1. What is the primary purpose of an MRI safety policy?
A. To maximize scanner utilization
B. To standardize safe practices and reduce preventable MR-related hazards
C. To reduce the need for patient screening
D. To eliminate the need for staff training
Answer: B. To standardize safe practices and reduce preventable MR-related
hazards
Rationale: An MRI safety policy establishes standardized processes for identifying
hazards, controlling access, screening patients and personnel, managing
equipment, and responding to emergencies. A well-designed policy supports
consistent safety practices rather than focusing primarily on productivity.
2. Which organization publishes the widely used Manual on MR Safety for
healthcare facilities?
A. American College of Radiology (ACR)
B. Federal Aviation Administration (FAA)
C. Occupational Safety and Health Administration (OSHA)
D. American Dental Association (ADA)
Answer: A. American College of Radiology (ACR)
Rationale: The American College of Radiology publishes the Manual on MR Safety,
which provides comprehensive guidance for managing risks associated with the
,MR environment. The current ACR MR Safety webpage identifies the 2026 manual
as the latest edition.
3. Which MR safety hazard is associated with an object being pulled toward the
scanner by the static magnetic field?
A. Acoustic exposure
B. Radiofrequency heating
C. Projectile effect
D. Gradient-induced nerve stimulation
Answer: C. Projectile effect
Rationale: Ferromagnetic objects can experience strong attractive forces in the
static magnetic field and may accelerate toward the magnet. This projectile effect
is a major reason for controlling access to the MR environment and screening
objects before entry.
4. What is the principal purpose of controlled access to the MR environment?
A. To prevent unauthorized individuals from entering areas where MR hazards
may be present
B. To increase the number of examinations performed per hour
C. To prevent contrast reactions
D. To reduce image artifacts
Answer: A. To prevent unauthorized individuals from entering areas where MR
hazards may be present
Rationale: Access control helps ensure that only appropriately screened and
authorized people and equipment enter areas where static magnetic-field hazards
and other MR risks exist. Effective access control is a fundamental component of
an MR safety program.
5. Which item should be verified before bringing equipment into the MR
environment?
,A. Its purchase price
B. Its manufacturer warranty period
C. Its MR safety classification and applicable conditions
D. Its electrical color code
Answer: C. Its MR safety classification and applicable conditions
Rationale: Equipment intended for use in an MR environment must have its MR
safety status established. MR Conditional equipment may only be used when the
specified conditions are satisfied. FDA guidance identifies MR Safe, MR Unsafe,
and MR Conditional labeling as the relevant classifications.
6. What does the term “MR Conditional” mean?
A. The item is safe in every MR environment
B. The item is unsafe in every MR environment
C. The item may be used safely when specified conditions are met
D. The item has not undergone any safety assessment
Answer: C. The item may be used safely when specified conditions are met
Rationale: MR Conditional means that safety has been demonstrated under
defined conditions. These conditions can include magnetic-field strength, spatial
field gradient, SAR limits, dB/dt restrictions, coil restrictions, or other
manufacturer-specified requirements.
7. What should be done when the MRI safety status of a medical device cannot
be established?
A. Treat it as MR Safe
B. Treat it as MR Conditional
C. Use it only during low-SAR sequences
D. Treat it as unsafe until its status is established
Answer: D. Treat it as unsafe until its status is established
Rationale: FDA guidance states that devices without established MR safety
information should be considered unsafe for MR use. Positive identification and
, verification of the applicable safety information are therefore essential before
scanning or bringing such devices into the MR environment.
8. Which component should be included in an effective MRI safety program?
A. Access control
B. Screening procedures
C. Emergency procedures
D. All of these are required components
Answer: A. Access control
Rationale: Access control is a core component of an effective MRI safety program.
It limits entry to individuals who have been appropriately screened, trained, and
authorized. Screening and emergency procedures are also important components,
but the question asks for one specific component rather than an “all of the above”
response.
9. Why should MRI safety policies be reviewed periodically?
A. MRI hazards and clinical practices can change over time
B. The static magnetic field becomes weaker every year
C. Patients eventually become immune to magnetic-field hazards
D. MR equipment never requires policy updates
Answer: A. MRI hazards and clinical practices can change over time
Rationale: Policies should remain aligned with current equipment, technology,
staffing, regulatory expectations, manufacturer instructions, and recognized
safety guidance. The ACR accreditation requirements indicate that MRI safety
policies should be written, enforced, reviewed, and documented at least annually.
10. Which person should have responsibility for implementing the facility's
established MR safety procedures within their assigned duties?
