Our hospital offers Magnetic Resonance Imaging (MRI), an advanced form of diagnostic tool. Having an MRI scan is a non-invasive procedure similar to taking an x-ray. However, an MRI relies on a very powerful magnetic field to create an image of soft tissue and then uses a computer to process the resulting information.
MRIs are an important tool for diagnoses of certain conditions. This is because abnormal soft tissue displaces normal tissue, resulting in enlarged areas that may only be apparent in MRI images. MRI is extremely sensitive at showing areas of hemorrhage, for example, though it is not as good as a CT scan at evaluating bony changes or problems.
General anesthesia is required for an MRI, as any movement can impair the results, but the procedure is entirely pain free. MRI scans are often requested for pets that suffer seizures or behavior changes, or have difficulty walking, among other conditions.
