Question 1
What is the primary purpose of MRI patient screening?
A. Determine the patient's preferred imaging sequence
B. Identify conditions or objects that could create an MR safety hazard
C. Estimate the patient's examination time
D. Determine whether contrast will improve image quality
Correct Answer: B. Identify conditions or objects that could create an MR safety
hazard
Rationale: MRI screening is designed to identify implants, metallic foreign bodies,
devices, and other conditions that may create risks from the static magnetic field,
gradient fields, RF energy, or the MR environment.
Question 2
Which item should be specifically addressed during routine MRI screening?
A. The patient's favorite sleeping position
B. The patient's occupation
C. A history of implanted medical devices
D. The patient's preferred appointment time
Correct Answer: C. A history of implanted medical devices
,Rationale: Implanted devices can present magnetic attraction, torque, heating,
malfunction, or other hazards. Their presence and exact identity should therefore
be established before MRI.
Question 3
Which finding should prompt further investigation before an MRI examination?
A. History of wearing eyeglasses
B. History of an implanted cardiac device
C. Preference for a quiet examination
D. Previous ultrasound examination
Correct Answer: B. History of an implanted cardiac device
Rationale: Cardiac implantable electronic devices may have specific MR
conditions. The exact system and applicable scanning requirements must be
verified before proceeding.
Question 4
What is the most appropriate action when a patient cannot provide adequate
information about an implanted device?
A. Assume the device is MR Safe
B. Proceed using the lowest available field strength
C. Verify the device through reliable documentation before scanning
D. Ask the patient to remove the device
Correct Answer: C. Verify the device through reliable documentation before
scanning
Rationale: An unknown implant cannot safely be assumed to be compatible with
MRI. Reliable identification allows the applicable MR conditions or
contraindications to be determined.
Question 5
,What does the term MR Safe indicate?
A. The item is safe only at 1.5 T
B. The item poses no known hazards in any MR environment
C. The item can enter the scanner only under manufacturer-specific conditions
D. The item is safe only when the patient is sedated
Correct Answer: B. The item poses no known hazards in any MR environment
Rationale: MR Safe refers to an item that poses no known hazards resulting from
exposure to the MR environment.
Question 6
What does MR Conditional mean?
A. The device is always unsafe
B. The device is safe only outside the MRI department
C. The device can be used safely under specified conditions
D. The device has not been evaluated for MRI
Correct Answer: C. The device can be used safely under specified conditions
Rationale: MR Conditional devices may be used in the MR environment only when
the specified conditions are satisfied. These may include field strength, spatial
gradient, RF exposure, positioning, or other requirements.
Question 7
A patient reports having a metallic object placed during surgery several years ago
but does not know what it is. What should the MRI team do?
A. Assume it is stainless steel
B. Determine the exact device or obtain appropriate documentation
C. Proceed if the surgical scar is healed
D. Ask the patient to cover the area with clothing
Correct Answer: B. Determine the exact device or obtain appropriate
documentation
, Rationale: The age of an implant does not establish its MR safety. Device identity
and applicable safety information should be confirmed before scanning.
Question 8
Why is a history of previous metal injury important during MRI screening?
A. Metal fragments may remain in the body and pose an MR hazard
B. Metal injuries always cause chronic pain
C. Previous metal exposure prevents use of MRI contrast
D. Metal injuries always make MRI images unusable
Correct Answer: A. Metal fragments may remain in the body and pose an MR
hazard
Rationale: Previous injuries involving metal, particularly high-velocity fragments,
may leave retained metallic foreign bodies that can potentially move or heat
during MRI.
Question 9
Which history is particularly important when assessing the possibility of an
intraocular metallic foreign body?
A. Previous exposure to loud music
B. Previous metal grinding or cutting injury
C. Previous dental cleaning
D. Previous routine blood testing
Correct Answer: B. Previous metal grinding or cutting injury
Rationale: Activities such as metal grinding can produce small high-velocity
fragments capable of entering the eye. A suspected metallic intraocular foreign
body requires appropriate evaluation before MRI.
