24 patients with cervical disc herniation were treated operatively and examined using superconducting 1.5 Tesla magnetic resonance imaging before and after their operations. 10 (41.7%) of the 24 cases showed lesions of a high intensity area (H. I. A.) in the spinal cord on the sagittal Fast scan images before surgery.
We could not confirm whether there being a H. I. A. or not, related with the factors of age, the duration of symptoms, the JOA score prior to operation, and the rate of improvement.
In 4 cases there remained slight lesions of the H. I. A. 1 case was stationary, and in 5 cases the symptoms had disappeared. The last group's results were better than the other two.
