颈椎病患者MRIT_2WI髓内有高信号与无高信号的比较研究

A comparative radiological study of cervical spinal cord with and without MRI T_2 weighted image high signal in cervical spondylosis patients

目的 探讨颈椎病患者MRIT2 WI(T2 加权像 )髓内高信号产生的原因及其临床意义。方法 颈椎病患者MRI检查中 ,随机抽取T2 WI髓内高信号和无高信号的各 5 0例 ,对其主诉、症状、体征、MRI的表现进行比较。结果 MRIT2 WI颈脊髓内高信号的患者以老年人居多 ,其主诉、症状和体征多符合脊髓型颈椎病的诊断。结论 MRIT2 WI髓内高信号的产生可能与脊髓前动脉受压有关 ,此类患者临床症状重 ,必须引起高度重视。

Objective To investigate the causes and clinical implication of MRI T 2 weighted image(WI) high signal in cervical spinal cord of cervical spondylosis patients. Methods Fifty cases with and fifty without T 2WI high signal were selected randomly among the cervical spondylosis patients who have received the MRI examination. The chief complaints, symptoms, signs and MRI patterns were compared between these 2 groups of patients. Results Most of the patients with MRI T 2WI high signal in the cervical spinal cord were elder. Their chief complaints, clinical symptoms and signs were highly consistent with the cervical spondylotic myelopathy diagnosis. Conclusion The MRI T 2WI high signal detected in the cervical spinal cord may have relationship with the compression of anterior spinal artery. The clinical symptoms in these patients are usualy more serious, so attentions must be paid to this subset of cases.
