摘　　要：目的评价MR弥散技术对脊柱单纯性和病理性压缩性骨折的诊断价值。方法研究国内外应用弥散序列检查鉴别脊柱椎体压缩性骨折良恶性的进展,包括病理性骨折;外伤或骨质疏松所致椎体压缩性骨折。结果单纯性压缩性骨折在DWI表现为等低信号混有条状高信号,病理性椎体压缩性骨折DWI上表现为高信号及等低信号。结论MRI弥散序列的信号改变能鉴别脊柱单纯性压缩性骨折和病理性骨折,但需进一步定量研究。Objective：To evaluate the effectiveness imaging （DWI） for differentiating between benign and study the progression of vertebral fracture patients in of qualitative diffusion weighted magnetic resonance pathologic vertebral compression fracture.Methods：To internal and overseas in,including pathologic,traumatic and osteoporotic fracture, were examined with Diffusion weighted MR imaging. Results：Benign fracture and pathological fracture all revealed iso or hypointense mixed with band hyperintensity on DWI.Pathological Fracture were hyperintense signal intensity on DWI.Conclusion：Qualitative diffusion weighted MR imaging can distinguish pathologic and benign vertebral compression fracture.Further quantitative diffusion weighted MR study may be needed.
