颈椎间盘突出的MRI测量及MRI临床应用价值

MRI measurement of cervical disc herniation and its clinical evaluation

目的 探讨颈椎间盘突出的 MRI测量指标的科学性和临床应用价值。方法 采用椎间盘突出的二个测量指数——矢状径和横径指数 (STI)、矢径指数 (SI)并对矢状 T2 WI图像脊髓信号异常及信号正常的 6 0例颈椎间盘突出进行了测量和分析。结果 颈椎间盘突出测量矢状 T2 WI脊髓信号异常及信号正常的 STI均数之间有明显的差异 (P <0 .0 1) ,SI均数之间有非常显著性差异 ,(P <0 .0 0 1)。结论 把矢状 T2 WI脊髓情况与 STI、SI测量相结合 ,STI与 SI指标作为衡量颈椎间盘突出程度及脊髓有无受压损伤的量化指标客观可靠 ,SI更简化更实用。可作为 MRI间接评估颈椎间盘突出脊髓受压损伤的方法 ,并可指导临床治疗和评估预后。

Objective To evaluate the measurement for cervical disc herniation using MRI and clinical application.Methods 60 cases with abnormal or normal signs of spinal cord on MRI T 2-weighted were analysed by the sagittal and transversal index (STI) and the sagittal index (SI) as the quantitative indicator on MRI scans for measurement of hernia size,including 30 cases with abnormal and normal signs of spinal cord on MRI T 2-weighted.Results Two indexes were correlated significantly to the different signs of spinal cord on MRI T 2-weighte.Conclusion STI and SI used as the quantitative indicator for meseuring cervical disc herniation are objective and reliable.SI is more simple and more practical than STI.In providing formation for treatment and assessment of prognosis.
