Study Of The Value Of MRI In Differentiating Brucella Spondylitis From Tuberculous Spondylitis

Objective: To evaluate the value of MRI in differentiating brucella spondylitis from tuberculous spondylitis.Methods: A retrospective analysis was performed on 91 cases of brucella spondylitis and 112 cases of tuberculous spondylitis who underwent MRI examination,in January 2015 to December 2017 in the First Affiliated Hospital of Xinjiang Medical University.MRI examinations were performed with T1 WI,T2WI and STIR images.MRI analysis indexes included lesion site,MRI signal,vertebral destruction,wedge change,kyphotic deformity,appendage destruction,dead bone,vertebral hyperplasia,intervertebral space,abscess site and abscess range,and statistical analysis was performed.Results: Brucella spondylitis was more common in lumbar spine and tuberculous spondylitis was more common in thoracic vertebra.In T2 WI,brucella spondylitis group was significantly higher than tuberculous spondylitis group(51.65% vs.24.11%,P<0.05),in STIR,tuberculous spondylitis group was significantly higher than brucella spondylitis group(72.32% vs.59.34%,P<0.05).In vertebral mild destruction,vertebral hyperplasia,normal intervertebral space,paravertebral abscess and abscess within the range of the affected vertebral body,the incidence of brucella spondylitis was significantly higher than that of tuberculous spondylitis(P <0.05).In vertebra evident destruction,vertebra wedge change,kyphotic deformity,dead bone,abnormal intervertebral space,psoas major abscess,abscess beyond the scope of the lesion vertebra signs,the incidence of tuberculous spondylitis was significantly higher than that of brucella spondylitis(P <0.05).Conclusion: Brucellosis spondylitis and tuberculous spondylitis can be distinguished by MRI analysis of bone hyperplasia,vertebral destruction,vertebral wedge change,posterior process deformity,dead bone,intervertebral space,paraspinal abscess and psoas major abscess.
