Inside magnet room, all ferromagnetic objects must be removed?

• A. Zone 1
• B. Zone 4
• C. Zone 2
• D. Zone 3

Answer: (B)

The main idea is that the MRI magnet creates a very strong magnetic field, and any ferromagnetic object can be violently pulled toward the magnet. This poses serious risk of injury, as well as potential damage to the scanner and implants. Because of this, the area that houses the magnet—the magnet room—requires all ferromagnetic items to be removed or thoroughly screened before entry. This is why the rule is that ferromagnetic objects must be removed when entering that space. Remember examples of ferromagnetic items: items containing iron or steel, like jewelry, watches, coins, certain tools, oxygen tanks, and metallic medical devices, which should not be brought into the magnet room. Other surrounding zones are less restricted, but the magnet room itself demands removal to prevent dangerous attraction to the magnet.
