Mild sensory effects due to static • Vertigo
magnetic fields include: • Nausea
• Taste Sensations
Sensory effects of the static magnetic Sensory effects are related to the strength of the

Explain what t-wave artefact is and Any charged particle moving through a magnetic field
why it occurs will have a current induced via this interaction. As
blood, a conductive fluid flows through a magnetic
field it induces an electrical biopotential. This
electrical biopotential can be seen on the ECG
waveform of patients in MRI. It is demonstrated by an
increase in the T-wave amplitude on ECG. This change
in T-wave amplitude is directly proportional to the
strength of the Static Filed. It is important that MR
radiographers are aware of this as elevated T-waves
are also associated with ischemia and myocardial
infarction.
What risks does the static magnetic Static Fields also pose hazards through the
field pose in terms of implants and displacement of ferro-magnetic implants and objects.
objects? The static field imparts both a translation (attractive
force) and a torque (twisting force). The strong nature
of the Static Field also has the potential to disrupt the
function of Cardiac Pacemakers. Anyone entering
beyond the 5G line should be screened for
contraindications to strong Magnetic Fields. Also be
aware of what is being taken over the 5G line.

What strategies can be employed to • Ferromagnetic objects may become airborne - 40
reduce the risks of the static magnetic km/hr terminal velocity possible at 1.5T
field impacting on implants and • Test any metal objects with a hand held magnet
objects? before allowing them to enter the room.
• Keep the general public behind the 5G line. •
Possible contra-indications include pacemakers,
aneurysm clips, intra-vascular coils and stents, heart
valves, penile implants, cochlear implants, ocular
implants (Fatio eyelid springs), neuro stimulators,
bone growth stimulators, drug infusion pumps.
What effect do gradient magnetic Faraday's Law dictates that changing magnetic fields
fields have on patient safety? will generate a voltage and a current in a conductor.
The switching of the gradients induces electrical
currents in conductive tissues. Voltage generation will
occur during the rise and fall times - ie. while the field
is changing. The largest voltages will be generated at
the periphery where the gradient amplitudes are
highest. The most common result of these voltages is
Peripheral Nerve Stimulation (PNS). Other side-effects
are listed below;
• magnetophosphenes - electromagnetically induced
flashes of light
• seizures
• tissue heating
• peripheral nerve stimulation
• muscle contractions
• cardiac arrhythmias
• some degree of patient heating has been shown to
be a result of Gradient Magnetic effects. However, this
has been shown to be so low as to be negligible
What strategies can be employed to In order to keep these effects to a minimum the
keep gradient effects to a minimum? following is recommended.
• keep dB/dT less than those required to produce
peripheral nerve stimulation.
• max limit for dB/dT of 6 Tesla / sec
