In 42 cases with cervical myelopathy, MRI studies of the A-P diameter of the cervical cord and high intensity area in the cord were performed. They were 19 cases of cervical spondylotic myelopathy (male 14, female 5, age 50-81), 16 cases of OPLL (male 11, female 5, age 40-72) and 7 cases of cervical disk herniation (male 11, female 5, age 20-70). To compare with them, 20 cases without myelopathy (male 10, female 10, age 20-74) were examined by MRI.Results were as follows:1. There was a significant difference in the narrowest diamater between myelopathy group and non-myelopathy group.2. Severe cases in clinical findings had often narrow diamater of spinal cord.3. Postoperatively, some cases who had poor enlargement of the spinal cord had tendency to little improvement of the clinical symptoms.4. High intensity area in MRI did not relate to the improvement of the clinical findings.
