Magnetic resonance examination system, inspection mechanism and magnetic resonance examination mechanism before the art, inspection mechanism is by the metal scanning room before the art, the changeroom, shower room and psychological consultation room are constituteed, set up a plurality of wardrobes in the changeroom, the metal scanning room, the changeroom, shower room and psychological consultation room communicate with each other in proper order, magnetic resonance examination mechanism includes the nuclear magnetic resonance room, set up the nuclear magnetic resonance finder in the nuclear magnetic resonance room, be connected an intercommunication corridor between metal scanning room and the psychological consultation room, be connected an intercommunication corridor between metal scanning room and the nuclear magnetic resonance room, be connected an intercommunication corridor between changeroom and the nuclear magnetic resonance room. The utility model discloses a magnetic resonance examination person provides the preceding checkout system of art of a system, lets and treat that the latent hazards of inspector fully expose and take corresponding therapeutical measure in inspecting before the art, can reduce the magnetic resonance examination risk effectively, guarantees going on smoothly of nuclear magnetic resonance, has the advantage that safe and reliable and checking efficiency are high.
