FIG 2. A–E, Cross-sectional T1-weighted (800/22/6) (A) and T2-weighted (2000/80/4) (B) images of rat spinal cord 1 week after injection show abnormal heterogeneous signal in the gray matter, worse on the left, with associated loss of normal gray/white differentiation (curved arrow). Corresponding ADC maps in the read (C) and slice-select (D) axes show two areas of increased signal (arrows) in both axes, corresponding to the two cavities partially filled with cellular debris on the histopathologic specimen (arrows, E). The increased neuronal damage on the left is seen as a relative decrease in size of the dorsal gray matter on the left side of the spinal cord (arrowhead)
