Magnetic resonance imaging of the cervical spine repeated eight days after the initial magnetic resonance image performed on admission. Interval development of cord edema and infarction is seen from the C2 to T2 levels. (A) Sagittal T2 sequence. (B) Diffusion-weighted image. (C) Apparent diffusion coefficient image. The diffusion-weighted image and apparent diffusion coefficient image do not demonstrate the exact same level of involvement, with the apparent diffusion coefficient image showing signal changes slightly lower in the cervical spine than the diffusion-weighted image. Also, the diffusion-weighted image signal abnormality does affect somewhat the dorsal aspect of the cord. This reflects the often diffuse and collateral nature of electrical injuries.
