MRSO EXAM PREP WITH QUESTIONS ANDVERIFIED ANSWERS
MR Safety Officer Responsibilities - ANSWER The function of MRSO is often
performed by a senior radiographer (typically an MR technician in the US),
however, other qualified individuals can also take on this role. Multiple MRSOs
could be appointed, but only one can be in control at any given time. His or her
responsibilities include:
To be easily accessible and available (for example, to the MR system operators) at
all times when the MR facility is open.
Ensuring that appropriate rules and procedures for day-to-day MR safety are
followed.
Safe working procedures for the MR environment are being developed,
documented, and implemented in collaboration with and under the authority of the
MRMD/MRRD.
Ensure that suitable documented safety protocols, work instructions, emergency
procedures, and operational instructions are distributed to all parties involved
following thorough consultation with the MRMD/MRRD (and, if necessary, the
MRSE).
Ensure that suitable procedures for reducing health hazards associated with the use
or exposure to MR equipment, as directed by the MRMD/MRRD, are adopted and
monitored.
Managing the hazards posed by the MR equipment and monitoring the precautions
taken to defend against them.
,Ensure that all Heads of Departments and senior medical staff members
accountable for people who will use the MR system are aware of the official
training and authorization procedures.
Ensure that medical, technical, nursing, and all other relevant staff groups
(including ancillary workers) who may be exposed to the MR environment are
appropriately informed regularly about the safety requirements.
and updated as needed.
Maintaining records of personnel who have received proper safety training.
Consult the MRMD/MRRD (and/or the MRSE).

A medical physicist.
The following forms of injuries can and have happened during the MRI scanning
process: (8) - ANSWER 1. "Missile effect" or "projectile" injury occurs when
ferromagnetic materials (those with magnetic qualities), such as ink pens,
Wheelchairs and oxygen canisters are dragged inside the MRI scanner at high
speed.
2. Injuries caused by dislodged ferromagnetic implants such as aneurysm clips,
joint pins, and drug infusion devices.
3. Burns caused by things that may burn during the MRI process, such as wires
(including lead wires for both implants and
external devices), surgical staples, or from the patient's body hitting the interior
walls (the bore) of the MRI scanner.
Throughout the scan. (2)
4. Injury or complication caused by a magnetic field-induced malfunction or
breakdown of equipment or a device. For example, battery-powered gadgets
(laryngoscopes, microinfusion pumps, monitors, etc.) can suddenly cease to
perform; some
Programmable infusion pumps may operate erratically, and pacemakers and
implantable defibrillators may not function as intended.
