Magnetic resonance images of the thoracolumbar spine of an intact 6-month-old female giant schnauzer dog fed an unbalanced homemade diet. A — Sagittal T2-weighted image of the thoracolumbar spine showing an increase in size of the spinal cord from L2 to L5, with an associated increased medullary T2 signal intensity. The L4 vertebral body is shortened with a non-uniform T2 signal intensity and multifocal linear areas of low T2 signal intensity (arrow). Within the epaxial muscles surrounding the vertebral body there is a moderate increase in T2 signal intensity. Multiple other vertebral bodies are mildly misshapen and have inhomogenous T2 signal intensity and multifocal linear low signal intensities attributed to compression fractures. B — Transverse T2-weighted image at the level of L4 showing narrowing of the vertebral canal with attenuation of the subarachnoid space and loss of epidural fat. C — Transverse T2-weighted image at the level of L2 showing no attenuation of the subarachnoid space.
