The MRI Performance And Imaging Comparsion Study Of MRI, CT And X-ray In Spinal Tuberculosis

Objective To evaluate the value of MRI in diagnosis of spinal tuberculosis, discusses the X-ray ,CT and MRI feature of spinal tuberculosis , compare the three examine methods ,and improve the level of diagnosis.Materials and Methods The MRI appearance of 32 patients with spinal tuberculosis proveded by clinic or pathology were recorded and analyzed. The MRI changes of vertebral bidies, intervertbral discs, abscess and vertebral canal were compared with that of CT scans and x-ray films of 22 patients who underwent piain X-ray ,CT and MRI in the same time .Result 83 vertebral bidies were destroyed in 32 patients, and 56 intervertebral discs were destroyed in 24 patients, and the intervertebral gap narrowed or vanished . There were 60 cold abscess near the 26 involved vertebral bidies, and it presented the neurocanal to be narrowed in 16 patients. 3 patients had abnormal signal in their spinal cord. Sensitivity of vertebral bidies involved is 100%,and diagnosis accuracy is 96.8% in 32 patients MRI examination compared with the pathological result or the clinical revisit result. 22 patients MRI appearance compared with with that of X-ray and CT in demonstration tuberculosis pathological change's. In judging the vertebral bidies and intervertebral disc destruction , forming of abscess , the narrow degree of vertebral canal, MRI has the great superiority. In judging the forming of the necrotic bone, CT has the great superiority.Conclusion MRI has the high sensitivity in judging pathological changes of spinal tuberculosis ,it causes to the tuberculosis early diagnosis into possible. Conventional radiography and CT have advantage. Many kind of imaging technical supplementary is the key of correct diagnosis.
