| 目的 评价磁共振选择性水激励脂肪抑制技术(MR-PROSET)在显示腰骶神经(节)中的价值。方法 采用3D PROSET序列扫描健康受试者30例,所得原始图像行3D MIP后处理,结合原始图像及MIP图像观察腰骶神经根(节)的形态和走行,并测量相关解剖数据。结果 PROSET序列图像能清晰显示L1~S1水平的神经根鞘、神经节以及L3~S1水平的节外段神经;L1~2水平的节外段显示稍差。L1~L5水平的神经根鞘长度逐渐增加,而S1水平的神经根鞘长度较L5水平稍短。L1~S1水平的神经根鞘直径、神经节长径、宽径以及面积均自上而下逐渐增加;神经根鞘倾斜角则自上而下逐渐减小。结论 MR-PROSET序列能清晰显示腰骶神经根(节)的解剖形态。 |

| Objective To study the value of MR-PROSET in the demonstration of the lumbosacral nerve roots and dorsal root ganlias (DRGs). Methods PROSET sequence and 3D maximum intensity projection (3D MIP) post-processed were performed in 30 healthy volunteers without low back pain. The L1－S1 lumbosacral nerve roots and DRGs were observed in the raw pictures and 3D MIP pictures. The related values were measured in the 3D MIP pictures. Results L1－S1 nerve root sleeves, DRGs and L3－S1 segments of the nerves posterior to the ganglions were demonstrated well, while L1－L2 segments of the nerves posterior to the ganglions were not demonstrated excellently. The length of the nerve roots increased progressively to a maximum at L5, and decreased at S1. The diameter of the nerve roots, length, midpoint width and area of the DRGs gradually increased from L1－S1, whereas the nerve root sleeve angulation decreased progressively. Conclusion MR-PROSET sequence can display the lumbosacral nerve roots and DRGs clearly. |
