【摘要】 目的：分析氟骨症所致椎管狭窄病人的ＣＴ表现特点。方法：１９例均来自高氟区（水氟含量为７～１３ｐｐｍ ），其中男６ 例，女１３例。使用全身ＣＴ机对胸椎、腰椎进行扫描，２例行ＣＴＭ 扫描。结果：１９例均经ＣＴ扫描确诊为黄韧带骨化所致椎管狭窄，而且均为多椎间发生，典型ＣＴ表现为椎管内背侧不同程度的骨样密度区，其厚度为０．６～１．２ ｃｍ ，平均为０．９ ｃｍ 。１８例伴有椎间小关节增生硬化，手术病理证实有黄韧带骨化，其中２例做了骨化黄韧带含氟量测定超过正常２０ 倍以上。结论：ＣＴ扫描是诊断氟骨症所致椎管狭窄的最佳检查方法。更多还原

【Abstract】 Objective:To analyse CT findings of 19 cases with stenosis of spinal canal cause by fluorosis.Methods:19 patients all came from the ares of high fluorine concentration in water(7～13ppm).The patients ranged in age from 38～76 years,6 were men and 13 were women.Thoracic and lumbar spine imaged with plain CT,and two cases with CTM.Results:CT scans demonstrated ossification of the ligamentum flavum(OLF)in all cases,Which caused stenosis of the spianl canal and most of them happend in multiple vertebral space,typical CT findings of OLF were recognized as varied osteoid intensity area(the thickness was 0.6～1.2 cm,mean 0.9 cm) at the posterior margin of spinal canal.Eighteen patients had hypertrophic change of the facet joint and confirmed histopatholgically ossification of the ligamentum flavum.The measurment of fluorine in two cases was done,and the value was over normal 20 times.Conclusion:CT scan is the best methed for diagnosis of stenosis of spinal canal caused by fluorosis.更多还原
