Superconducting magnets use a special wire which loses all resistance when cooled to -270 degrees Centigrade. This requires liquid helium to surround the magnet wire. Current is applied to the wire during instillation, which generates the magnetic field as it flows. Superconducting magnets are normally FULLY ENERGIZED at all times.. 1 Associate Professor Department: Clinical Laboratory and Nutritional Sciences, University of Massachusetts Lowell, 01854 A.

While MRI is considered to be a safe imaging technique, it is not without hazards. The magnet field will attract many ferromagnetic metals in an uncontrolled fashion and cause them to fly towards the magnets bore and turning them into high velocity projectiles. The bore of the magnet is where the fringe field is strongest, as all the lines of force are constricted and their relative strengths heightened. Various objects can be considered projectiles. experimental design must offer them every practical safeguard whether in research, in teaching or in testing procedures. The need to use an anaesthetic to perform a procedure implies that the pro monitoring of the patient's airway and breathing, nor have we discarded conventional mask techniques altogether. Rather, we suggest our method as a useful addition to the armamentarium of the anaesthe
