Mild sensory effects due to static • Vertigo
magnetic fields include: • Nausea
• Taste Sensations
Sensory effects of the static Sensory effects are related to the strength of the
magnetic field increase or decrease magnetic field with few symptoms at 1.5T and more
with field strength? appearing approaching a 4T field strength

Explain what t-wave artefact is and Any charged particle moving through a magnetic
why it occurs field 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 km/hr terminal velocity possible at 1.5T
magnetic field impacting on implants • Test any metal objects with a hand held magnet
and 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 have on patient safety? fields 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
