In general, owing to high tissue contrast between tissues and multi-planar imaging, MRI is the study of choice to evaluate all lesions in the brain and spine. CT, however, is more sensitive than MRI for the evaluation of calcifications and subtle fractures, and it remains pivotal in the diagnosis of acute subarachnoid hemorrhage.
Nerve damage if severe enough with gross anatomical changes can show up in MRI.
The more diagnostic study would be to do electro-diagnostic studies which can show defect in function of that particular nerve.
Keep me informed if you have any other queries.
