Did you know?
Paper clips and hairpins pulled into a 1.5 Tesla MRI magnet can reach speeds of up to 40 mph1

Ferromagnetic objects taken through the MRI door into Zone 4 can lead to serious injury, time consuming delays, or costly damage to your valuable imaging system.
When ferrous objects reach the MRI magnet's fringe field, they can be strongly attracted, at high speed, towards the magnet's core. This frightening and dangerous phenomenon is known as the projectile effect.
Who recommends ferromagnetic detection systems (FMDs)?
Regulatory and professional bodies around the world require or recommend ferromagnetic detection systems to protect all MRI facilities

Identifying ferromagnetic hazards
All MRI facilities will have procedures in place that are intended to prevent projectile incidents. However, the number of projectile events continues to rise year on year.
Distinguishing between safe and unsafe items is always a challenge for MRI staff. For example a pair of safe non-ferrous scissors may be visibly identical to a pair of unsafe ferrous scissors. Additionally, the information gained in traditional screening processes may be inaccurate, as patients are not always reliable in reporting all ferrous items on their person or conveying their complete medical history. Ferroguard systems provide valuable objective data to assist the technologist to make accurate safety-decisions to significantly enhance the overall effectiveness of your screening process.
With the increased use of MRI, increasing pressure on patient throughput and the move towards 3T and even stronger magnets, it has never been more important to keep your MRI safety management processes and technology up to date. Remember, the MRI magnet is always on, even when the scanner is not in use.
