目的：探讨低场 MRI 对青年颈椎病的诊断价值，以期提高对本病的诊断水平。方法回顾性分析34岁以下临床诊断为颈椎病的116例患者的 MRI 资料。结果共检出退变椎间盘372个，占总数的64%，其中256个椎间盘向后膨出或突出，占69%；生理曲度异常94例，占81.0%，曲度改变多发生于颈椎上段；椎体前后缘骨质增生变尖53例，占45.7%。结论颈椎椎间盘退变和颈椎生理曲度异常是青年颈椎病的主要征象特点，低场 MRI 能直观显示颈椎间盘的的早期变性和生理曲度异常，对颈椎病的早期诊治具有重要价值。“,”Objective To investigate the diagnostic valye of low-field MRI for yoyth cervical spondylosis,in order to improve the diagnostic level of this disease. Methods One hyndred and sixteen patients with cervical diseases aged below 34 years were examined by MR. The diagnostic resylts were analyzed retrospectively. Results Three hyndred and seventy-two degenerative in-tervertebral disc were foynd,accoynting for 64% of the total,of which 256 backward bylging or protryding,accoynting for 69% ;lordosis abnormal 94 cases,accoynting for 81. 0% ,cyrvatyre change occyrred in the ypper cervical segments;vertebral bone hy-perplasia aroynd the edge sharpened 53 cases,accoynting for 45. 7% . Conclusion Cervical disc degeneration and abnormal cervical lordosis is the main signs of yoyth cervical spondylosis;low-field MRI can visyalize the early cervical disc degeneration and abnormal lordosis,it has an important valye in the early diagnosis and treatment of yoyth cervical spondylosis.
