I have a Medtronic Stimulator and it is very difficult to locate a safe MRI machine and I am in need of one to check my DDD etc. In Dallas/East TX.

Check with Medtronic. Most new gen Medtronic spinal stimulators are mri friendly. Check with your surgeon or with the u.s website ,it will be able to confirm it. It will save you money and hassle, otherwise a ct myleogram might be an option.
