摘要
目的探讨MRI弥散加权成像(DWI)在脊柱结核诊断中的价值。方法回顾性分析经临床证实15例脊柱结核的MRI图像表现。应用常规MRI及矢状位DWI(b值分别为150、300、450、650s/mm2)扫描脊柱。结果发现在DWI序列上,b=300s/mm2时对脊柱结核病变真实大小及病理特征显示更佳,同时对弥散像上良、恶性病变进行了鉴别。结论应用常规MRI扫描加上DWI矢状扫描对脊柱结核的诊断及鉴别诊断有一定的指导意义。
Objective To discuss the diagnosis value of diffusion weighted imaging for spondylocace. The MR imaging features of 15 patients with spomtyloeace proved pathologlcally were reviewed retrospectively. Application convention MRI and saglttal DWI （different b,b=150,b=300,b=450,b=650）seanned vertebral column. Results Compared with the other means,the discovei of the spondylocace change on the signal of b=300 in the DWI sequence was able to be clear about the spondylocace change real size. Conolusion The application f conventional MRI and sagittal DWI is very useful for the stages of spondylocace.
