FIG. 2.

Sagittal (A) and transverse (B, C, D) T2-weighted 3.0T magnetic resonance images of the thoracolumbar spinal cord from a dog with an acute sensorimotor complete injury caused by an intervertebral disc herniation. At the T13-L1 vertebral junction (white arrows), there is severe extradural spinal cord compression caused by herniated intervertebral disc material. There is normal spinal cord proximal to the lesion (B), severe spinal cord compression at the lesion epicenter (C), and T2 hyperintensity within the spinal cord immediately caudal to the lesion (midbody of L1) (D).
