【Abstract】 Objective To investigate the characteristics and diagnostic value of magnetic resonance imaging(MRI) for spinal stenosis with skeletal fluorosis. Methods 6 patients of spinal stenosis with skeletal fluorosis underwent magnetic resonance imaging(MRI) examination on a Philips Gyroscan Intera 1.5T MRI system. The authors analysed the MRI appearances of the patients. Results 6 cases had apparent skeletal fluorosis and spinal stenosis with various degrees. The spinal cord compression included: 2 cases in thoracic vertebra, 3 cases in thoracic and lumbar vertebra, 1 case in lumbar vertebra. 1 case had localized degeneration and necrosis in compressed spinal cord. There were 5 cases with low intensity signals of vertebrae, 3 cases with thickenings of posterior longitudinal ligaments, 5 cases with thickenings of ligamenta flava, 4 cases with thickenings of anterior longitudinal ligaments, 3 cases with enlargements of intervertebral joins, 2 cases with protrusions and 2 case with intumescentia of intervertebral disks. Conclusion MRI can show clearly compression and degeneration of spinal cord and it is very valuable for the diagnosis and evaluation of treatment of spinal stenosis with skeletal fluorosis.更多还原
