[Abstract] Objective: To explore the value of dynamic contrast enhanced (DCE) MRI in differential diagnosis of brucellosis spondylitis.Materials and Methods: Sixteen cases with spinal lesions(proved by clinically or histologically: 11 cases were brucellosis spondylitis, 2 cases were vertebral metastases, 3 cases were tuberculous spondylitis) received T1WI, T2WI, STIR and DCE-MRI examination. Morphological and MRI features were analyzed.Results: The lesions were mainly located in the lumbar vertebrae. In the MRI of brucellosis spondylitis, morphology of vertebral body was almost normal. Bone destruction and osteophyte were detected in the rim of vertebral body. The affected vertebral body showed hypointense on T1WI, hypointense, isointense, hyperintense or heterogeneous intense on T2WI and hyperintense on STIR. After injection of contrast media, signal of affected vertebral body was similar to or higher than that of adjacent vertebral body. There were significant differences between the different spinal lesions for Ktrans values and Ve values (P<0.05).Conclusion: Brucellosis spondylitism has some MRI characteristics. DCE-MRI has significant value in the differential diagnosis of brucellosis spondylitis.
