摘　　要：目的　探讨MRI在诊断钙化性黄韧带肥厚椎管狭窄症中的应用及椎管狭窄分级。方法　本文收集 3 1例钙化性黄韧带肥厚椎管狭窄症的病例 ,经手术及CT扫描证实。结果　本组 3 1例中 ,共计 63个病变 ,分布C3 ～L2 水平 ,2 2个病变分布于C4～ 7椎体水平 ,2 7个病变位于T9～ 12 椎体水平 ,T2 WI显示 5 0个病灶为低信号影 ,13个病灶为低信号区内中等信号影 ,T1WI显示 5 0个病灶为低信号 ,13个病灶为低信号区内高信号影。 2 3例伴随椎间小关节增生硬化 ,18例伴随相应椎间盘突出或退变 ,2 8个病变显示脊髓受压 ,13个病变伴相对应脊髓变性。Objective To sutdy MRI diagnosis and grading of the spinal canal stenosis caused by calcific thickening of ligamentum flavum.Methods MRI findings of 31 cases with the spinal canal stenosis caused by calcific thickening ligamentum flavum(TLF) proved by surgery and/or CT scan were analysed.Results Of 31 cases,63 lesions were found at C 3～L 2 level,22 lesions at C 4～7 level and 27 lesions at T 9～12 level.On T 2WI,50 lesions showed low signal intensity,intermediate signal intensity in 13 lesions.On T 1WI,50 lesions showed low signal intensity,high signal intensity in 13 lesions.Spinal facet arthropathy was showed in 23 cases.18 cases were in company with disc degeneration,cord compression was showed in 28 cases.13 lesions were associated with cord degeneration.Conclusion MRI can directly and noninvasively demonstrate the location of TLF and degree of cord compression.
