A 56-year-old man admitted following a fall, with central cord syndrome. A, T2-weighted image shows a cord contusion (arrowhead) posterior to the C4-5 disk space. Ellipsoid representation of the tensor of the axial cervical cord of the patient and healthy volunteer at corresponding anatomic levels of the upper cord (B), adjacent to the contusion (C), cord contusion (D), and the lower cord (E) shows abnormal ellipsoid representation of the cord at and away from the cord contusion, where the conventional MR imaging shows no signal-intensity abnormality
