MRSO Exam Prep with Questions and AnswersMR Safety Officer responsibilities - Answer The role of MRSO is often carried out
by the senior
Radiographer (in the USA this will generally be an MR technologist), but other
suitably trained individuals could also fill this role. Multiple MRSOs could be
appointed, provided only one is in charge at a given time. His/her responsibilities
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 advice is required regarding MR safety.
Reporting back to the MRMD/MRRD in a timely fashion any and all MR
safety-related issues.
Ensuring that there is a clear policy for the purchasing, testing, and marking of
all equipment that will be taken into the MR-related critical areas.
Providing and/or ensuring the provision of MR safety education and training in
cooperation with, and as per the policies of the MRMD/MRRD.
Providing safety advice regarding the selection, procurement, and installation of
MR-related equipment (in consultation with the MRSE, if/as needed).
Providing safety advice on the modification of MR protocols (in consultation with
the MRSE, if/as needed).
Maintaining regular contact with other relevant groups or committees
responsible for the safety and welfare of personnel on site, such as, but not
limited to, the local ethics committee and the local safety committee.
Magnetophosphenes - Answer A Sensory Symptom where the subject sees
flashing lights caused by an induced electrical current in the retina when
exposed to a strong magnetic field.
Bo - Answer Static magnetic field direction
dBo/Dx - Answer Gradient magnetic field - Change in Magnetic Field / change in
distance
American Board of Magnetic Resonance Safety ABMRS provides MR Safety
Credentialing for: - Answer MR Medical Director (MRMD)
MR Safety Officers (MRSO)
MR Safety Experts (MRSE)
The MRMD certification is designed for: - Answer physicians, such as
radiologists, who have responsibility for the safe administration of MR exams.
The MRSO certification is designed for: - Answer those with a supervisory MRI
safety role at the point of care. While not exclusive to technologists, this role is
most frequently be filled by an MR technologist.
The MRSE certification is designed for: - Answer those in an expert, technical
, consulting role who may help determine the safety of complex conditions. While
not exclusive to MR medical physicists, this role is most frequently filled by a
medical physicist.
The following types of injury can and have occurred during the MRI scanning
process: (8) - Answer 1. "Missile effect" or "projectile" injury in which
ferromagnetic objects (those having magnetic properties) such as ink pens,
wheelchairs, and oxygen canisters are pulled into the MRI scanner at rapid
velocity.
2. Injury related to dislodged ferromagnetic implants such as aneurysm clips,
pins in joints, and drug infusion devices.
3. Burns from objects that may heat during the MRI process, such as wires
(including lead wires for both implants and
external devices) and surgical staples, or from the patient's body touching the
inside walls (the bore) of the MRI scanner
during the scan. (2)
4. Injury or complication related to equipment or device malfunction or failure
caused by the magnetic field. For example, battery-powered devices
(laryngoscopes, microinfusion pumps, monitors, etc.) can suddenly fail to
operate; some
programmable infusion pumps may perform erratically; (3) and pacemakers and
implantable defibrillators may not behave as programmed.
5. Injury or complication due to failure to attend to patient support systems
during the MRI. This is especially true for patient
sedation or anesthesia in MRI arenas. For example, oxygen canisters or infusion
pumps run out and staff must either leave
the MRI area to retrieve a replacement or move the patient to an area where a
replacement can be found.
6. Acoustic injury from the loud knocking noise that the MRI scanner makes.
7. Adverse events related to the administration of MRI contrast agents.
8. Adverse events related to cryogen handling, storage, or inadvertent release in
superconducting MR imaging system sites.
