Cervical myelography in combination with CT myelography is not fully reliable to demonstrate a partial or complete cervical root avulsion. MRI scanning can demonstrate large traumatic meningoceles or additional lesions, such as intramedullary or extradural haematomas, but not a root avulsion. In experimental conditions MR microscopy enables visualization of the avulsed root separated from the spinal cord. The anterior funiculus shows transverse tracts left behind by the avulsion at the original site of the motor fibres. However, the small bore of the current high field magnets and the very long acquisition time makes this method, as yet, unsuitable for application in man.
