From: Timing of diffusion tensor imaging in the acute spinal cord injury of rats

Conventional magnetic resonance imagings from all the groups at 6 h after injury.
The T1-weighted images (T1WI) depicted less noticeable changes of the signal intensity in SCI (B–D). In T2-weighted images (T2WI) of SCI, injured groups showed a hypointense region within the central cord parenchyma, surrounding a hyperintense region corresponding to the site of contusion (F–H).
