Which zone is the outermost area where the public can access without MR safety screening?

• A. Zone 4
• B. Zone 3
• C. Zone 2
• D. Zone 1

Answer: (D)

MR safety zones define how people move into the MRI environment. The outermost zone, Zone I, is the public area outside the MR suite and does not require MR safety screening. This is where visitors and the general public can be present without screening. Moving inward, Zone II covers areas like reception and waiting rooms that are still outside the actual MR rooms but may lead toward them. To reach the scanner, access passes into Zone III, a restricted area where MR safety screening is required before entry, and Zone IV is the MRI room itself with the highest level of safety controls. So, the outermost area that can be accessed without MR safety screening is Zone I.
