MR Safety Officer responsibilities
i. - ✔✔The role of MRSO is often carried out by the senior
ii. Radiographer (in the USA this will generally be an MR technologist), but other suitably
trained
iii. individuals could also fill this role. Multiple MRSOs could be appointed, provided only one
is in charge at
iv. a given time. His/her responsibilities
v. include the following:
•
To be readily accessible and available (eg, to the operators of the MR system) at all times that the MR
facility is accessible.
•
Ensuring that proper policies and procedures for day-today MR safety are enforced.
•
Developing, documenting, and introducing, in conjunction with and under the authority of the
MRMD/MRRD, safe working procedures for the MR environment.
•
Ensuring that adequate written safety procedures, work instructions, emergency procedures, and
operating instructions are issued to all concerned after full consultation with the MRMD/MRRD (and,
if/as needed, the MRSE).
•
Ensuring that appropriate measures for minimizing risks to health that arise from the use of or exposure
to the MR equipment, as per the direction of the MRMD/MRRD, are implemented and monitored.
•
Managing hazards posed by the MR equipment, and monitoring the measures taken to protect against
such hazards.
•
Ensuring that all Heads of Departments and senior medical staff members who are responsible for
personnel who will be involved with the MR system are informed of the formal procedures for training
and authorization.
•
Ensuring that medical, technical, nursing, and all other relevant staff groups (including ancillary
workers)
who may be exposed to the MR environment are educated appropriately on a regular basis as to the
safety requirements
and updated as necessary.
,•
Maintaining records of the personnel who have been educated appropriately as to the safety
requirements.
•
Consulting the MRMD/MRRD (and/or the MRSE)
when further adv

Magnetophosphenes
i. - ✔✔A Sensory Symptom where the subject sees flashing lights caused by an
ii. induced electrical current in the retina when exposed to a strong magnetic field.
•
Bo
- ✔✔Static magnetic field direction
•
dBo/Dx
- ✔✔Gradient magnetic field - Change in Magnetic Field / change in distance
•
American Board of Magnetic Resonance Safety ABMRS provides MR Safety Credentialing for:
i. - ✔✔MR
ii. Medical Director (MRMD)
iii. MR Safety Officers (MRSO)
iv. MR Safety Experts (MRSE)
•
The MRMD certification is designed for:
i. - ✔✔physicians, such as radiologists, who have responsibility for
ii. the safe administration of MR exams.
•
The MRSO certification is designed for:
i. - ✔✔those with a supervisory MRI safety role at the point of
ii. care. While not exclusive to technologists, this role is most frequently be filled by an MR
technologist.
•
The MRSE certification is designed for:
i. - ✔✔those in an expert, technical consulting role who may help
ii. determine the safety of complex conditions. While not exclusive to MR medical physicists,
this role is
iii. most frequently filled by a
iv. medical physicist.
, •
The following types of injury can and have occurred during the MRI scanning process: (8)
i. - ✔✔1.
ii. "Missile effect" or "projectile" injury in which ferromagnetic objects (those having
magnetic properties)
iii. such as ink pens,
iv. wheelchairs, and oxygen canisters are pulled into the MRI scanner at rapid velocity.
v. 2. Injury related to dislodged ferromagnetic implants such as aneurysm clips, pins in
joints, and drug
vi. infusion devices.
vii. 3. Burns from objects that may heat during the MRI process, such as wires (including
lead wires for both
viii. implants and
ix. external devices) and surgical staples, or from the patient's body touching the inside
walls (the bore) of
x. the MRI scanner during the scan. (2)
xi. 4. Injury or complication related to equipment or device malfunction or failure caused by
the magnetic
xii. field. For example, battery-powered devices (laryngoscopes, microinfusion pumps,
monitors, etc.) can
xiii. suddenly fail to operate; some
xiv. programmable infusion pumps may perform erratically; (3) and pacemakers and
implantable
xv. defibrillators may not behave as programmed.
xvi. 5. Injury or complication due to failure to attend to patient support systems during the
MRI. This is
xvii. especially true for patient
xviii. sedation or anesthesia in MRI arenas. For example, oxygen canisters or infusion pumps
run out and staff
xix. must either leave
xx. the MRI area to retrieve a replacement or move the patient to an area where a
replacement can be
xxi. found.
xxii. 6. Acoustic injury from the loud knocking noise that the MRI scanner makes.
xxiii. 7. Adverse events related to the administration of MRI contrast agents.
xxiv. 8. Adverse events related to cryogen handling, storage, or inadvertent release in
superconducting MR
xxv. imaging system sites.
