Ninety-three patients with cervical injuries by traffic accidents, 67 patients with cervical radiculopathy and 56 control adults were examined by MRI. Numbers and levels of affected discs were investigated on a sagittal view, and direction of disc herniations on a transverse view. MRI findings were compared with plain X-ray findings. Much more affected discs were observed by MRI than by X-ray examination, especially in the cases of traffic injury. In most cases, affected levels revealed by MRI were not coincident with those found in X-ray. It was suggested that narrow discs observed in X-ray were already low activity level, so it is not liable to be injured now.A majority of herniated discs were directed toward midline or near midline. It is supposed that these central herniations seldom manifest objective signs and, therefore, that it is difficult to identify the attributable level in the cervical spinal injuries without MRI.
