[Abstract] Objective: To understand MRI characteristics of hirayama disease’s (HD).Materials and Methods: Five patients with HD were scanned by MR on the conventional and the flexion position. The findings were analyzed.Results: On the conventional position, 5 cases presented slight atrophy of lower cervical cord, 1 case showed upper thoracic cord involvement. On the flexion position, the lower cervical cords showed antedisplacement. Widened spinal epidural space within abnormal strip shadow in all the cases.Conclusion: The conventional and the flexion position of the neck condition on MRI has the characteristics.
