Abstract:
Objective To discuss the characteristic of brachial plexus root avulsion injury of high resolution MR imaging and the value in diagnosing of brachial plexus root avulsion injury early.Methods Fourty-five cases of brachial plexus root avulsion injury patients had being used for investigation to find the characteristic and diagnostic value of MR image of brachial plexus root avulsion injury,which all have pre-operative MR imaging and were diagnosed brachial plexus root avulsion injury by intra-operative exploration and electrophysiology form February 2006 to February 2011.Results Post-traumatic spinalmeningolceles were seen in 42 cases,the frequency was 93.3％; Displacement of spinal cord was seen in 25 cases,the frequency was 55.6％; Absence of anterior and posterior root of spinal nerve was seen in 8 eases,the frequency was 17.8％;Black line sign was seen in 18 cases,the frequency was 40.0％.The sensitivity,specificity,and accuracy of MRI in diagnosing brachial plexus root injury were 95.7％,77.8％ and 94.6％ respectively.Conclusion Posttraumatic spinalmeningolceles are most often seen in MR of brachial plexus root avulsion injury,this sign can play an important role in diagnosing and treatment of brachial plexus root avulsion injury.
