[Abstract] Objective: To explore MRI characteristics and diagnostic value of spinal tuberculosis.Material and Methods: Sixty-seven cases of patients previously diagnosed with spinal tuberculosis in our hospital were selected as TB group, 40 patients who have spinal disease with non-tuberculous were selected as control group, the X-ray, CT, MRI imaging data of the two groups were analyzed respectively to explore the MRI characteristics and diagnostic value of spinal tuberculosis.Results: Sixty-seven patients involved a total of 162 vertebrae, among which 30 patients involved with lumbar spine cases (44.77%), involving 80 lumbar vertebrae (49.38%), among the 162 vertebral body involvement, MRI showed bone destruction in 62 cases (92.54%), abscess formation in 57 cases (85.07%), endplate damage in 52 cases (77.61%). The detection rate of MRI in bone destruction, disc involvement is 100%. In bone destruction, endplate damage, disc involvement, abscess formation, spinal involvement and sequestration, the detection rate of MRI is significantly higher than the X-ray, CT (P <0.05), MRI detection rate of calcification is lower than CT detection rate (P<0.05). The sensitivity of MRI in diagnosing spinal tuberculosis is 92.54%, the specificity is 87.50%. The sensitivity of CT in diagnosing spinal tuberculosis is 68.66%, the specificity is 82.50%. The sensitivity of X-ray in diagnosing spinal tuberculosis is 47.76% and the specificity is 70.00%.Conclusions: The detection rate of MRI in diagnosing the early characteristics of spinal tuberculosis is higher, which is significantly better than X-ray and CT in diagnosing patients with spinal tuberculosis.
