Free ARRT MRI Practice Questions
Original questions with explanations
These original ARRT MRI practice questions are educational examples designed to exercise reasoning. They are not recalled exam items and do not imply access to live or confidential test content.
Question 1
A ferromagnetic object enters the MRI scan room. What is the principal hazard?
- A. It can become a projectile in the static magnetic field
- B. Ionizing radiation exposure
- C. Ultrasound heating
- D. Loss of CT calibration
Answer and explanation
A. It can become a projectile in the static magnetic field The static field can accelerate ferromagnetic objects toward the magnet.
Question 2
Increasing repetition time generally has what effect on T1 weighting?
- A. It reduces T1 weighting by allowing more longitudinal recovery
- B. It always increases T1 weighting
- C. It eliminates noise
- D. It reverses gradients
Answer and explanation
A. It reduces T1 weighting by allowing more longitudinal recovery Longer TR reduces differences caused by T1 recovery.
Question 3
Which action is essential before scanning a patient with an implant?
- A. Assume all devices are safe
- B. Remove documentation
- C. Identify the exact device and verify conditions using authoritative MR safety information
- D. Rely on patient confidence
Answer and explanation
C. Identify the exact device and verify conditions using authoritative MR safety information MR Conditional devices require exact identification and adherence to specified conditions.
Question 4
Motion artifact appears in the phase direction. Which response may help?
- A. Increase motion
- B. Ignore the artifact
- C. Turn off screening
- D. Address patient motion and consider appropriate acquisition or phase-direction adjustments
Answer and explanation
D. Address patient motion and consider appropriate acquisition or phase-direction adjustments Motion management and sequence choices can reduce phase-encoding artifacts.
Question 5
What should guide ARRT-MRI preparation?
- A. Recalled live items
- B. The current ARRT MRI content specifications and task inventory
- C. A CT outline
- D. Scanner marketing
Answer and explanation
B. The current ARRT MRI content specifications and task inventory ARRT’s discipline-specific documents define tested knowledge and tasks.
