When Your Pet Might Need a CT Scan
Hearing that your pet may need a CT scan can sound a little worrying at first. For many owners in Streatham and South London, it is not something they have come across before, so it is natural to have questions. What is a CT scan? Why might it be recommended? And what does it help us find?
At Streatham Hill Vets, we know that clear information can make a stressful situation feel much more manageable. A CT scan is simply one of the advanced diagnostic tools we may use when we need a more detailed picture of what is happening inside your pet’s body. It can help us investigate certain symptoms more thoroughly and plan the most appropriate treatment.
This article explains when your pet might need a CT scan, how it fits into the diagnostic process, and when to speak to your vet. This article is intended for general guidance only. If your pet is unwell or showing concerning symptoms, please contact your vet for professional advice.
What is a CT scan?
A CT scan, short for computed tomography scan, is a type of imaging that creates highly detailed cross-sectional pictures of the inside of the body. You can think of it as taking many thin “slices” of an area, which can then be viewed in much more detail than a standard X-ray.
While X-rays are still very useful, a CT scan can sometimes show structures more clearly, especially complex areas such as the head, chest, spine, joints and nasal passages. This can be very helpful when we are trying to understand the cause of a pet’s symptoms or plan surgery more accurately.

Why diagnostics matter
When a pet is ill, there is not always an obvious answer just from looking at them. A physical examination gives us an important starting point, but some problems require extra tests to reach a clearer diagnosis. Diagnostics are the tools we use to investigate symptoms and build a fuller picture of your pet’s health.
Depending on your pet’s signs, diagnostics may include:
- Physical examination and history taking
- Blood tests
- Urine tests
- X-rays
- Ultrasound
- CT scanning
Not every pet needs advanced imaging, and we would only recommend a CT scan when it is likely to provide useful information. Our aim is always to choose the most appropriate tests for your pet’s individual needs.
You can find out more about the wider care we offer on our services page and our advanced surgery and medicine page.
When might a CT scan be recommended?
A CT scan may be recommended when symptoms are ongoing, difficult to explain, or when we need more detail than other imaging methods can provide. Below are some common situations where it may help.
Ongoing lameness or joint problems
If your dog, cat or small pet has persistent lameness, pain on movement, or a suspected bone or joint problem, a CT scan may help us assess the area in more detail. It can be particularly useful for looking at complex joints and tiny bony structures that may not be easy to evaluate on standard X-rays.
This may be appropriate if your pet:
- Has been limping for some time
- Seems painful when walking, running or jumping
- Has had an injury that needs further assessment
- May need surgical planning
Breathing difficulties or nasal problems
Pets with noisy breathing, ongoing nasal discharge, sneezing, or suspected airway problems may sometimes benefit from CT imaging. It can help us look closely at the nose, sinuses and upper airways.
This is especially relevant in some flat-faced breeds, where airway shape may affect breathing. If needed, we may also discuss other related services, such as our BOAS grading clinic, which assesses breathing issues in brachycephalic, or flat-faced, dogs.
Head, ear or dental concerns
Some problems affecting the head can be difficult to assess from the outside. CT scans may be used to investigate:
- Chronic ear disease
- Dental disease below the gumline
- Swelling of the jaw or face
- Unexplained pain around the head
Because the structures in this area are small and closely packed together, detailed imaging can be very helpful.
Spinal or neurological symptoms
If a pet is showing signs that could involve the spine or nervous system, such as weakness, wobbliness, neck pain or difficulty walking, advanced imaging may be part of the investigation. A CT scan can give us a clearer picture of the bones of the spine and surrounding structures.
In these cases, early assessment is important. If your pet suddenly seems unable to walk, is collapsing, or is in severe pain, please seek urgent veterinary advice straight away. Our emergency vetcare information can help if you need urgent support.
Suspected masses, internal problems or surgical planning
In some cases, a CT scan may be used to investigate a lump, swelling or suspected internal abnormality, or to help plan a procedure in the safest and most precise way possible. Detailed imaging can be particularly useful before certain operations, including some minimally invasive procedures. You can read more about our keyhole surgery service if this is something your vet has discussed with you.
What happens before a CT scan?
Before recommending a CT scan, we would usually carry out a full clinical examination and often some first-line tests as well. This may include blood tests or X-rays, depending on your pet’s symptoms. In many cases, CT is used when we need more information after these initial steps.
We will talk you through:
- Why the scan is being recommended
- What area we need to image
- Whether any other tests are advised first
- Any likely costs and next steps
If you would like information about fees, you can view our prices page. We also offer information on 0% finance in appropriate cases.
Will my pet need sedation or an anaesthetic?
CT scans require pets to stay very still so the images are clear. Because of this, many pets need sedation or a general anaesthetic. We understand that this can be a concern for owners, but your pet would be carefully assessed beforehand and monitored closely throughout.
We will always discuss the plan with you in advance and explain what to expect on the day. Your pet’s safety and comfort are our priority at every stage.
How can owners spot when something might need investigating?
One of the most helpful things owners can do is notice changes early. You know your pet best, and small changes in behaviour, movement or comfort can be important.
Please book a veterinary appointment if your pet has:
- Ongoing limping or stiffness
- Breathing changes or noisy breathing
- Repeated sneezing or nasal discharge
- Balance problems or difficulty walking
- Persistent pain or sensitivity when touched
- A swelling, lump or change in shape
- Symptoms that are not improving as expected
Routine care also plays a valuable part in early detection. Regular health checks and preventative healthcare can help us pick up concerns sooner, before they become more serious.
Does every pet with these symptoms need a CT scan?
No. A CT scan is only one possible diagnostic tool, and many pets with the signs above will not need one. In some cases, a physical examination, blood tests, trial treatment, X-rays or ultrasound may be enough. The right diagnostic plan depends on your pet’s symptoms, age, species, medical history and what we find during the consultation.
Our role is to guide you through those options clearly and honestly, so you can make informed decisions about your pet’s care. If you would like to know more about our team and approach, please visit About Us or find out why owners choose us.
