PREP 2025/2026 (MOST RECENT!!)
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.

American Board of Magnetic Resonance Safety ABMRS provides
MR Safety Credentialing for: .....ANSWER..... MR Medical
Director (MRMD)
MR Safety Officers (MRSO)
,Page 2 of 72
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
,Page 3 of 72
"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
, Page 4 of 72
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.
