Well, I had my MRI done today at hospital. I asked tech to show me MRI picture. I saw black spot on S1-L5 and the rest shows white. I don't know if that's normal or not? I took a screenshot of what it looks like... when you see picture, see black one? That's where mine is located at, excatly same one like that one. I hope you can answer my question. Thanks in advance! :)
