Which x-ray procedure is better for checking nerves: MRI or PET Scan?

I don't think there is any question that in your case an MRI is more appopriate. PET will look for glucose uptake so it's extremely useful in finding tumors, looking at lack of brain activity i.e. in the case of Alzheimers, and diagnosing ischemic heart conditions. I've never heard of this usage in PET and I've worked around Nuc Med for 5 years now.

MRI is more anatomical in that it shows contrast between very tissue types much better than a CAT scan would so if you have concerns regarding nerve fibers near bone or other soft tissue. The physican will have better contrast in the MRI than a CAT or PET.

MRI scan is better to view anatomy and structues which are soft... pet scan if u want to find out the function....so the answer is MRI

MRI, but for Functionality PET. BTW, MRI doesn't Use X-Rays At All.

I agree with the ones that listed MRI, for a better diagnosis

MRI is better because it dont use any radioactive substance unlike PET. moreover MRI is more sophisticated than PET
