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.
在一组62例有颈神经根症状的患者中，颈椎CT脊髓造影显示24例患者有特定的放射学征象。这些征象包括：椎管狭窄、神经根肿胀和/或软性椎间盘突出。仅椎间孔脊髓造影可见部分出现椎间盘膨出或骨质增生性压迫且仅有部分狭窄，且脊髓常单侧扁平，临床上认为无明显意义。22例患者脊髓和神经根外观正常。
