Instructions for Safe Use
Personnel and patient exposure to the static magnetic field
The issues related to safety to be considered as regards MR worker and
patient exposure to the static magnetic field, are the biological effects,
projectile effects, safety and compatibility of implanted medical devices
and the compatibility of the peripheral equipment.
MR personnel and patient
☛
Biological effects.
There is no definitive proof that relates short and acute exposure to static
magnetic fields - to an intensity of 2.0 T - and the occurrence of an
irreversible or hazardous bio-effect in a person.
☛
Projectile effect.
The potential risk of the projectile effect of an object in ferromagnetic
material, within a magnetic field, is described in the paragraph “Use
environment”, sub-section “Projectiles” in this chapter.
☛
Implanted medical devices.
A strong magnetic field can influence medical devices implanted in the
body of a person (operator, patient or others) exposed to this field. The
issues regarding implanted medical devices are dealt with in the
paragraph “Pre-screening of patients” in this chapter.
☛
Peripheral equipment.
The static field can interfere with peripheral equipment containing
ferromagnetic components. The issues regarding compatibility of
monitoring equipment are dealt with in the paragraphs “Use
environment”, sub-section “Peripheral equipment”, and “Peripheral
equipment compatibility test” in this chapter.
Do not put cash machine cards or credit cards, mechanical wrist-watches,
floppy disks, magnetic tapes etc. near the magnet. The user must ensure
that these objects remain outside the controlled access area.
The user must ensure observation of all state, federal and/or local
regulations governing exposure of MR worker to static magnetic fields.
The user must also bear in mind that the limits of MR worker exposure to
the static magnetic field may not apply to pregnant women.
In some nations, there may be a requirement that the fetus is not exposed
to a static magnetic field exceeding the limit specified for the public.
In any event the user is recommended to envisage special precautions for
pregnant employees, even though there is currently no epidemiological
proof of negative health effects.
