摘　　要：目的:探讨SPACE序列三维快速自旋回波成像技术在正常臂丛神经节后段磁共振成像中的应用价值。方法:对35名无臂丛神经损伤病史的健康志愿者行臂丛神经DWIBS序列、SPACE序列扫描。分析比较DWIBS序列、SPACE序列可清晰显示臂丛神经的数目,以及两组序列图像平均信噪比(SNR)和对比噪声比(CNR)。结果:35名共70侧臂丛神经节后段在冠状DWIBS序列、SPACE序列上均能清晰显示,SPACE序列中部分臂丛内侧束、后束和外侧束也可显示。SPACE序列的图像信噪比和对比噪声比高于DWIBS序列,且差异具有统计学意义。结论:SPACE序列可以清楚地显示臂丛神经节后段,与DWIBS序列相比较对正常臂丛神经显像具有更高的清晰度。Objective： To investigate the value of enhanced 3D SPACE sequence in displaying brachial plexus. Methods：35 healthy volunteers with no history of brachial plexus injury of brachial plexus MRI examinations by DWIBS scan, and SPACE scanned. Analysis and comparison of DWIBS sequences, sequences of SPACE provides a clear display of the brachial plexus, and two sets of image sequence average signal-to-noise ratio （SNR） and the contrast to noise ratio （CNR）. Results：A total of 35 cases 70 lateral brachial plexus after coronary DWIBS is clearly displayed on the sequence;the partial medial cord of brachial plexus, beams and lateral beams can also be displayed in the SPACE sequence. SPACE sequence of image signal-to-noise ratio and contrast noise ratio than the DWIBS sequence, and the difference is statistically significant. Conclusion：SPACE sequence can clearly show the brachial plexus, and DWIBS sequences compared to the normal image has a higher resolution of the brachial plexus.
