MAGNETIC RESONANCE SAFETY OFFICER (MRSO)
EXAM NEWEST 2026-2027 WITH COMPLETE
QUESTIONS AND CORRECT ANSWERS |BRAND
NEW VERSION!
1. Which of the following is a primary safety concern in the
MRI environment?
A. Ionizing radiation
B. Projectile hazards
C. Thermal burns
D. Noise-induced hearing loss
Answer: B, C, D
Rationale: MRI does not use ionizing radiation. Projectile
hazards from ferromagnetic objects, burns from RF-induced
heating, and acoustic noise are primary safety concerns.
2. What is the FDA-approved static magnetic field limit for MR
imaging in clinical settings?
A. 0.5 Tesla
B. 1.5 Tesla
C. 3 Tesla
D. 7 Tesla
,Answer: 3 Tesla
Rationale: The FDA permits MR systems up to 8 Tesla for adults
in clinical use; commonly 3 Tesla is used. Higher fields are used
mainly in research.
3. Which patient condition requires extra caution due to MRI
safety?
A. Pacemaker
B. Cochlear implant
C. Pregnancy
D. Diabetes
Answer: A, B, C
Rationale: Pacemakers and cochlear implants may be unsafe in
MRI. Pregnancy requires risk assessment. Diabetes itself is not a
direct MRI safety concern.
4. What does the term “projectile effect” refer to?
A. Movement of metallic objects into the magnet
B. Accidental radiation exposure
C. Electric shock from the scanner
D. Patient claustrophobia
Answer: A
Rationale: Ferromagnetic objects can become projectiles due
to the strong magnetic field.
,5. What is the primary hazard of the MRI radiofrequency (RF)
field?
A. Tissue heating
B. Loud noise
C. Oxygen depletion
D. Ionizing radiation
Answer: A
Rationale: RF energy can cause tissue heating or burns,
particularly if conductive materials are in contact with skin.
6. Which MRI safety zone is designated for uncontrolled
access by the general public?
A. Zone I
B. Zone II
C. Zone III
D. Zone IV
Answer: Zone I
Rationale: Zone I is freely accessible. Zones III and IV are strictly
controlled due to higher magnetic field exposure.
7. What type of implants are considered MR Conditional?
A. Safe under all conditions
B. Unsafe in any MR scanner
, C. Safe only under specified conditions
D. Requires surgical removal before MRI
Answer: C
Rationale: MR Conditional devices have specific conditions for
safe imaging (e.g., field strength, positioning).
8. Which personnel should receive MRI safety training?
A. Radiology staff
B. Cleaning staff
C. Patient transporters
D. All staff entering Zones III and IV
Answer: D
Rationale: Anyone entering high-field MRI zones must be
trained in MRI safety to prevent accidents.
9. What is the main concern for patients with tattoos in MRI?
A. Skin irritation from contrast
B. RF-induced heating of tattoo pigments
C. Allergic reaction to ink
D. Magnetic interference with tattoos
Answer: B
Rationale: Some tattoo pigments contain metallic particles that
can heat during MRI.
