摘要目的探讨磁共振扩散加权序列成像对良、恶性椎体压缩性骨折鉴别诊断的价值。方法对36例48个骨折椎体常规平扫后行扩散加权成像,良性组21例30个骨折椎体,恶性组15例18个骨折椎体。测量病变椎体的信号强度比和信噪比。结果磁共振扩散加权序列成像结果显示,与邻近正常椎体相比,良性骨折椎体呈低或等信号,恶性骨折椎体呈高信号。良性组信号强度比为0.19±0.38,信噪比为1.39±0.47;恶性组信号强度比为3.84±2.59,信噪比为3.96±2.05。良性组、恶性组患者的骨折椎体的信号强度比、信噪比差异显著(P<0.01)。结论磁共振扩散加权成像在良、恶性椎体压缩性骨折鉴别诊断中应用价值高,能够为临床治疗提供有价值的参考资料。
