It is a prospective, cross-sectional descriptive study. Result: On CT myelography, more dorsal rootlets were found at all levels from C5 to T1 as compared with ventral rootlets and the most rootlets were at the C6 level. On MRI, there were 4 cases of abnormal anatomy of trunk (10%), the angles formed by root and spinal cord gradually increase from C5 to T1. Conclusion: CT myelography, MRI and electrodiagnosis are useful diagnostic imaging methods for brachial plexus lesions.
