摘　　要：目的 :探讨胸椎黄韧带骨化 (OLF)与脊髓改变的MRI诊断意义。方法 :对 2 3例OLF患者的MRI表现 ,临床表现 ,椎管狭窄程度进行回顾性分析。结果 :黄韧带骨化以下胸椎为多 ,伴有不同程度的椎管狭窄。Ⅰ°5例 ,Ⅱ°13例 ,Ⅲ°5例。Ⅲ°狭窄者脊髓内于T2 加权像出现高信号改变其预后不良。结论 :OLF是引起椎管狭窄和脊髓及神经根压迫症状的常见疾病之一 ,T2 WI可准确检出OLF的大小范围以及骨髓受压程度。Objective:To evaluate MRI diagnosis of OLF and the changes of myelopathy in the thoracic spine.Methods:The MRI,clinical manifestations and the degree of spinal cord compession of 23 cases with OLF were reviewed.Results:In most cases,OLF occurs in the lower thoracic spine with spinal cord compression in varying degree,MRI grading of cord compression is:Ⅰ° in 5 cases,Ⅱ° in 13 cases,Ⅲ°in 5 cases,In the cases of severe cord compression,there is high signal intensity in spinal cord of T 2 weighted images,the prognosis was poor.Conclusion:OLF is one of the common causes of compression of the thoracic spinal cord.Sagittal T 2WI is highly reliable in evaluation of OLF and the degree of spinal cord compression.
