Anaesthesia is being provided for a claustrophobic adult undergoing an MRI scan in a remote radiology suite. The MRI safety zones divide the area based on magnetic field exposure. Which statement accurately describes Zone III of the MRI suite?

• A The general public area outside the MRI suite
• B The reception and screening area
• C The post-procedure recovery area
• D The room housing the MRI scanner with strict access control ✓

Explanation

The ACR divides the MRI suite into four zones. Zone III is the scanner room where the static magnetic field is always active. Access is strictly restricted, and all equipment and personnel must be screened for ferromagnetic hazards to prevent projectile injuries. Zone I is the public area, Zone II is the screening area, and Zone IV is the scanner bore.
