild pressure from the probe, but most tolerate the exam comfortably.


Usually not. Some pets may need mild sedation if they are very anxious, painful, or unable to stay still long enough for clear images.


Each test provides different information. X-rays are useful for bones, chest structures, and overall abdominal patterns, while ultrasound gives more detail about soft tissues and organ movement.


Preparation varies, but fasting may be recommended for certain abdominal studies. We will provide specific instructions based on your pet’s condition and the type of imaging planned.


Ultrasound can identify suspicious masses or organ changes, but it usually cannot confirm cancer by appearance alone. Cytology, biopsy, or additional testing may be needed.


We discuss findings as soon as the exam and image review are complete. The exact timing may vary if samples or outside interpretation are also required.
