Tiatnium earings and MRI?

Because the MRI is a big, powerful magnet, they want anything out your body that would be pulled out of your body by the magnets and hey also want an unobstructed view of what they are taking a picture of, which that would interfere with. I'm guessing they will say out with them. Why do they suspect a tumor, headaches? If so they are caused by tight muscles which an MRI isn't going to show them anyway. They are easily gotten rid of as well if this is why they want to look.
