As in any medical facility, the MR suite should be equipped with emergency medical supplies on a crash cart. These emergency supplies should be located in Zone 2 or 3. Many of these supplies can be dangerous in Zone 4. For this reason, in any medical emergency, all patients should be removed from the scan room to a predetermined magnetically safe location in Zone 2 or 3 before resuscitation begins. Restricted access to Zone 4 must be maintained during resuscitations and other emergent situations.
