摘　　要：目的探讨MRI诊断黄韧带肥厚(TLF)致脊髓受压损伤及椎管狭窄的意义。方法对84例黄韧带肥厚(TLF)患者的MRI及临床表现进行回顾性分析。椎管狭窄分为4度0度,Ⅰ度(轻度),Ⅱ度(中度),Ⅲ度(重度)。结果脊髓轻度受压26例,中度受压36例,重度受压22例。脊髓受压程度的MRI表现与临床症状和体征有密切关系。椎管重度受压T2WI像脊髓内出现高信号者预后不良,往往伴有椎管狭窄。结论MRI是诊断黄韧带肥厚的主要方法,并对黄韧带肥厚所致的脊髓受压损伤及椎管狭窄的诊断有着十分重要的价值。Objective To determine the value of MRI in the evaluation of spinal cord compression (SCC) and spinal canal stenosis (SCS) due to ligamentum flavum thickening (LFT).Methods MRI findings in 84 patients with LFT were retrospectively analyzed and compared with the clinical manifestations . SCC in the group patients was divided into four degrees .Results MRI most accurately demonstrated mild SCC in 26 cases ,moderate SCC in 36 cases and severe SCC in 22 cases .MRI findings of SCC were close correlated with clinical manifestations ,when spinal cord was hyperintense on T2WI ,it frequently complicated with SCS ,at the same time ,the clinical prognosis would become more poor .Conclusion MRI can provide reliable informations for SCC and SCS induced by LFT and therefore it should be the preferred means of diagnosing LFT.
