You can get a second opinion from any radiologist that is willing to read it. You could check at the same place you did the MRI to see if another radiologist there would read it. Or go to a different center. If you are near a university center they should have academic radiologists that would probably give the most complete read. Another option is to call your insurance and ask them where they would cover you to go for a second opinion on the MRI. Whether or not you need just the lumbar spine vs. the entire spine depends on your symptoms, what the original study showed. For example, if it is for disc bulges just in that region, then you don't need the entire spine. There is a cost difference, but each center that does MRI's would charge different prices. Ask the individual MRI center. I hope this is helpful
