摘要/Abstract

摘要： 目的　探讨3D-T2W-FFE、3D-STIR-TSE、DWIBS三种序列腰骶丛神经显示、影像解剖和3D重建效果。方法　收集49名志愿者常规腰椎磁共振和腰骶丛神经成像数据，其中3D-T2W-FFE 序列48例、3D-STIR-TSE序列47例、DWIBS 序列43例。计算三种序列神经根和骨骼肌的对比度噪声比（CNRN/M）、右侧骶1神经根直径及神经节体积；分别采用各自4等级评分比较这三种序列对腰骶丛神经的显示效果和3D重建效果。结果　三种序列的CNR N/M不全相同，其中3D-T2W-FFE序列与3D-STIR-TSE、DWIBS序列均有统计学差异，P<0.05。三种序列的神经节体积无统计学差异（P=0.050）。三种序列的神经根直径不全相同，其中3D-STIR-TSE序列与DWIBS序列间有统计学差异（P<0.05）。三种序列神经显示评分不全相同，其中DWIBS序列与3D-T2W-FFE、3D-STIR-TSE序列均有统计学差异（P<0.05）。三种序列神经3D重建评分无统计学差异（P=0.025）。结论 3D-T2W-FFE 序列和3D-STIR-TSE FFE序列神经显示和影像解剖评分无差别，较DWIBS序列好。三种序列神经3D重建评分无差别，其中DWIBS序列重建过程最易实现。

Abstract: Objective　To investigate the effect of 3D reconstruction, lumbosacral plexus's display and image anatomical measurement of 3D-T2W-FFE, 3D-STIR-TSE and DWIBS sequences.　Methods 　Data of 49 volunteers underwent conventional lumbar spine MRI and lumbosacral plexus neurography, including 48 cases of 3D-T2W-FFE, 47 cases of 3D-STIR-TSE and 43 cases of DWIBS sequence were collected. The contrast to noise ratio of nerve root and muscle (CNR N/M), the nerve root diameter and ganglion volume of the right sacral of the three sequences were calculated. The lumbosacral plexus's display effect and 3D reconstruction effect were evaluated and compared by different grade 4 scores respectively.　Results　The CNR N/M of the three sequences were not identical, there were statistical differences among the 3D-T2W-FFE sequence, the 3D-STIR-TSE and DWIBS sequences (P<0.05), there was no significant difference in ganglion volume among the three sequences (P=0.050). The nerve roots diameter of the three sequences were not identical, there were statistical differences between the 3D-STIR-TSE sequence and the DWIBS sequence(P<0.05). There was no statistical difference in neural 3D reconstruction score of the three sequences (P=0.025).　Conclusions　There is no statistical difference in the neural display and imaging anatomical score of 3D-T2W-FFE sequence and 3D-STIR-TSE sequence, which is better than DWIBS sequence. There is no statistical difference in the neural 3D reconstruction score of the three sequences, which the DWIBS sequence is easiest to achieve during reconstruction.
