An MRI device and method that reduce radio-frequency (RF) interference and the effect of the MRI's magnet, within an active RF-magnetic environment. The device includes a non-fringing magnetic field resonance MRI device having RF shielding means. The method includes: obtaining a UNF-MRD, and embedding or otherwise connecting an RF shielding means within or to the UNF-MRD to provide the same with a radio interference immunity (RII) from its RF-electromagnetic environment.
