Question 1
What is the first priority during a serious medical emergency involving a patient in
the MRI scanner?
A. Complete the current imaging sequence
B. Protect the MRI equipment from damage
C. Provide appropriate emergency care and ensure the patient's safety
D. Preserve the planned examination time
Correct Answer: C
The patient's safety and emergency medical needs take priority over completing
the examination. MRI-specific hazards must still be considered while initiating the
emergency response.
Question 2
What is a major concern when responding to a medical emergency inside Zone
IV?
A. The scanner may automatically change the patient's diagnosis
B. Emergency equipment and personnel may introduce MR hazards
C. The patient cannot receive oxygen under any circumstances
D. The MRI table cannot be moved
,Correct Answer: B
Zone IV contains the scanner's strongest magnetic-field hazards. Emergency
responders and equipment must therefore be appropriately screened or otherwise
managed before entering the area.
Question 3
Why should emergency responders receive MRI-specific safety training?
A. MRI training improves their ability to interpret images
B. They may otherwise unknowingly bring ferromagnetic equipment into the
MR environment
C. It allows them to modify MRI sequences
D. It eliminates the need for hospital emergency procedures
Correct Answer: B
Emergency responders may routinely use equipment that is safe elsewhere but
dangerous near an MRI magnet. Training helps them recognize and avoid MR-
specific hazards.
Question 4
Which action is generally appropriate when a patient requires emergency medical
treatment during an MRI?
A. Keep the patient in the scanner until treatment is complete
B. Move the patient to a designated safe location outside the immediate MR
hazard area when necessary
C. Bring a conventional crash cart directly into Zone IV
D. Quench the magnet automatically for every medical emergency
Correct Answer: B
Emergency care may require removing the patient from the scanner and MR
hazard area before definitive resuscitation. The facility's emergency procedure
should define the appropriate route and destination.
,Question 5
What is the primary purpose of an Emergency Power Off (EPO) control?
A. To permanently remove the magnetic field
B. To rapidly shut down electrical power to designated MRI equipment or
systems
C. To release cryogen into the room
D. To increase the magnet's field strength
Correct Answer: B
An EPO is intended to interrupt electrical power to designated systems. It is
distinct from an Emergency Magnet Off/quench system, which is specifically
associated with rapidly reducing the magnetic field in applicable superconducting
systems.
Question 6
What is the primary function of an Emergency Magnet Off system on an
applicable superconducting MRI system?
A. To stop only the RF transmitter
B. To disable the patient table
C. To rapidly reduce the main magnetic field through magnet de-
energization/quench
D. To activate the room's fire alarm
Correct Answer: C
Emergency Magnet Off, often called a quench button on superconducting systems,
initiates a process intended to rapidly reduce the static magnetic field. Because
quenching has significant consequences and hazards, it should be used
deliberately according to site procedures.
Question 7
, Which situation may justify serious consideration of an Emergency Magnet Off
procedure?
A. A routine patient who wants to stop the examination
B. A minor image-quality artifact
C. A situation requiring emergency responders to enter a hazardous Zone IV
where appropriate screening cannot be accomplished
D. A patient requesting a different imaging sequence
Correct Answer: C
If an emergency requires unscreened responders or ferromagnetic emergency
equipment to enter Zone IV, deliberate quenching may need to be considered
according to the facility's emergency policy. The ACR emphasizes that this decision
should be deliberate because quenching carries its own hazards.
Question 8
Why should an Emergency Magnet Off button not be activated automatically for
every medical emergency?
A. It never affects the magnetic field
B. Quenching carries significant operational and safety consequences
C. It increases the magnet's field strength
D. It prevents emergency personnel from treating the patient
Correct Answer: B
Quenching a superconducting magnet can rapidly release cryogen and create
additional hazards. Therefore, the decision to quench should be deliberate and
based on the circumstances and facility procedure.
Question 9
What can occur during a quench of a traditional superconducting MRI system?
A. RF energy is converted into X-rays
B. Cryogen rapidly changes state and is released as gas through the cryogen vent
