Abstract

Objective: To investigate the image findings of branchial plexus injuries on CT myelography, MRI and electrodiagnosis. Subject and method: The study was performed on 40 patients with trauma history and clinically suspected brachial plexus lesions, which were then diagnosed by CT myelography and MRI at the Department of Diagnostic Imaging, 108 Military Central Hospital, electrically diagnosed at Department of Functional Explorations, Hanoi Medical University Hospital and operated at Institute of Trauma and Orthopedics, 108 Military Central Hospital during nearly 2 years, from May 2015 to February 2017. It is a prospective, cross-sectional descriptive study. Result: CT myelography can diagnose complete and partial root avulsions with 5 levels according to Nagano classification. MRI can detect some types of damage such as root avulsion, rupture, edema of the roots and trunks, electrodiagnosis can detect preganglionic and postganglionic damage, complete or partial root lesions. Conclusion: CT myelography, MRI and electrodiagnosis are useful diagnostic imaging methods for brachial plexus lesions.
