Clinical value of CR,CT and MRI in spinal tuberculosis / 中国矫形外科杂志

ABSTRACT

[Objective]To investigate the clinical value of computed radiography(CR),computed tomography(CT)and magnetic resonance imaging(MRI)in spinal tuberculosis.[Method]Forty-one patients with histologically confirmed spinal tuberculosis underwant imaging examinations.Forty-one patients were performed CR,22 CT and 31 MRI.[Result]CR of 38 patients clearly revealed bone changes and narrowed or disappeared disk space.CR of 30 patients well showed the abnormal soft tissue.CT scan of 22 patients clearly depicted calcification and no abnormal was found in pedicles in all the 22 CT scans.CT scan of 21 patients revealed bone changes of vertebral bodies and CT scan of 20 patients showed abnormal soft tissue.The soft tissue was involved in all 31 patients with spinal tuberculosis.Diskspaces were involved in 29 cases and the pedicles were normal in all 31 case.The lesions showed hypointense in T1 scan primarily,hyperintense in T2 scan primarily.[Conclusion]CR is the first imaging approach for spinal tuberculosis.CT well reveal the extent and minute calcification.The extent,abnormal soft-tissue and abnormal disk space are more dramatically demonstrated on MRI imaging.CR,in addition to CT and MRI,is helpful in diagnosis of spinaltubereuinsis.
