Sixty-four dogs with histories and clinical signs consistent with cervical intervertebral disk disease were presented for evaluation. Survey spinal radiographs were obtained, followed by myelography. In 61% of the survey radiographs, evaluators identified sites of disk extrusion or protrusion based on radiographic findings. Of those radiographs where a site was identified, ability to accurately identify the correct site of disk extrusion ranged from 53% to 67%, with an average of 58%. Therefore, the overall accuracy rate for correct identification of the site(s) of disk extrusion for all survey radiographs was 35%. Twelve cases had more than one site of disk extrusion or protrusion evident myelographically. In cases where multiple sites of extrusion were confirmed myelographically, the ability to localize at least one of the sites on the corresponding survey radiographs ranged from 63% to 80%, with an average of 70%. The major site of disk extrusion or protrusion was incorrectly identified in 16% to 31% of the survey radiographs, with an average of 26%. The use of survey radiographs alone is an inaccurate means for localization of cervical intervertebral disk extrusion or protrusion.
