The quick answer is yes, if it's from us.

One of the many advantages of titanium jewelry, on top of its biocompatibility, is that it is completely nonmagnetic. This means it’s completely safe for MRI scans, X-rays, CT scans, PET scans, etc. The only time it could be an issue is when the jewelry could block the view during the scan, say nipple piercings in a lung X-ray. If your doctor still insists your jewellery needs to come out, you may have to look at taking them out the jewellery and repiercing in the future. We do carry glass retainers for healed piercings.
