ABSTRACT
Objective To analyze the MRI features of Hirayama disease(HD)with cervical natural position and its diagnostic val-ue.Methods The natural position of cervical vertebra with MRI examination was used in 1 5 patients and 40 normal people.The spe-cificity and sensitivity of MRI features were analyzed and the ratio of cervical sagittal diameter/cervical transverse diameter (CSD/CTD)of the lower cervical cord was measured.Results CSD/CTD of the patients and control group had a significant difference (t=7.99,P =0.00).The sensitivity of LOA was 86.7%,and its specificity was 88.4%.The sensitivity of atrophy of the lower cervical cord was 80.0%,and its specificity was 79.5%.The sensitivity of the cervical spine curvature abnormalities was 40.0%,and its spe-cificity was 65.2%.The sensitivity of abnormal signal in the spinal cord was 46.7%,and its specificity was 87.5%.The sensitivity of abnormal signal in the epidural outer cavity was 20.0%,and its specificity was 96.8%.Conclusion MRI features of lower cervical cord in combination with clinical symptoms and signs can be helpful for the accurate diagnosis of HD.
