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.
