Magnetic resonance imaging (MRI) is an imaging technique that uses nuclear resonance. It is non-invasive and non-irradiating unlike CT scans, and therefore safe for the patient. MRI is a fundamental technique in neurology insofar as it offers a better understanding of convulsions, paralysis, balance disorders, awareness disorders/behavioral changes. This technique has become a pillar in other fields of medicine like oncology, otology, ophthalmology, and for surgery of soft tissue.

MRIs are exclusively performed by two specialized veterinarians using a high-end machine (3 Tesla). This procedure is performed under general anesthesia to ensure that the patient does not move. Since the exam is painless, the anesthesia is relatively light and is usually compatible with most of the potential illnesses of the patient.
