颈椎间盘突出症磁共振特点与临床误诊原因的探讨

Exploration MRI feature and the cause of clinical misdiagnosis on cervical disc herniation

目的 探讨颈椎间盘突出症的ＭＲＩ特点与临床误诊的原因。方法 对８２ 例颈椎间盘突出症患者的磁共振表现及临床资料进行分析。结果 颈椎间盘突出症患者大部分与颈椎退行性变密切相关。且多为数个间盘突出，以颈５／６间盘多见，脊髓及神经根受压亦较重。有些患者的临床症状与椎间盘突出的部位不一致而引起误诊。结论 ＭＲＩ是目前诊断颈椎间盘突出症的理想方法。它不仅显示椎间盘突出的范围和程度、对脊髓及神经根受压的情况，还能反映周围其他结构的改变。

Objective To explore MRI feature and the cause of clinical misdiagnosis on cervical disc herniation.Methods MRI manifestation and clinical data of 82 patients with cervical disc herniation were analysed.Results Most patients with cervical disc herniation were related to cervical spine degeneration, and multiple disc herniations were common, the level that was most frequently affected by herniation was C 5～6 . In some cases, The clinical symptom was not correspondence with the level of disc herniation and it often resulted in misdiagnosis. Conclusion MRI was the optimal modality for diagnosis of cervical disc herniation, it did not only show us the size and extent of herniated disc, but also reflected the change of surrounding structure. Key words Cervical disc herniation Magnetic resonance imaging(MRI) Clinical diagnosis.ATP synthetic content( P <0.05). Conclusion The primary changes after 1h and 2h of hypoxic ischemia were mitochondrial swelling and disorganization of cristal membrane respectively.The swelling degree of mitochondria was consistent with that of the perineuclear cytoplasm.The decrease of mitochondrial cristal membrane density of hypoxic ischemic newborn rats was tightly related to dysfunction of mitochondrial respiration and energy synthesis.
