Abstract
|
|
|
Magnetic resonance(MR) images of the cervical spine show anatomic detail and pathologic changes unlike any other imging modality.
The authors reviewed MR images of 140 patients referred for cervical spondylosis.
Fatty marrow changes were identified in 582 cervical spines(69%). The changes were independent of age and sex distribution and other degenerative changes.
Disc herniations referring to extrusion of disc material beyond the posterior vertebral line were identified in 216 levels.
Cord compressions referring to a concave defect in the spinal cord adjacent to a site of lesion were identified on T1 weighted image in 152 levels.
Cord signal changes referring to a high signal intensity within the spinal cord on T2 weighted image were observed in 27 patients 51 levels.
MR images can provide sharply defined anatomic delineation and tissue characterization of the cervical spine, and then evidence of degenerative change of cervical spine and secondary effect of cervical disc herniation may be regarded.
