剪切波弹性成像在颈椎病患者脊髓功能障碍评估中的价值
Value of shear wave elastography for evaluating the spinal cord dysfunction in patients with cervical spondylotic myelopathy
摘要
Abstract
Objective To evaluate the feasibility and diagnostic value of shear wave elastography (SWE)in assessing spinal cord dysfunction in patients with cervical spondylotic myelopathy. Methods Twenty-six patients with myelopathy were included in our study,the cord compression rate was evaluated by preoperation MRI,and Japanese Orthropeadic As-socition (JOA)scores were also evaluated. All patients were treated by cervical laminoplasty,the elastic modulus of nor-mal segment and the compressed segment spinal cord were measured by Supersonic Imagine AixPlorer real-time SWE,and the decline ratio of the elastic modulus was also calculated;the relationships between the age,duration of disease,cord compression rate,JOA scores and the decline ratio of elastic modulus were analyzed. Results The elastic modulus of com-pressive segment was significantly lower than those of normal spinal cord (P < 0. 01). The decline ratio of elastic modulus was 42. 4％ ± 23. 5％ . There was no significant correlation between the age,duration of disease,cord flattening rate and the decline ratio of elastic modulus (r = 0. 147,0. 268,0. 262,all P > 0. 05). There was a significant negative correlation between JOA scores and the decline ratio of elastic modulus (r = - 0. 426,P = 0. 03). The ICC of the normal segment e-lastic modulus was 0. 959 (95％ CI:0. 912 - 0. 982),and the ICC of the compressed segment elastic modulus was 0. 832 (95％ CI:0. 660 - 0. 921). Conclusions SWE could distinguish the normal and compressed spinal cord and the decline ratio of elastic modulus could reflect the spinal cord dysfunction.关键词
