Compatibility with MRI and X-ray Scanning
WARNING: You must not wear EmbracePlus during either an MRI or an X-ray scan.
During an X-ray, the doctor will usually ask you to remove all metal
objects since they can affect the quality of the scan. For an MRI, it is
especially important to remove all metal objects because the MRI's
magnets will attract them.
