Abstract:
Objective To study the value of MRI in the diagnosis of spinal metastasis.Methods MR imaging manifestations of spinal metastasis in 85 cases were retrospectively analyzed.46 cases underwent CT and/or X-ray in the 85 cases.Results Totally 388 metastatic vertebra in the 85 cases were detected by MRI.388 vertebras showed hypointensity on T1WI.354 vertebra showed mixed signal intensity and 34 vertebra showed hypointensity on T2WI.All of the vertebra showed hyperintensity on T2WI/STIR.54 vertebra showed pathologic fracture,53 vertebra were protrusion in postetrior,54 vertebra with appendages damage and paravertebral soft tissue mass presented and vertebral canal involved in 30 cases.18 cases were detected with lesion in 46 cases having X-ray and/or CT data,the positive rate was 39.11%(18/46).Conclusion MRI can detect spinal metastatic lesion early,the extent and degree of the tumors can be judged by MRI exactly.
