A+| MAGNETIC RESONANCE SAFETY OFFICER EXAM
PREP 2026/2027 (MOST RECENT!!)
1. What are the four MRI safety zones as defined by the ACR?
A) Green, Yellow, Orange, Red
B) Zone I, Zone II, Zone III, Zone IV
C) Controlled, Uncontrolled, Restricted, Public
D) Screening, Preparation, Scanning, Recovery
Answer: B) Zone I, Zone II, Zone III, Zone IV
Rationale: The ACR guidance document defines four safety
zones: Zone I (generally accessible to the public), Zone II (patient
screening and preparation), Zone III (physically restricted area
with potential for injury), and Zone IV (magnet room itself) .
1
,2. In which zone should patients change out of their street
clothes?
A) Zone I
B) Zone II
C) Zone III
D) Zone IV
Answer: B) Zone II
Rationale: Patients should change into MRI-safe attire in Zone II,
which is the patient preparation and screening area before
entering the restricted Zone III .
3. What takes place in Zone II?
A) The actual scanning procedure
B) Public access and reception
C) Screening, changing, and ferromagnetic detection
2
, D) Magnet quench activation
Answer: C) Screening, changing, and ferromagnetic detection
Rationale: Zone II is where patient screening occurs, patients
change into appropriate attire, and ferromagnetic detection
screening is performed before entering Zone III .
4. What takes place in Zone IV?
A) Patient screening
B) Public waiting area
C) The scanning procedure
D) Control room operations
Answer: C) The scanning procedure
Rationale: Zone IV is the magnet room itself where the actual
MRI scanning takes place. This is the highest risk zone .
5. Zone III regions should be physically restricted from general
public access by:
3
, A) Warning signs only
B) Key locks, passkey locking systems, or other reliable
physical restriction
C) Verbal instructions only
D) Line-of-sight observation only
Answer: B) Key locks, passkey locking systems, or other reliable
physical restriction
Rationale: Zone III must be physically restricted using key locks,
passkey systems, or other reliable methods to prevent
unauthorized access .
6. Any area 5 gauss or higher is Zone ________ and must have
________ access.
A) I / unrestricted
B) II / monitored
C) III / restricted
