Abstract Objective: To analyze the types of brachial plexus root avulsion within spinal canal on coronal image of CT-myelography(CTM). Methods: Two hundred and ninety-seven cases with brachial plexus injury underwent 16－slice and 64－slice CT scanning after myelography and coronal, sagittal and oblique axial reconstructive images of CTM were reviewed and correlated with surgical findings as gold standard. Results: The injury of 768 brachial plexus roots within spinal canal was shown on CTM, including 608 cases of complete avulsions, 121 cases of partial avulsions(single anterior or posterior root avulsion in 69, partial anterior or posterior root avulsion in 52) and 39 cases of broken nerve roots. Special signs of partial anterior or posterior root avulsion and the breaking of nerve roots were found on the coronal reconstructive images. Conclusion: It will be more accurate to evaluate the injury types of brachial plexus roots within spinal canal combining the coronal and oblique axial reconstructive images of CTM.
