Congratulations HHAO MEDI® installed non-magnetic stretchers and wheelchairs successfully in Italy

MRI (Magnetic Resonance Imaging) rooms require non-magnetic stretchers and wheelchairs because of the powerful magnetic field generated by the MRI scanner. Here's why:

1. Strong Magnetic Field in MRI

   - MRI machines use superconducting magnets  with fields typically ranging from 1.5 Tesla to 3 Tesla(up to 7 Tesla in research settings). 

   - This magnetic field is always on, even when the machine is not scanning. 

 2. Dangers of Magnetic Objects in the MRI Room

   - Ferromagnetic materials(iron, nickel, cobalt, and some alloys) are strongly attracted to the MRI magnet. 

   - If a regular stretcher or wheelchair (with metal parts) is brought into the MRI room, it can become a dangerous projectile, flying toward the scanner at high speed. 

   - This poses serious risks to patients, staff, and the MRI machine itself. 

 3. Non-Magnetic Equipment is Essential

   - Non-magnetic (MRI-compatible) stretchers and wheelchairs are made from aluminum, titanium, or special plastics that do not interact with the magnetic field. 

   - They ensure: 

     -Patient safety (no risk of being struck by flying metal). 

     - Staff safety (no accidental injuries from moving equipment). 

     - Machine integrity (prevents damage to the MRI scanner). 

 4. Other MRI-Safety Considerations 

   - Even small metal objects (oxygen tanks, tools, keys) can become hazards. 

   - MRI-safe equipment is clearly labeled and rigorously tested. 

Conclusion 

Non-magnetic stretchers and wheelchairs are critical for maintaining a safe MRI environment by preventing projectile accidents and ensuring smooth patient handling.
