RF shielding for MRI rooms is necessary to preventnoise ofradio frequency from entering into theMRI scanner and distorting the image. The three main types of shielding used for MRIs are copper, steel, and aluminum. Copper is generally considered the best shielding for MRI rooms.
RF shielding should not be confused withmagnetic shielding, which is used to prevent the magnetic field of the MRI magnet from interfering withpacemakers and other equipment outside of the MRI room.
After the MRI room has been completely shielded, all utility services such as electrical for lights, air conditioning, fire sprinklers and other penetrations into the room must be routed through specializedfilters provided by the RF shielding vendor.
