Cat & Dog MRI Scans For Spinal and Neurological Diagnosis
A cat and dog MRI is used to investigate complex spinal and neurological conditions that require detailed imaging. Magnetic resonance imaging (MRI) allows a clear assessment of the spinal cord and surrounding structures and is commonly recommended for IVDD in dogs, disc herniation in dogs, and spinal cord injury in dogs. This level of detail is particularly important in breeds such as a dachshund with IVDD or dogs presenting with weakness or paralysis in dogs.
MRI Scans for Dogs
Advanced Neurological & Soft Tissue Imaging
MRI is used to investigate complex neurological and spinal conditions in dogs that require a detailed assessment of soft tissue. MRI provides high-resolution images of the brain, spinal cord, nerves and surrounding structures that cannot be fully evaluated using X-ray or CT.MRI is most commonly recommended for dogs with suspected spinal or neurological disease.
When an MRI is recommended
MRI is used to assess conditions affecting the spine and nervous system, including:
- IVDD and intervertebral disc disease dog
- Disc herniation dogs with spinal cord compression
- Spinal cord injury in dogs
- Lumbosacral disease in dogs
- Cauda equina syndrome canine
- Paralysis in dogs
- Neurological signs in breeds such as a dachshund with IVDD
The level of anatomical detail provided by MRI enables clinicians to distinguish between surgical and non-surgical cases and plan appropriate treatment.
MRI is commonly used to diagnose:
- IVDD in dogs and acute disc extrusion
- Ruptured disc dog and spinal instability
- Slipped disc in a dog
- Spinal cord injury in dogs
- Osteosarcoma in dogs involving spinal or adjacent soft tissues
- Dog bone cancer with neurological involvement
- Selected thoracic or soft tissue conditions where detailed soft tissue contrast is required
What to expect during an MRI scan
MRI scans are performed under general anaesthesia to ensure image accuracy and patient safety. The procedure is non-invasive and does not use ionising radiation.
Throughout the scan, vital signs are closely monitored by trained anaesthesia staff. Once imaging is complete, the scans are reviewed by specialists and a detailed report is provided to the referring veterinarian.
Referral pathway
MRI scans are arranged through a referring veterinarian. Clinical history, neurological findings and any previous imaging are reviewed prior to booking to confirm MRI is the most appropriate diagnostic option.
Following the scan, results are communicated directly to the referring clinic to support ongoing case management.
Key notes for referring veterinarians
- MRI is the preferred imaging modality for spinal and neurological disease
- Essential for IVDD localisation and surgical planning
- Provides superior diagnostic detail compared with CT
- Supports timely, informed treatment decisions
Frequently Asked Questions
Is MRI safe for dogs?
Yes. MRI is non-invasive and does not involve radiation. Anaesthesia is required and is carefully monitored throughout the procedure.
Is MRI better than CT for spinal conditions?
MRI provides superior detail of the spinal cord, nerves and soft tissues, making it the preferred imaging modality for neurological disease.
What is IVDD in dogs?
IVDD, or intervertebral disc disease, occurs when a disc between the vertebrae bulges or ruptures and places pressure on the spinal cord. This can cause pain, weakness or paralysis and is commonly seen in breeds such as Dachshunds.
Can an MRI confirm a slipped or ruptured disc?
Yes. MRI can clearly identify disc extrusion or compression and determine whether surgical intervention is required.
Is an MRI necessary before IVDD surgery?
In most cases, yes. MRI allows accurate localisation of the affected disc and assessment of spinal cord compression, reducing surgical risk.
How long does an MRI take?
The scan typically takes 45–90 minutes. Including preparation and recovery, most dogs remain in the hospital for several hours.
How quickly are results available?
A full report is usually provided to the referring veterinarian within 24–48 hours, with urgent cases prioritised.
When is an MRI indicated in neurological cases?
MRI is indicated for dogs presenting with neurological signs suggestive of intracranial or spinal disease, particularly when detailed assessment of the spinal cord, nerve roots or soft tissues is required.
Why is MRI preferred for IVDD?
MRI provides superior visualisation of the spinal cord and intervertebral discs, allowing accurate localisation and characterisation of disc extrusion or protrusion. This information is essential for determining whether surgical or medical management is suitable.
Can MRI differentiate compressive and non-compressive spinal disease?
Yes. MRI allows differentiation between compressive lesions, inflammatory disease, neoplasia and degenerative conditions, supporting appropriate treatment planning.
Is an MRI required prior to IVDD surgery?
In most cases, an MRI is required to confirm the affected disc space, assess the degree of spinal cord compression and guide the surgical approach.
How does MRI compare to CT for neurological cases?
MRI provides superior soft-tissue contrast compared with CT and is the preferred modality for imaging the spinal cord, nerve roots, and brain. CT may be used for osseous assessment or where MRI is unavailable.
How are MRI scans performed?
MRI scans are performed under general anaesthesia to ensure patient immobility and image quality. Continuous monitoring is maintained throughout the procedure by trained anaesthesia staff.
What conditions are commonly diagnosed using MRI?
MRI is commonly used to diagnose IVDD, spinal cord injury, lumbosacral disease, cauda equina syndrome, spinal neoplasia and other neurological conditions.
How quickly are MRI results available?
A detailed report is typically provided to the referring veterinarian within 24–48 hours. Urgent cases are prioritised.
What is the cost of an MRI for dogs?
The cost of an MRI for dogs and cats varies depending on the region being scanned, the scan duration, and the reporting requirements. A clear estimate is provided prior to the procedure and includes:
- Anaesthesia and monitoring
- Imaging time
- Specialist interpretation and reporting
This allows owners and referring vets to make informed decisions before proceeding.
How are MRI referrals arranged?
MRI examinations are arranged via veterinary referral. Clinical history, neurological findings and previous diagnostics are reviewed prior to scheduling to confirm MRI is appropriate.
What information is included in the MRI report?
Reports include lesion localisation, interpretation of findings, differential diagnoses and recommendations for further management or referral where appropriate.
