Medullary Cone Movement in Subjects with a Normal Spinal Cord and in Patients with a Tethered Spinal Cord

Abstract

Prone MR imaging has no additional value when the supine MR image has clearly shown the cause of tethering or in patients who have undergone tethered cord surgery, but it can provide additional information in patients clinically suspected of having a tethered cord and in whom supine MR imaging depicted no abnormalities.
