摘　　要：目的观察和探讨正常腰骶部脊神经根的解剖和磁共振PROSET序列显示腰骶部神经根的价值。方法采用PROSET技术做冠状面正常腰骶部神经根成像20例,所有原始图像均经3D最大信号强度投影(MIP)后处理。结果20例PROSET成像均清楚显示硬膜囊、硬脊膜鞘外形及脊神经根、神经节和部分节后段的走形,MIP重建图像能多方位观察神经根走形。结论PRO-SET序列对显示腰骶神经根解剖具有独特优势,结合常规磁共振图像,为临床诊治腰骶神经根病变提供满意的影像学依据。Objective To investigate the applied value of MR PROSET in depicting normal lumbosacral nerve roots. Methods PRO-SET was performed with 3D FFE in 20 volunteers. Maximum intensity projection （MIP） was used for every image reconstruction. Results Lumbosacral nerve roots ,ganglions and post -ganglion nerve were well demonstrated in primary images of PROSET as well as dural sac and nerve root sheaths,and could be observed with multi - angle in MIP images. Conclusion MR PROSET is useful in the visualization of nerve roots and the diagnosis of nerve root diseases .
