Veterinary Neurology

If your pet has a neurological issue, the board certified specialist at Columbia River Veterinary Spcialists is trained and equipped to handle it. Our neurologist and supporting team are experts at diagnosing and treating disorders of the brain, spinal cord and peripheral nerves.

Our neurologist can make a determination as to whether cancer cells are present, and will meet with you to discuss the course of the disease, additional recommended diagnostics, treatment options, side effects and the ultimate prognosis. We believe one of the keys to successful treatment is clear communication between our team and you—and we’ll ensure you have all the information you need as you work with us to choose the best course of care. Common disorders that are treated include:

  • Caudal Cervical Sponydylomyelopathy (Wobbler’s disease)
  • Caudal Occipital Malformation Syndrome or Chiari-like Malformation
  • Head Trauma or Traumatic Brain Injuries
  • Infectious Diseases Involving the Nervous System
  • Tumors of the Brain and Spinal Cord
  • Vestibular Disease (balance disorders)
  • Weakness or Paralysis
  • Seizure Disorders or Epilepsy
  • Encephalitis/Meningitis
  • Hydrocephalus
  • Intervertebral Disc Disease
  • Lumbosacral Disease
  • Movement Disorders
  • Narcolepsy/Cataplexy
  • Neuromuscular Disorders
  • Spinal Pain
  • Stroke Disorders


We are delighted to announce our 1.5T High Field Hallmarq Veterinary Imaging, Inc. MRI unit is ready to provide state-of-the-industry diagnostic capabilities for small animal patients.

Our new MRI is the first installation of the 2nd generation small animal MRI system in the Portland/Vancouver area and it is twice the speed of our previous in-house unit. The technology, developed exclusively for the veterinary market, will provide diagnostic capability at comparable speeds and accuracy to MRIs utilized in human medicine.

Dr. Dan Krull states that there is a distinct advantage to the Hallmarq Small Animal MRI. “Most vet clinics that have an MRI, use a model that is developed for humans but retrofitted for small animals. Our MRI is designed and manufactured with veterinary specific coils, patient bed, software and specifically formatted sequences for cats and dogs.” The MRI has five different coils to accommodate the significant variability in size of our patients. This includes a 1 meter long V-shaped spine coil, allowing for easy imaging of large breed dogs. This coil fits closely to most pets as they enter the MRI, providing a 20 percent better signal than a flat bed made for humans. The Hallmarq system can also run two coils simultaneously, which improves image quality and allows clearer imaging of difficult to reach areas on many pets.
