MRSO Exam Prep GET IT RIGHT THE FIRST TIME !!
MR 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.

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.
The most common patient injuries in the MRI suite - (ANSWER)Burns
The most common objects to undergo significant heating - (ANSWER)Wires and leads.
Objects associated with burns are: - (ANSWER)pulse oximeter sensors and cables, cardiorespiratory monitor
cables, safety pins, metal clamps, drug delivery patches (which may contain metallic foil), and tattoos (which
may contain iron oxide pigment).
The American College of Radiology recommends that ________ and ____________ should be considered a
relative contraindication for MRI - (ANSWER)implanted cardiac pacemakers
implantable cardioverter/defibrillators
Joint Commission checks that procedures are in place for the following safety hazards: -
(ANSWER)Claustrophobic / Anxious patients
