MRSO FINAL EXAM: 300 RANDOMIZED SCENARIO-BASED MCQs
Summarized Exam Coverage
The American Board of Magnetic Resonance Safety (ABMRS) MRSO certification exam consists
of 100 multiple-choice, true-false, and multi-answer questions based on seven distinct subject
matter domains. The MRSO certification is designed for those with a supervisory MRI safety role
at the point of care, most frequently filled by an MR technologist. The exam covers: Static
Magnetic Fields, Gradient Magnetic Fields (Time-Varying), Radiofrequency Fields,
Gadolinium/Pregnancy, Facilities/Cryogens, Standards/Regulatory, and Clinical Applications.
DOMAIN 1: STATIC MAGNETIC FIELDS (Questions 1–45)
Question 1
A technologist is preparing to scan a patient when a ferromagnetic oxygen tank is accidentally
brought into the scan room. The tank becomes rapidly attracted to the magnet bore. What is
this phenomenon called?
A) Torque effect
B) Missile effect
C) Faraday effect
D) Lenz effect

Answer: B
The missile effect refers to the rapid acceleration of a ferromagnetic object toward the center of
the magnet due to translational forces.
Question 2
A patient with a programmable ventriculoperitoneal shunt is being screened for MRI. The
device is labeled "MR Conditional." What does this designation mean?
A) The device is safe in any MRI environment
B) The device is safe only under specific conditions such as field strength, gradient, and SAR
C) The device is unsafe in all MRI environments
D) The device has never been tested in MRI
Answer: B
MR Conditional means the device is safe for MRI only under specific conditions, including field
strength, gradient, and SAR limits specified by the manufacturer.
Question 3
A patient with a cardiac pacemaker is being screened for MRI. Which zone does the 5 Gauss line
typically fall within?
A) Zone I
2

,Page 3 of 163
B) Zone II
C) Zone III
D) Zone IV
Answer: C
The 5 Gauss line is the perimeter where the fringe field is strong enough to interfere with
pacemakers and other medical devices, typically located in Zone III.
Question 4
A technologist notices that a patient's ECG tracing shows elevated T waves during an MRI scan.
What is the most likely cause?
A) The patient is having a myocardial infarction
B) The magnetic field is affecting blood flow and ion movement
C) The ECG leads are improperly placed
D) The patient has a fever
Answer: B
The static magnetic field can induce changes in the ECG, particularly elevated T waves, due to
the magnetohydrodynamic effect on blood flowing through the field.

Question 5
A researcher is evaluating a new implant for MRI compatibility. The implant is made of a
material that is weakly repelled by the magnetic field. What type of material is this?
A) Ferromagnetic
B) Paramagnetic
C) Diamagnetic
D) Superparamagnetic
Answer: C
Diamagnetic materials are weakly repelled by magnetic fields, in contrast to ferromagnetic
materials which are strongly attracted.
Question 6
A patient reports seeing flashing lights during an MRI scan. What is this phenomenon called?
A) Magnetophosphenes
B) Nystagmus
C) Vertigo
D) Tinnitus
Answer: A
