[Abstract] Objective: To explore the diagnostic value of CT and MRI in spinal tuberculosis.Materials and Methods: One hundred and ten cases with spinal tuberculosis confirmed by the surgical operation pathology, needle biopsy and follow-up received Computed Tomography and MRI plain scan, at the same time, some cases received enhance scan.Results: One hundred and ten cases of spinal tuberculosis (TB), including 9 cases of cervical vertebra, 25 cases of thoracic vertebra, 42 cases of lumbar vertebra, 31 cases of thoracic lumbar vertebra and 3 cases of the sacral vertebra. The CT features of spinal tuberculosis are the bone destruction of vertebral body and accessories, the formation of vertebral abscess, sequestrum, calcification and spinal canal stenosis, etc. The MRI features of spinal tuberculosis are MRI of spinal tuberculosis are the bone destruction of vertebral body and accessories, the destruction of intervertebral disc, the formation of vertebral abscess, the invasion of dural and myeloid, the diffusion of sub-ligament, etc. The CT in diagnosing sequestrum and calcification was significantly higher than MRI(P=0.00), but the MRI in diagnosing the bone marrow edema, the invasion of dural and myeloid, the diffusion of sub-ligament was significantly higher than CT(P=0.00).Conclusion: The features of Spinal tuberculosis are diversified, CT and MRI has high value in diagnosis of spinal tuberculosis, CT has the advantage in showing sequestrum and calcification and MRI has the advantage in showing the early stages of dieases, the invasion of dural and myeloid, the diffusion of sub-ligament, such as a combination is helpful to diagnosing and differential diagnosing of spinal tuberculosis.
