Three-tesla magnetic resonance neurography of the brachial plexus in cervical radiculopathy

ABSTRACT Introduction: There have been no reports of the use of 3‐Tesla magnetic resonance neurography (3T MRN) to characterize cervical radiculopathy. In particular, there are no reports of MRN of brachial plexus involvement in patients with cervical radiculopathy. Methods: We reviewed retrospectiv...

Description
Summary:ABSTRACT Introduction: There have been no reports of the use of 3‐Tesla magnetic resonance neurography (3T MRN) to characterize cervical radiculopathy. In particular, there are no reports of MRN of brachial plexus involvement in patients with cervical radiculopathy. Methods: We reviewed retrospectively 12 consecutive patients with cervical radiculopathy who underwent 3T MRN. Results: The median age was 54.5 years. Eleven of 12 patients were men. The distribution of nerve‐root signal abnormality was correlated with intervertebral foraminal stenosis and the presence of muscles that exhibited weakness and/or signs of denervation on electromyography. MRN abnormalities were found to extend into the distal part of the brachial plexus in 10 patients. Conclusion: This study demonstrates that MRN is potentially useful for diagnosis in patients with suspected cervical radiculopathy. Moreover, the finding of brachial plexus involvement on MRN may indicate a possible pathophysiological relationship between cervical radiculopathy and brachial plexopathy.
