Abstract: 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.
