The Advanced Veterinary Care Group uses the Vet-MR for our magnetic resonance imaging needs. Magnetic resonance imaging (MRI) is done when other standard methods of imaging such as radiographs and ultrasound are not adequate to demonstrate the problem. The Vet MR is an “open” MRI system specifically designed for veterinary patients.

What is Vet MR?
Magnetic Resonance Imaging (MRI) uses a very strong magnetic field to align the natural spinning of water molecules within body tissues. MR images are formed by tiny radiofrequency signals generated as the nuclei spin. The molecular alignment that occurs on the sub microscopic level cannot be felt and has no known harmful effects. The radio signals are collected by small antennae, called receiving coils placed outside the patient near the area we are interested in evaluating. An advantage of MRI is its ability to produce images that are simple cross- sections as well as from any other angle with equal resolution. MRI scans give the best soft tissue contrast of all the imaging modalities.
What are possible applications for MRI in Veterinary Medicine?
Neural tissue disorders – brain, spinal cord, peripheral nerves
- MRI is the best modality to evaluate the nervous system. It is non-invasive and has the best contrast resolution of all imaging modalities.
- MRI can be used not only to examine bony structures; it is superior to all other imaging modalities when evaluating muscles, tendons and ligaments.
Soft tissue tumors, abscesses, draining tracts
- MRI is excellent in evaluating extent and margins of soft tissue lesions. In case of chronic wounds and draining tracts, it will help identifying foreign bodies within the wound. It will allow evaluation of bone involvement, assessment of resectability of a lesion and diagnosis of regional lymph node enlargement.
Nasal/ paranasal sinus, orbital and ear disorders
- MRI is very useful when evaluating patients with signs of nasal disease, disorders of the orbit and disorders of the ear. It is the modality of choice when extension of the disease process into the brain is suspected.
