布氏杆菌脊柱炎MSCT和MRI应用价值比较

Objective To investigate the value of Multi-slice spiral CT and magnetic resonance (MR) imaging in Brucellaspondylitis. Methods The imaging findings of 36 patients with brucellosis spondylitis retrospectively analyzed. The patientswere performed 64 layer 128 slice spiral CT and MRI. Results In MRI, 29 had 2 lumbar, 5 had 3 lumbar and 2 had four lumbarvertebrae involvement. Three had the first lumbar, 6 had the second lumbar, 15 had the third lumbar, 24 had the fourthlumbar, 18 had the fifth lumbar and 3 had the first sacral vertebra involvement. Thirty patients had different degreesintervertebral disc involvement. There were 21 patients had the positive findings of intervertebral space narrowing, however,15 patients had no obvious narrowing. Twenty-seven patients had different levels of paraspinal soft tissue swelling. In CT, 27had two lumbar and 4 had three lumbar vertebrae involvement. Additionally vertebral destruction was detected in 63vertebrae. There were 6 cases had no obvious vertebral destructions and 9 cases had no significant vertebral soft tissueswelling. Compared with CT, MRI is a highly sensitive imaging technique in showing the vertebral marrow edema and softtissue involvement, but lack in the ability of showing tiny vertebral destruction. Conclusion The combination of MSCT andMRI can improve the diagnosis of Brucella spondylitis, especially in the involvement degrees and scope.
