MRI Safety Level II
Three field types MRI technologists use to generate an image. - Answer-Static Magnetic Field
Radiofrequency Field
Pulsed Gradient Magnetic Field
T/F: The magnetic field produced by the magnet always remains inside zone 4. - Answer-False
What are the zones and each zone's intended purpose. - Answer-Zone I: General public
Z2: Unscreened MRI patients
Z3: Screened MRI patients & trained personnel
Z4: Screened MRI patients under constant direct supervision of trained MR personnel.
T/F: All MRI facilities must comply with Zone III access requirements? - Answer-False (Older facilities
built before regulations were made may not be able to comply with new standards, but can take
measures to ensure safety)
What is the main concern with regard to the main magnetic field? - Answer-Projectile effect
What are the three classifications applied to all objects entering zone IV? - Answer-MR Safe, MR Unsafe,
& MR Conditional
T/F: MR conditional is an item which has been demonstrated to pose known hazards under specific
conditions. - Answer-True* (The instructional video states "no known hazards under specific conditions",
but as of Feb 2024 the quiz answer is true)
T/F: Crash carts and oxygen cylinders are safe to bring into zone IV? - Answer-False
