By Sage Pet Hospital
When your pet isn’t feeling well, you usually have an idea of what you’re looking for.
Maybe your dog has been vomiting.
Maybe your cat isn’t eating.
Perhaps your pet has lost weight without any obvious reason.
Maybe bloodwork came back abnormal, and now your veterinarian needs to figure out why.
You go into the veterinary hospital expecting to investigate one particular problem.
But sometimes the most important thing an ultrasound finds is something nobody was expecting.
That’s one of the reasons veterinary ultrasound can be such a valuable diagnostic tool.
Ultrasound allows us to look inside the body in real time and evaluate organs and tissues that can’t always be fully assessed through a physical examination, bloodwork, or X-rays alone.
At Sage Pet Hospital, we use dog ultrasound, cat ultrasound, and other forms of pet ultrasound to investigate a wide range of medical concerns involving the abdomen and heart.
And sometimes, while we’re looking for one problem, we discover another.
That unexpected finding can completely change what happens next.
Symptoms Don’t Always Tell the Whole Story
One of the challenges of veterinary medicine is that many different diseases can cause the same symptoms.
Vomiting is a good example.
A dog may vomit because of something they ate.
Another dog may have gastrointestinal inflammation.
Another may have pancreatitis.
Another may have a foreign body.
And another may have a mass affecting the digestive tract.
The symptom is the same.
The underlying problem isn’t.
Cats can be just as difficult to diagnose.
A cat that isn’t eating may have gastrointestinal disease, kidney disease, liver disease, inflammation, pain, or another condition entirely.
Weight loss can have many different causes.
Increased urination can have many different causes.
Diarrhea can have many different causes.
This is why veterinary medicine can’t always stop at treating the symptom.
We have to ask why the symptom is happening.
The meeting transcript explains that ultrasound is used to evaluate concerns including liver, kidney, and spleen disease, chronic urinary problems, gastrointestinal upset, chronic vomiting, diarrhea, and decreased appetite.
The more possibilities there are, the more valuable it can be to have a diagnostic tool that lets us actually look inside.
Ultrasound Lets Us Look Beyond the Obvious
A physical examination gives us information we can’t get any other way.
Bloodwork gives us information about organ function and other changes happening within the body.
X-rays can provide valuable information about the abdomen and chest.
But ultrasound gives us another perspective.
Instead of looking only at the outside shape or density of an organ, we can evaluate its internal structure.
We can look at the liver.
The kidneys.
The spleen.
The gastrointestinal tract.
The urinary bladder.
The pancreas.
The adrenal glands.
Lymph nodes.
And other soft tissues within the abdomen.
The goal isn’t simply to take a picture.
Our ultrasound-trained team evaluates the organs from different planes to obtain as complete a picture as possible. Color Doppler can also be used to evaluate blood flow through organs.
That information can reveal changes that aren’t obvious from the symptoms alone.
Sometimes the Ultrasound Finds Something Completely Unexpected
This is one of the most interesting things about abdominal ultrasound.
You may begin the examination looking for one problem.
But because the abdomen contains so many interconnected organs, the scan can reveal something else that needs attention.
The meeting transcript includes several examples of this happening.
One particularly memorable case involved an older dog that wasn’t eating well.
The original concern was relatively broad.
The ultrasound was performed to investigate what might be happening in the stomach or abdomen.
Instead, the sonographer discovered a splenic tumor.
The spleen was ultimately removed, and the tumor was found to be non-cancerous.
The important part wasn’t that ultrasound magically diagnosed everything.
It was that the ultrasound allowed the veterinary team to see something they weren’t necessarily expecting to find.
Without looking, there would have been no way to know it was there.
Finding a Problem Before It Becomes an Emergency
Sometimes an unexpected finding is simply something that needs monitoring.
Other times, finding it early can make a much bigger difference.
In the splenic case discussed in the transcript, the ultrasound identified the problem while the pet was still stable enough to undergo surgery and recover well.
That’s one of the reasons we don’t think of ultrasound as simply a test for pets that are already critically ill.
It can also be a tool for finding problems while there is still time to make decisions.
That doesn’t mean every pet needs an ultrasound as a routine screening test.
It means that when there is a medical reason to investigate, ultrasound can provide information that may change the course of care.
Another Case Started With Vomiting and Diarrhea
Another case discussed during the meeting shows why combining diagnostic tools can be so important.
The pet was experiencing intermittent vomiting and diarrhea.
Radiographs were performed first.
Something concerning was seen.
An ultrasound was then performed to get a closer look at the intestines.
At first, the appearance raised concern for a possible foreign body.
That would have made sense.
Dogs and cats can swallow things they shouldn’t.
Chew toys, pieces of trash, and other objects can become gastrointestinal foreign bodies.
But surgery revealed something very different.
The pet actually had a large intestinal mass that was close to rupturing.
The ultrasound helped identify that something significant was happening inside the intestine.
The case also demonstrates why veterinary diagnostics sometimes require multiple steps.
An X-ray can tell us something.
An ultrasound can tell us something else.
Together, they may provide a much clearer picture than either test could provide alone.
Why X-Rays and Ultrasound Are Often Used Together
Pet owners sometimes ask which is better:
An X-ray or an ultrasound?
The answer isn’t always one or the other.
They evaluate different things.
The ultrasound team at Sage Pet Hospital specifically explained during the meeting that abdominal radiographs and ultrasound evaluate different tissue densities and therefore can complement each other in more involved cases.
An X-ray can provide an overall view of the abdomen and can be especially useful for certain types of abnormalities.
Ultrasound gives us the opportunity to examine soft tissues and organs in much more detail.
When a case is complicated, using both can help create a more complete picture.
That can be especially important when the initial symptoms don’t clearly point toward one diagnosis.
What Can a Pet Ultrasound Evaluate?
The abdomen contains many organs, and ultrasound can provide information about several of them during one examination.
Depending on the reason for the scan, your veterinarian may evaluate:
- Liver
- Gallbladder
- Kidneys
- Spleen
- Pancreas
- Stomach
- Intestinal tract
- Urinary bladder
- Adrenal glands
- Lymph nodes
- Abdominal fluid
- Masses or other abnormal structures
The exact areas evaluated depend on your pet’s medical history and why the ultrasound was recommended.
The scan isn’t necessarily identical for every patient.
A dog with abnormal liver values may require a different focus from a cat with chronic vomiting.
A pet with increased urination may need closer evaluation of the kidneys and bladder.
A pet with unexplained weight loss may need a broader abdominal examination.
The diagnostic question helps determine where we look.
The Spleen Deserves a Closer Look
The spleen is one of those organs that can sometimes be overlooked if an ultrasound isn’t performed carefully.
During the meeting, the ultrasound team specifically discussed the importance of imaging the entire spleen, including the portion located high near the stomach and ribs.
Why does that matter?
Because abnormalities can sometimes hide in areas that are more difficult to visualize.
A complete examination means making sure the entire organ is evaluated rather than assuming one easily accessible portion represents the whole spleen.
This is where experience and technique matter.
Ultrasound isn’t simply about having a machine.
The person performing the scan needs to know how to position the probe, how to obtain different views, and which structures deserve additional attention.
Ultrasound Is a Real-Time Examination
An ultrasound isn’t simply one photograph.
The sonographer moves the probe across the body and evaluates structures from multiple angles.
The Sage Pet Hospital ultrasound team describes collecting still images in different planes to create as complete a three-dimensional understanding of the organs as possible. Color Doppler can also be used to evaluate blood flow.
That means the examination is dynamic.
If something doesn’t look quite right, the sonographer can investigate it further.
They can change the angle.
They can take additional images.
They can examine the surrounding structures.
They can use Doppler when appropriate.
And if a finding remains unclear, the images can be reviewed with specialists.
Experience Changes What You Can Find
Ultrasound is highly dependent on the person performing it.
A machine can create an image.
It takes training and experience to know what that image means and what questions to ask next.
The meeting transcript explains that Sage Pet Hospital has specialty-trained ultrasound technicians and that the team continues to use outside radiologists and internal medicine specialists when a case is unclear or requires additional expertise.
That willingness to ask for another opinion is important.
Not every ultrasound finding is obvious.
Not every case fits neatly into one diagnosis.
Sometimes the best decision is to have another experienced set of eyes review the images.
The goal isn’t to prove that we already know the answer.
The goal is to get the most accurate answer possible for your pet.
What Happens When Something Concerning Is Found?
An ultrasound finding isn’t always the final diagnosis.
Sometimes it gives us enough information to begin treatment.
Other times, it tells us that additional testing is needed.
Depending on what is discovered, the next step may involve:
- Medication
- Dietary management
- Additional bloodwork
- Further imaging
- An endoscopy
- Surgery
- A specialist consultation
- Ultrasound-guided sampling
- Fine needle aspiration
- Biopsy
The transcript explains that ultrasound findings can lead to medical management, diet and medication trials, endoscopy, consultation with a traveling internist, or ultrasound-guided sampling of organs such as the liver, spleen, and lymph nodes.
That is why an ultrasound should be viewed as part of the diagnostic process rather than a magic answer machine.
It helps us determine what to do next.
Sometimes Ultrasound Can Help Us Sample an Abnormal Area
One of the advanced capabilities discussed in the meeting is ultrasound-guided sampling.
If the ultrasound reveals an area of concern, the team may be able to use the imaging to guide a fine needle aspiration or biopsy, depending on the situation.
The benefit is that we’re not simply guessing where an abnormal area is located.
The ultrasound helps us see it.
This can be particularly useful when evaluating structures such as the spleen, liver, or lymph nodes.
The transcript notes that Sage’s ultrasound-trained staff have advanced training that allows them to perform organ sampling and aspiration techniques that traditionally required specialty referral.
That can keep more of the diagnostic process closer to home.
Your Pet May Look Fine and Still Have a Problem
This is one of the most important things for owners to understand.
Pets don’t always show obvious symptoms when something is wrong.
A dog can still wag its tail while losing weight.
A cat can still sit in its favorite window while an internal disease is developing.
Some conditions don’t become obvious until they are advanced.
The ultrasound team described ultrasound as a useful way to identify subclinical or asymptomatic disease—problems that may be present even when they aren’t obvious during a physical examination.
That’s why changes such as unexplained weight loss, persistent gastrointestinal problems, increased urination, or abnormal bloodwork shouldn’t automatically be dismissed.
The pet may be telling you something before they look truly sick.
When Should a Veterinarian Consider a Dog Ultrasound?
There isn’t one symptom that automatically means your dog needs an ultrasound.
Instead, veterinarians look at the whole picture.
A dog ultrasound may be considered when there are concerns such as:
- Chronic or recurring vomiting
- Persistent diarrhea
- Unexplained weight loss
- Decreased appetite
- Abnormal liver values
- Abnormal kidney values
- Increased urination
- Chronic urinary problems
- Abdominal distension
- A suspected mass
- Concerning findings on X-rays
- Other unexplained abdominal symptoms
The meeting specifically identifies chronic weight loss, increased urination, and abdominal distension as examples of symptoms that may make the ultrasound team wish a pet had an ultrasound performed.
The recommendation still needs to come from your veterinarian after considering the individual patient.
When Should a Veterinarian Consider a Cat Ultrasound?
Cats can be particularly difficult to evaluate because they often hide signs of illness.
A cat ultrasound may be considered when a cat has:
- Chronic vomiting
- Diarrhea
- Weight loss
- Reduced appetite
- Abnormal bloodwork
- Urinary changes
- Kidney concerns
- Liver concerns
- An abdominal mass
- Persistent symptoms without an obvious explanation
Again, the goal isn’t to assume that ultrasound is necessary.
It’s to use the right diagnostic tool when the information already available suggests that looking deeper may help.
What Does the Appointment Look Like?
For many abdominal ultrasounds, your pet will spend several hours at the hospital.
The ultrasound team first considers the patient’s personality and behavior.
If a pet is calm, the scan may begin without medication.
If the pet is anxious, mild anti-anxiety medication may be used to make the experience more comfortable and help the team obtain better images.
Pets are positioned on their back or side using padded trays designed to help keep them comfortable.
The team then obtains images in different positions.
The patient may remain at the hospital for several hours so the ultrasound can be completed and additional diagnostics can be performed if needed.
This can also give the veterinary team time to review the images and determine whether additional consultation or testing is appropriate.
What If the Images Aren’t Clear?
Not every ultrasound is straightforward.
Sometimes the findings don’t immediately point toward one answer.
Sometimes multiple abnormalities are present.
Sometimes something looks suspicious but requires another opinion.
That’s when specialist consultation can become important.
The Sage Pet Hospital ultrasound team partners with radiologists and internal medicine specialists who can review images when additional expertise is needed.
This is particularly valuable because ultrasound interpretation takes extensive training.
It’s okay not to have every answer immediately.
What matters is knowing when to ask for help.
The Goal Isn’t to Find Something Wrong
It may sound strange, but a good ultrasound isn’t measured by how many abnormalities it finds.
Sometimes the best result is reassurance.
If your veterinarian is concerned about a particular organ and the ultrasound doesn’t show the suspected problem, that information matters.
It can help narrow the possibilities.
It can prevent unnecessary assumptions.
It can direct the veterinary team toward another diagnostic approach.
And if something is found, having that information can help create a more targeted plan.
The value is in the information.
Not simply in whether the scan is “normal” or “abnormal.”
Sometimes the Biggest Surprise Is the Most Important Finding
A pet comes in with one problem.
The veterinary team starts investigating.
An ultrasound is performed.
And something unexpected appears.
Maybe it’s a splenic nodule.
Maybe it’s an intestinal mass.
Maybe it’s an abnormality involving another organ.
Maybe it’s something that turns out to be benign.
Maybe it requires surgery.
Maybe it simply needs monitoring.
You can’t know what is happening internally until you look.
That is what makes ultrasound so valuable.
The memorable cases discussed during the Sage Pet Hospital meeting weren’t memorable because the technology was impressive by itself.
They were memorable because the technology helped the team see something that otherwise may have remained hidden.
In one case, an unexpected splenic tumor was found early enough for surgery and a successful recovery.
In another, ultrasound helped identify an intestinal problem that turned out to be a serious mass rather than the suspected foreign body.
Those are very different cases.
But they demonstrate the same principle.
Sometimes you have to look beyond the original symptom.
Keeping Advanced Diagnostics Closer to Home
Ultrasound used to be more commonly associated with specialty hospitals.
The meeting transcript explains that it was once a specialty technology that often required referral to internal medicine or a specialty clinic. Sage Pet Hospital has worked to bring more of that diagnostic capability into a local veterinary setting.
That matters for pet owners.
It can mean fewer referrals.
Less travel.
Fewer delays.
And more of the diagnostic process happening with a veterinary team that can communicate directly with you about your pet.
Sage Pet Hospital also offers cardiac ultrasound, with echocardiograms reviewed by a boarded cardiologist.
The Calmer the Pet, the Better the Diagnostic Experience
Ultrasound doesn’t need to be a frightening experience.
The team specifically emphasizes making the process as comfortable as possible.
Patient-specific positioning can be used when a pet has back pain or another physical limitation.
Anxiety medication may be considered for nervous patients.
The team can adjust the approach based on the individual pet.
As the ultrasound team explained during the meeting, a calmer pet makes it easier to obtain better diagnostic images.
That’s important because comfort and diagnostic quality can go together.
A pet that is comfortable is more likely to stay still.
A pet that stays still allows the team to collect better images.
Better images give the veterinary team more information.
Ultrasound Doesn’t Replace Your Veterinarian’s Judgment
Technology is an important part of veterinary medicine.
But it doesn’t replace clinical judgment.
The ultrasound is one piece of the puzzle.
Your veterinarian still needs to consider your pet’s history, symptoms, physical examination, bloodwork, radiographs, and other information.
The ultrasound team described ultrasound as a tool that helps rule different possibilities in or out rather than something that always produces a simple yes-or-no answer.
That is an important distinction.
Medicine isn’t always straightforward.
Sometimes an ultrasound answers the question immediately.
Sometimes it creates a better question.
Sometimes it tells us what test needs to happen next.
And sometimes it gives us reassurance that a feared problem isn’t there.
All of those outcomes are useful.
When Your Pet’s Symptoms Don’t Have an Easy Explanation
This is where a pet ultrasound can become especially valuable.
Your dog has been vomiting for weeks.
Your cat has lost weight.
Bloodwork isn’t normal.
Your pet’s abdomen looks distended.
Your veterinarian has found something unusual during the physical examination.
An X-ray raises another question.
At that point, guessing isn’t enough.
You need information.
Ultrasound can provide a detailed look at internal structures and help the veterinary team determine what deserves attention next.
At Sage Pet Hospital, our approach is to use that information alongside the rest of your pet’s medical picture.
We’re not looking for a reason to order another test.
We’re looking for a reason to understand your pet better.
Sometimes the Answer Is Where You Least Expect It
The original symptom isn’t always the final diagnosis.
That’s something pet owners should keep in mind when their veterinarian recommends an ultrasound.
The test isn’t necessarily being ordered because your veterinarian already knows what’s wrong.
Sometimes it’s being recommended because they don’t know yet.
That’s the point.
Ultrasound gives us an opportunity to investigate.
It can help identify disease.
It can help rule out possibilities.
It can help guide sampling.
It can help determine whether surgery or additional diagnostics are necessary.
And sometimes, it can reveal something completely unexpected.
Those surprises aren’t always bad news.
In some cases, they are exactly what allows a pet to receive care sooner.
At Sage Pet Hospital, we believe that having more information gives pets and their families more options.
If your dog or cat has unexplained symptoms, abnormal bloodwork, persistent gastrointestinal problems, urinary changes, weight loss, abdominal concerns, or another issue that hasn’t been fully explained, talk with your veterinarian about whether a dog ultrasound, cat ultrasound, or broader pet ultrasound could help provide the missing piece.
