MRSO Latest updated Exam with verified detailed answers || || || || || || ||
MR Safety Officer responsibilities - correct 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.

for: - correct answer✔✔MR Medical Director (MRMD)
|| || || || || ||
MR Safety Officers (MRSO)
|| || ||
MR Safety Experts (MRSE)
|| || ||
, The MRMD certification is designed for: - correct answer✔✔physicians, such as
|| || || || || || || || || || ||
radiologists, who have responsibility for the safe administration of MR exams. || || || || || || || || || ||
The MRSO certification is designed for: - correct 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: - correct 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) -
|| || || || || || || || || || || || || || || ||
correct 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. || || || || || ||
