PDFAbstract
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.
