摘　　要：目的 探讨3D多回波聚合梯度回波序列(3D GEMEC)在腰骶丛神经成像中的应用价值。方法 回顾性分析2022年8~9月六安市人民医院以腰腿疼为主诉的32例住院患者的影像学资料,男15例,女17例,年龄28~78(60.1±15.8)岁。在不同1.5T平台上分别完成腰骶丛3D GEMEC序列和三维T2加权快速梯度回波(3D T2 FFE)序列,比较两种序列腰骶丛神经的信噪比、对比噪声比和主观显示效果。结果 3D GEMEC序列腰骶丛神经的信噪比、对比噪声比以及主观显示效果与3D T2 FFE序列的差异均无统计学意义(P=0.250、0.146、0.083)。结论 3D GEMEC序列可以清晰地显示腰骶丛神经的解剖结构并抑制背景信号,在腰骶丛神经病变的诊断方面具有一定的临床应用前景。Objective To investigate the application value of 3D gradient echo with multi-echo combination(3D GEMEC)sequence in lumbosacral plexus imaging.Methods The imaging data of 32 inpatients who were admitted to Lu'an People's Hospital due to low back and leg pain from August to September 2022 were analyzed retrospectively,including 15 males and 17 females,with age ranging from 28 to 78(60.1±15.8)years old.Lumbosacral plexus 3D GEMEC sequence and 3D T2 fast field echo(3D T2 FFE)sequence were performed on different 1.5T platforms,respectively.Signal-to-noise ratios,contrast-to-noise ratios and subjective display effects of lumbosacral plexus were compared between the two kinds of sequences.Results There was no statistically significant difference in signal-to-noise ratio,contrast-to-noise ratio and subjective display effect of lumbosacral plexus between 3D GEMEC sequence and 3D T2 FFE sequence(P=0.250,0.146,0.083).Conclusion 3D GEMEC sequence can clearly demonstrate the anatomical structure of lumbosacral plexus and suppress background signals.It has prospects in the diagnosis of lumbosacral plexus neuropathy.
