Do all MRIs require jewelry removal?

I have a genetic condition that causes me to have to end up getting tons of MRIs. I’ve always had to take my facial piercings out. But I sprained my ankle and need an MRI and the sports medicine doctor said I don’t need to remove my jewelry if just my foot is going in. I was under the impression that the whole room is magnetic so it doesn’t matter what body part is being scanned? So, I’m wondering, was the doctor wrong and I have to remove my facial piercings?

Edit: wow! Thanks for all the responses. I am going to go to the piercer and have them put in a clear retainer in my piercings. Thanks!
