Magnetic resonance imaging is a powerful diagnostic tool that involves the use of magnetic fields. It is used to obtain non-invasive digitalised anatomical images without harmful effects, as it does not use ionising radiation, which is necessary to perform X-Rays and Computerised Axial Tomography scans (CAT scans).
It also has the ability to produce images in any plane without having to reposition the animal. It also provides better spatial resolution, a greater range of tissue contrast and increased sensitivity to pathological processes.
Nuclear magnetic resonance imaging, or MRI, is a safe diagnostic examination that provides an image of the inside of the body that is clearer than the ones offered by many other diagnostic examinations. Magnetic resonance produces two or three dimension images. It does not use X rays. A contrast agent can also be used to help to see the images better.
Magnetic resonance imaging helps to detect illnesses and treat them early on. It provides detailed information quickly and can reduce the need for certain types of diagnostic surgery.
In general, the vet will recommend an MRI scan if he/she suspects the presence of intracranial injuries or spinal cord injuries, but the scope of the diagnosis provided by the MRI scan is much wider.
Below is a list of clinical settings where the use of resonance is recommended:
Localised pain and laminitis in any joint.
Evaluation of ligaments, tendons, menisci, cartilage, bones.
Surgical planning for osseous masses
Chronic fistulous tracts.
