cross sectional imaging technique that uses a magnet 30,000 times the strength of the earth's gravity and advanced computers
to provide high quality diagnostic images.

are placed under general anesthesia to limit motion during the imaging studies. Procedure length varies from 30 to 90 minutes
depending on the area or areas evalated. Antenna like receiving coils are placed around the anatomical region evaluated to
acquire the images.
sectional MRI image of a dog's head at the level of the ears, performed because the pet had a head tilt and poor balance/difficulty
walking and falling to the side. The arrow points to a treatable infectious process filling the middle ear of this dog. This
infection is severe, but was not evident on physical exam because this part of the middle ear is surrounded by bone and the
tympanic membrane. MRI is ideal for producing high quality images of the deep soft tissue structures of the head, spine
and musculoskelatal system.
To the left is a CT scan slice through the chest and thoracic spine of a German Shepherd Dog with back pain.
The arrows on the CT scan show an an infected vertebral section in the pet's spinal column (the bone appears irregular and
"moth-eaten"). The infection was identified at the source of pain. A biopsy of the tissue was done after the scan
to identify the specific type of organism growing in the bone (a fungus) so that the correct anti-fungal medicine could be
started to treat this pet.
the left is a sagittal MRI image slice through a dog's knee. The pet's knee (stifle) was painful and a ruptured cruciate ligament
was suspected. However, the MRI shows the ligaments were not damaged, but a mass was present. A biopsy was necessary after
the MRI to identify the cell type of the tumor and determine the best treatment and most accurate prognosis. Identifying the
tumor early was helpful in providing a cure for this patient.
