Question 1
What is the primary purpose of screening a patient before an MRI examination?
A. To determine the patient's preferred imaging position
B. To estimate the examination duration
C. To identify potential MRI safety hazards
D. To select the radiologist who will interpret the study
Correct Answer: C. To identify potential MRI safety hazards
Rationale: MRI screening is primarily intended to identify conditions, implants,
devices, metallic foreign bodies, and other factors that could create a safety risk in
the MR environment. This screening occurs before the patient enters areas where
the static magnetic field or other MR-related hazards may pose a danger.
Question 2
Which item should generally be removed before a patient enters the MRI scanner
room?
A. Plastic hospital identification band
B. MR-conditional monitoring equipment approved for the examination
C. Nonmetallic pillow
D. Metallic jewelry
Correct Answer: D. Metallic jewelry
,Rationale: Metallic jewelry can become a projectile hazard or interact with the
MRI environment. Jewelry should be removed before the patient enters the
scanner environment unless it has been specifically assessed and determined to be
safe.
Question 3
A patient reports having an implanted medical device but does not know its
manufacturer or model. What is the most appropriate preparation step?
A. Proceed because all modern implants are MRI compatible
B. Obtain information needed to determine the device's MR safety status
C. Ask the patient to sign a waiver and continue
D. Place the patient in the scanner briefly to test the device
Correct Answer: B. Obtain information needed to determine the device's MR
safety status
Rationale: An implanted device should not be assumed to be safe simply because
it is modern or commonly used. The device identity and applicable MR safety
conditions should be established before proceeding. This may require medical
records, implant documentation, manufacturer information, or other reliable
sources.
Question 4
Why should a patient be asked about previous metal injuries involving the eyes?
A. Metallic fragments may pose a risk in the magnetic field
B. Eye injuries always prevent MRI examinations
C. Metal fragments increase acoustic noise
D. Eye injuries interfere with patient positioning
Correct Answer: A. Metallic fragments may pose a risk in the magnetic field
Rationale: A history of orbital metallic foreign-body injury is important because
ferromagnetic material near the eye may move or experience magnetic forces
during MRI. Appropriate evaluation is required when such a history is suspected.
,Question 5
Which type of clothing is most appropriate for a patient entering the MR scanner
environment?
A. Clothing containing metal snaps and zippers
B. Clothing with hidden metal undergarment fasteners
C. MR-safe clothing free of hazardous metallic components
D. Heavy clothing containing decorative metallic fibers
Correct Answer: C. MR-safe clothing free of hazardous metallic components
Rationale: Patients should be provided with appropriate MR-safe attire when
necessary to prevent metallic objects or components from entering the scanner
environment. ACR guidance specifically addresses the use of MR-safe attire and
reliable removal of metallic personal belongings.
Question 6
Which patient item should be specifically checked because it may contain a
hidden metallic component?
A. Cotton towel
B. Hair accessory
C. Paper medical record
D. Plastic water cup
Correct Answer: B. Hair accessory
Rationale: Hair accessories such as clips, pins, extensions, and some decorative
items may contain metal. These items should be removed or assessed before the
patient enters the MR environment.
Question 7
A patient uses a hearing aid. What should the MRI technologist do before the
patient enters the scanner?
, A. Leave it in place because hearing aids are always MR Safe
B. Remove or appropriately assess it according to its MR safety status
C. Cover it with a towel
D. Place it inside the patient's clothing
Correct Answer: B. Remove or appropriately assess it according to its MR safety
status
Rationale: Hearing aids can contain electronic or metallic components and are not
automatically safe for MRI. The device should be removed when required or
specifically evaluated according to its labeling and the conditions of use.
Question 8
Why is it important to ask about implanted electronic devices during MRI
preparation?
A. They can interact with the MRI environment
B. They always cause severe image distortion
C. They make the patient unable to hear instructions
D. They prevent the use of positioning cushions
Correct Answer: A. They can interact with the MRI environment
Rationale: Implanted electronic devices may be affected by the static magnetic
field, gradient fields, or radiofrequency energy. Their MR safety status and any
conditions for scanning must therefore be established before the examination.
Question 9
Which patient should receive additional attention during the MRI screening
process?
A. A patient wearing cotton clothing
B. A patient with a documented implanted device
C. A patient carrying a paper appointment card
D. A patient who has previously had an ultrasound
