Abstract：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.
