The hyperintensity extended up to the upper thoracic level in 13 of the 16 patients (Figs 1,3,4). On axial MR, the hyperintensity involved the central cord, both gray and white matter, with a surrounding rim of cord that was spared (Fig 4).

The MRI T2 hyperintensity is central, bilateral, more or less symmetrical and multisegmental. 2. MRI T2 central isointensity, or dot (within and in the core of the MRI T2 hyperintensity) might be present and is believed to represent central gray matter squeezed by the uniform, evenly distributed ...

MRI OF THE CERVICAL SPINE

• Preoperative MR imaging and CT myelography are successful in confirming clinical radiculopathy (Class II). • Multilevel T2 hyperintensity, T1 focal hypointensity combined with T2 focal hyperintensity, and spinal cord atrophy each convey a poor prognosis (Class III).
