1. What is the primary purpose of screening MRI personnel before they enter
restricted MRI areas?
A. To determine their ability to operate the scanner
B. To assess their knowledge of image interpretation
C. To identify conditions or objects that could create an MRI safety hazard
D. To determine whether they require contrast media
Rationale: Personnel screening is intended to identify implants, devices, metallic
objects, or other conditions that could create hazards in the MR environment.
Screening is a fundamental safety barrier before personnel enter restricted areas.
2. When should MRI personnel screening normally occur for an employee who
will work in the MRI environment?
A. Only after an MRI-related incident
B. As part of the employment or assignment screening process
C. Only when the employee operates the scanner
D. After the employee's first MRI examination
Rationale: Personnel who may work in the MR environment should undergo
appropriate screening before being permitted to enter controlled MRI areas. Early
screening helps identify potential hazards before exposure occurs.
3. Which personnel should be considered for MRI safety screening?
,A. Only MRI technologists
B. Only physicians
C. Only patients
D. All individuals who may enter the relevant controlled MRI environment
Rationale: MRI hazards can affect anyone entering the controlled environment,
not just scanner operators. Screening requirements should therefore apply to
personnel and other individuals according to the facility's access policies.
4. Which item is particularly important to identify during personnel screening?
A. Employee's preferred work schedule
B. Implanted medical devices
C. Employee's educational degree
D. Employee's job title
Rationale: Implanted medical devices can interact with static magnetic fields,
gradient fields, or RF energy. Their presence and MRI safety status must be
evaluated before the individual enters restricted areas.
5. Why should personnel be asked about previous surgeries during MRI
screening?
A. Surgery determines MRI image contrast
B. Surgery determines hearing-protection requirements
C. Surgery may have resulted in an implanted device, metallic material, or
retained foreign body
D. Surgery determines the MRI room temperature
Rationale: Surgical procedures can introduce implants, clips, wires, prostheses, or
other materials into the body. A history of surgery can therefore identify
information requiring further MRI safety evaluation.
6. An MRI employee recently underwent a procedure involving a potentially
ferromagnetic object. What is the most appropriate action?
,A. Continue entering Zone III without reporting it
B. Wait until the next annual training session
C. Report the procedure to the appropriate MR safety authority for
reassessment
D. Test the object by approaching the magnet
Rationale: A new procedure can change an employee's MRI safety status.
Personnel should report relevant procedures or injuries so that appropriate
screening and safety evaluation can be performed.
7. Which type of object presents a major projectile hazard in an MRI
environment?
A. Paper document
B. Cotton towel
C. Plastic badge without metal components
D. Ferromagnetic oxygen cylinder
Rationale: Ferromagnetic objects can experience strong attraction toward the
magnet. Large objects such as oxygen cylinders can become extremely dangerous
projectiles.
8. What does the term “ferromagnetic” describe in the context of MRI safety?
A. A material that produces only acoustic noise
B. A material that can experience strong attraction and magnetic forces in an
MR field
C. A material that cannot interact with magnetic fields
D. A material used exclusively for RF shielding
Rationale: Ferromagnetic materials can be strongly attracted to magnetic fields
and may also experience torque. These properties make them important hazards
in MRI.
, 9. Why should personnel not rely solely on visual inspection when screening
themselves for MRI safety?
A. Visual inspection is unnecessary for MRI
B. Some hazardous items may be concealed, overlooked, or not visually obvious
C. MRI hazards are visible only on radiographs
D. Visual inspection measures magnetic field strength
Rationale: Items may be hidden in pockets, incorporated into clothing, or present
as implants or retained foreign bodies. A structured screening process is more
reliable than visual inspection alone.
10. What is an important reason for screening personnel even if they have
worked around MRI equipment for years?
A. The magnetic field becomes stronger with employee experience
B. Their medical history or implanted devices may have changed
C. Experienced personnel are more susceptible to acoustic noise
D. MRI scanners require annual employee identification
Rationale: A person's MRI safety status can change because of surgery, injury,
implantation of a device, or other medical events. Previous safe entry does not
guarantee continued safety.
11. Which event should prompt an MRI employee to report for possible
rescreening?
A. Changing their work shift
B. Receiving a new employee identification card
C. Undergoing surgery that may introduce metallic material
D. Completing annual MRI training
Rationale: Surgery involving metallic or implanted materials can alter the
employee's risk profile. Such changes should be reported and evaluated before
further access to restricted MRI areas.
