成人氟骨症的脊柱MRI表现初探

目的：阐述成年氟骨症患者的脊柱ＭＲＩ表现，探讨ＭＲＩ在氟骨症中的诊断价值。方法：收集５例成年中度氟骨症患者，使用０．５Ｔ超导磁共振机行矢状ＳＥ序列Ｔ１ＷＩ和ＦＳＥ序列Ｔ２ＷＩ及横断ＦＥ序列扫描。结果：３例表现为椎体信号减低，４例可见黄韧带增厚或骨化，４例可见椎间盘膨出或突出，２例可见前纵韧带增厚，４例可见脊髓受压。

Initial Approach of Spinal MRI Findings in Adult Patients with Skeletal Fluorosis

Purpose:To study the spinal MRI findings of adult patients with skeletal fluorosis,and approach the diagnostic velue of MRI in fluorosis .methods:The authors collected five adult patients with skeletal fluorosis.All MR imagings were obtained by a 0.5T Picker superconducting system.Sagittal T1WI of SE sequence and T2WI of FSE sequence and transversal FE sequence imagings were obtained. Result:Low intensity signal of vertebrae have been seen in 3patients.Thickening of ligmentum flavum have been found in 4 patients. Enlargment or protrusion of intervertebral discs have beeen found in 4 patients.Enlargment of anterior longitudinal ligament have been seen in 2 patients.And spine cord were compressed in four patients.Conclusion:MR imagings of skeletal fluorosis may appear signal changes of vertebral body,thickening of ligment,etc. These findings have diagnostic velue of skeletal fluorosis.The condition of compression in spine cord may supply the foundation of surgical therapy.
