【摘要】：[目的]探讨膝关节周围神经MSCT、MRI表现及解剖学特点。[方法]观察37例正常成年人膝关节周围神经在MSCT及磁共振图像上的表现,并对CT图像及磁共振3D-BRAVO T1WI图像在GE公司AW4.6工作站上进行多平面重组,取膝关节周围神经其同层显示层面,观察其影像学解剖特点。[结果]膝关节周围神经影像表现为索条样结构,内含脂肪组织。在MSCT图像与MRI测量并对比胫神经不同水平层面轴截面面积,二者无显著性差异。对照观察多平面重组图像与常规图像,测量胫神经与腓总神经单支显示最大长度、二者走行夹角及同层时神经长度,二者有显著性差异。主要神经走行方向、形态、粗细、张力及毗邻关系通过多平面重组同层能清晰显示。[结论]膝关节周围神经在MSCT与磁共振成像表现基本一致,其解剖特征能利用多平面重建同层理想地显示,3DBRAVO T1WI序列可以应用于外周神经的显示,为膝关节周围神经相关病变的影像学诊断奠定基础。
[Abstract]:[objective] to investigate the MRI features and anatomical features of peripheral knee nerve on MSCT and MRI images in 37 normal adults. The CT and 3D-BRAVO T1WI images were reconstructed on AW4.6 workstation of GE Company, and the peripheral nerves of knee joint were displayed on the same layer. [results] the peripheral nerve of the knee was shown as a chord-like structure with adipose tissue. The axial cross-sectional area of the tibial nerve was measured and compared with that of MRI in MSCT images. The maximum length of tibial nerve and common peroneal nerve was measured. There was significant difference between them. The direction, shape, thickness, tension and adjacent relationship of the main nerves could be clearly displayed by multiplanar recombination of the same layer. [conclusion] the appearance of the peripheral nerve of knee joint on MSCT is basically consistent with that of magnetic resonance imaging. The anatomical features can be used in the display of peripheral nerves by using multiplanar reconstruction of the same layer and ideal display of the 3D DBRAVO T1WI sequence, which lays a foundation for the imaging diagnosis of peripheral neuropathy of the knee joint.
