为探讨低场强磁共振成像（Magnetic resonance imaging ，MRI）对兔椎体骨折及其愈合程度的评判价值，选取年龄、体重均相近的健康成年雌性新西兰大白兔21只，手术造成椎体骨折后，分别在骨折后的24 h、72 h、1周、2周、4周、6周、8周观察其愈合的M RI表现，并与其病理学改变对照分析。结果发现，随着骨折的修复，骨折椎体逐渐由长T1、长T2信号恢复为等T1等、T2信号。表明M RI的信号改变在一定程度上能反映兔椎体骨折愈合过程中的病理学改变。

To evaluate the value of low field magnetic resonance imaging (MRI) in the diagnosis of healing process of vertebral fracture ,twenty-one healthy adult female rabbits with the same age and weight were selected ,firstly ,the animal models of vertebral fracture were made by operation ,then they were examined with MRI at 24 hours ,72 hours ,1 week ,2 weeks ,4 weeks ,6 weeks ,8 weeks ,respectively .MRI mani-festations were analyzed with the pathological changes .The results found that with the repairing of the fractured vertebra ,the low signal intensity on T1WI and high signal intensity on T2WI resumed isointesity on T1WI and T2WI .The signal intensity of MRI could reflect the pathology of vertebral fracture of rabbit to some extent .
