1. What is the primary reason an MRI emergency requires specialized
procedures?
A. MRI always produces ionizing radiation
B. The static magnetic field may remain present during an emergency
C. MRI rooms cannot accommodate emergency personnel
D. RF energy continues indefinitely after scanning stops
Correct Answer: B. The static magnetic field may remain present during an
emergency
Rationale: The static magnetic field of many MRI systems is continuously present.
Stopping image acquisition does not necessarily remove the magnetic-field
hazard, so emergency procedures must account for the persistent field.
2. During a medical emergency in the scanner, what should generally happen
before conventional emergency equipment is brought near the magnet?
A. The patient should be moved to a magnetically safe location when feasible
B. The scanner should automatically begin another sequence
C. The RF amplifier should be increased
D. The patient should remain in the bore until the emergency team arrives
Correct Answer: A. The patient should be moved to a magnetically safe location
when feasible
,Rationale: Moving the patient away from the magnet allows conventional
emergency equipment and personnel to be used without exposing them to the
Zone IV magnetic-field hazard. Current MR safety guidance emphasizes rapid and
safe patient removal as a key part of emergency response.
3. Which object presents a classic projectile hazard in an MRI scanner room?
A. Plastic syringe
B. Cotton blanket
C. Ferromagnetic oxygen cylinder
D. Paper chart
Correct Answer: C. Ferromagnetic oxygen cylinder
Rationale: A ferromagnetic oxygen cylinder can experience substantial
translational force toward the magnet and may become a high-energy projectile.
4. What is the most important information to provide conventional emergency
responders before they enter an MR environment?
A. The patient's MRI sequence name
B. The magnet's room temperature
C. The presence and location of the strong magnetic field
D. The patient's preferred emergency medication
Correct Answer: C. The presence and location of the strong magnetic field
Rationale: Emergency responders may carry ferromagnetic equipment. They must
understand the location and hazards of the magnetic field before entering
restricted MR areas.
5. Why should conventional crash carts generally remain outside Zone IV?
A. They interfere with image reconstruction
B. They may contain ferromagnetic components
,C. They increase the patient's heart rate
D. They produce excessive RF pulses
Correct Answer: B. They may contain ferromagnetic components
Rationale: Conventional crash carts can contain ferromagnetic metals and other
equipment that may become dangerous projectiles near the magnet.
6. Which item is most appropriate for use near an active MRI scanner when
emergency equipment is required?
A. Standard steel stretcher
B. Conventional defibrillator
C. MR Conditional emergency equipment meeting its specified conditions
D. Unscreened oxygen cylinder
Correct Answer: C. MR Conditional emergency equipment meeting its specified
conditions
Rationale: Equipment labeled MR Conditional can be used only when its specified
conditions are satisfied. The fact that equipment is used for emergencies does not
eliminate MR safety requirements.
7. A patient presses the emergency call button during scanning. What should
the operator do first?
A. Ignore the signal until the sequence ends
B. Assess the patient's condition and communicate with the patient
C. Immediately quench every superconducting magnet
D. Send an unscreened visitor into Zone IV
Correct Answer: B. Assess the patient's condition and communicate with the
patient
Rationale: The patient alert system is intended to notify the operator of distress or
a problem. Prompt communication and assessment help determine the
appropriate response.
, 8. Why is continuous communication important during an MRI examination?
A. It eliminates all projectile hazards
B. It allows the operator to recognize patient distress promptly
C. It prevents gradient switching
D. It removes the static magnetic field
Correct Answer: B. It allows the operator to recognize patient distress promptly
Rationale: Patients may experience anxiety, pain, heating, breathing difficulty, or
other problems while inside the scanner. Communication provides an important
mechanism for identifying distress.
9. Which event represents a true MR-specific emergency?
A. A patient requesting a blanket
B. A ferromagnetic object becoming attached to the magnet
C. A routine image reconstruction delay
D. A change in room lighting
Correct Answer: B. A ferromagnetic object becoming attached to the magnet
Rationale: A ferromagnetic object attracted to the magnet can create an
immediate projectile or entrapment hazard and requires specialized MR
emergency procedures.
10. A patient is pinned against the magnet by a large ferromagnetic object.
What is the immediate priority?
A. Complete the current imaging sequence
B. Protect the patient from further injury and activate the appropriate emergency
response
C. Increase the scanner's field strength
D. Continue scanning until the object becomes demagnetized
