Regulatory and professional society MR imaging safety guidelines have standardized many aspects of MR imaging site design, patient safety, and personnel workflow. The MRI safety audit provides a tangible way for your facility to identify and correct any issues that can potentially cause a safety incident. New strategies for building safety into the design and construction of the MRI suite will further minimize the hazards to patients, staff and health care institutions. The MRI environment has specific safety concerns related to the static magnetic field: Medical devices may malfunction within the static magnetic field, placing individuals with these devices at risk for serious or fatal injury, Other ferromagnetic items inadvertently taken into the static magnetic field pose a projectile risk and have been known to cause fatal trauma to patients, staff and others, In addition to the static field, MRI systems use large liquid helium reserves which, if accidentally released, pose a hazard to those in the vicinity (i.e., potential for asphyxiation and cryogen burns), MRI system quenches can be dangerous for individuals unaware of the associated risks and the required emergency procedures within the MRI environment, Controlling access to the MRI environment is instrumental in, Preventing accidents and reducing risk for serious or fatal injury, Ensuring medical devices and MRI scanning systems are not damaged and/or rendered useless, Mitigating system downtime and maintaining a safe and effective working environment, A four zone facility design is used to control and restrict access to the MRI environment, The facility is conceptually divided into zones that physically restrict access of health care personnel into areas of danger due to proximity to the static magnetic field, Zone I – Access to general public for example reception or waiting areas, Zone II – Access to unscreened individuals; for example, change and preparation areas, Zone III – Physically restricted barrier and consists of areas that have immediate access to the magnet room for example the control room, Zone IV – Physically confines the magnet room or areas where the 5 gauss fringe field extends. Transient changes in MR Zones can occur in dynamic MR environments; that is, a space that may be Zone IV in one instance and convert to Zone III at another time. Alterations performed by a facility on MR Safe, MR Unsafe, and MR Conditional equipment or devices may alter the compatibility properties of the device, which has the potential to cause damage to the device/object or anyone near the device/object. 1. structures.
