Abstract
BACKGROUND:MRI was extensively used in spinal trauma, but morphological parameters of MRI on thoracolumbar segments of normal persons were not established in China. <br> OBJECTIVE: To measure wedging index of thoracolumbar vertebra in healthy population using MRI, and to proved MRI morphology data for differentialy diagnosing thoracolumbar vertebra fracture and wedging of normal persons. <br> METHODS: 120 healthy volunteers aged 20-50 years old were recruited from November 2011 to August 2013. Al volunteers underwent 1.5T MRI scan for thoracolumbar vertebra. Heights of leading and trailing edges of T11-L2 vertebrae were measured using sagittal fast spin-echo T2WI and wedging index was calculated. <br> RESULTS AND CONCLUSION:Wedging indexes of T11-L2 vertebrae were respectively 0.91±0.05, 0.91±0.05, 0.88±0.08 and 0.91±0.08. Numbers of wedging of T11-L2 vertebrae were respectively 103 (23.52%), 112 (25.57%), 115 (26.26%) and 108 (24.66%). No significant difference in wedging indexes was detected among groups, but wedging index was smal in older volunteers. Wedging indexes were smaler in males than females. Wedging indexes of T11 and L2 were smaler in heavy manual workers than in non-heavy manual workers. Wedging indexes were associated with height and body mass index. Results indicated that wedging changes to different degrees existed in thoracolumbar vertebrae of normal persons, and the degree of wedging was correlated with many factors.关键词
