摘　　要：目的探讨工业性氟骨症脊柱CT的影像表现及与X线表现的差异。方法选取确诊为工业氟病的30名患者的53个脊柱段的CT表现进行分析,并与常规X线照片表现进行比较。结果 (1)工业氟骨症以骨质硬化为主,也有疏松与软化,韧带钙化/骨化为特征之一,椎管狭窄由黄韧带及后纵韧带钙化/骨化所致;(2)工业氟骨病脊柱CT征象较常规X线照片明显,以骨质硬化为主,且符合中轴骨重于四肢骨的规律,严重程度与X线分期不完全一致。结论氟骨症脊柱CT表现具有一定特点,可作为工业氟骨症X线分期的重要补充。Objective To explore the CT findings of industrial skeletal fluorosis in the spine and its difference with X-ray. Methods CT findings of 53 spinal segments in 30 patients diagnosed as industrial fluorosis were analyzed, and the performances were compared with X-ray images. Results（1） The image findings of Industrial skeletal fluorosis are mainly bone sclerosis, also including osteoporosis and softening. Ligament calcification or ossification is one of the characteristics. Yellow ligament and the posterior longitudinal ligament calcification/ossification leaded to spinal canal stenosis.（2） The signs of spinal CT in industrial fluorosis are more obvious than X-ray photos, with obvious bone sclerosis, and comply with the principle that the severity of axial skeleton is over limbs bone, and its severity degree is not completely consistent with X-ray stage. Conclusion The spinal CT performances of industrial skeletal fluorosis have certain characteristics and it＇s an important supplement for X-ray stage.
