Specificity of CT myelographic findings in cervical nerve root symptoms
In a series of 62 patients with cervical nerve root symptoms CT myelography of the cervical spine revealed specific radiological signs in 24 patients. These signs are: stenosis of the spinal canal, nerve root swelling and/or soft disc herniation. Disc bulging or spondylotic encroachment with only partial narrowing of the myelographically visible part of the foramen, and often unilateral flattening of the cord is considered clinically insignificant. A normal appearance of cord and nerve roots was seen in 22 patients.
