Central canal stenosis c3
How is cervical canal stenosis classified?
MATERIALS AND METHODS. Cervical canal stenosis was classified according to the T2-weighted sagittal images into the following grades: grade 0, absence of canal steno- sis; grade 1, subarachnoid space obliteration exceeding 50%; grade 2, spinal cord deformity; and grade 3, spinal cord signal change.
What is central stenosis?
Sometimes this causes partial compression (stenosis) of the nerve tunnel within the spine. This is called central stenosis. Sometimes there is a constriction to the smaller side tunnels with the spine. This is called foraminal stenosis.
What does an MRI show in a spinal canal stenosis?
MRI visualizes not only the width and length of the spinal canal but also depicts in detail the spinal cord, intervertebral disks, osteo- phytes, and ligaments, all of which are po- tential causes of spinal canal stenosis .
What level is spinal canal stenosis at?
Spinal canal is significantly narrow at C5–6 level, and signal intensity of spinal cord is increased at corresponding level. Fig. 4—61-year-old woman with cervical canal stenosis. Sagittal T2-weighted fast spin-echo image shows grade 2 stenosis at C4–5 level (arrow).

Cervical stenosis. Cervical stenosis is the narrow-ing of the neuroforaminal, lateral recesses, or central canal. It is classifi ed as either degenerative relating to disk degeneration, facet hypertrophy, kyphosis, or ligamentum fl avum hypertrophy; or congenital, which is associated with an altered spinal canal develop-

fers to the absence of central canal stenosis (Fig. 2). Grade 1 refers to nearly complete obliteration of subarachnoid space, including obliteration of the arbitrary subarachnoid space exceeding 50%, without signs of cord deformity (Fig. 3). Grade 2 refers to central canal stenosis with cord deformi-ty but without spinal cord signal change (Fig ...

Spinal Stenosis Spinal stenosis is a term used to describe a narrowing of the spinal canal. The narrowing may not cause any symptoms. However, the narrowing may progress to cause squeezing (compression) of the spinal nerves . Spinal stenosis can cause back pain and/or leg pain. Most often it occurs when you walk. Weakness of the legs may make you
