The rationale behind the ACR's 4-zone strategy is to make it difficult for unqualified staff and unscreened patients to reach the potentially dangerous inner sanctum of the MRI Center (Zone IV) The combined area of Zone 3 and Zone 4 is defined as the MRI Suite. Small metal objects are prohibited in the MRI scan room (Zone 4). Pens, bobby pins, hairclips, etc. must be carefully screened because they can become projectiles that can injure subjects and staff, and damage the MRI equipment. Watches cannot be brought into the MRI scan room. Zone 4- This zone is the actual MRI scanner. In this zone you must be accompanied by either an MRI core staff member or MRI safe staff member. You must have already gone through our MRI safety screening and have all items locked up in locker we provide for you. You will also be given a Red Zone 4 MRI safety sticker to be able to enter this zone At UCSF, each MRI site is divided into 4 safety zones based on the American College of Radiology guidelines: Zone 1: General public area outside the MR environment. This area is the reception and waiting areas. Zone 2: Area between Zone 1 (Public Access) and the strictly controlled Zone 2 (Control Room) and Zone 3 (Magnet)

Ferroguard ® Your MRI Suite. Ferromagnetic objects taken through the MRI door in to Zone IV can lead to serious injury, time consuming delays, and costly damage to your valuable imaging system. When ferrous objects reach the MRI magnet's fringe field, they can be strongly attracted, at high speed, towards the bore of the magnet pacemakers and other ferromagnetic objects into the MRI scanner room. Rigorous MR screening prac-tices will help reduce hazards from contraindicated implants and ferromagnetic objects in close proxim-ity to the MRI scanner. (Pa Patient Saf Advis 2009 Mar;6[1]:20-6.)

typically prohibited in proximity to the MRI scanner, with non-ferromagnetic versions of many tools and devices typically retained by the scanning facility. Patients undergoing MRI examinations are required to remove all metallic objects, often by changing into a gown or scrubs Figure4: Example of a transition between MRI zones 3 and 4. All of these conceptual MRI safety zones have different kinds of hazards, as described on Table 2 [7]. They can range between negligible hazards to bio stimulation interference with medical devices, cryogens, RF heating and attraction effects (missile effect)

However the optimal setup of an FMDS located at the Zone IV door requires it to be set to a level of detection sensitivity that balances safety, with the need to maintain efficient workflow and. Magnetic Resonance (MR) professionals must be able to screen patients, devices, and implants for possible ferromagnetic properties prior to allowing them to enter clinical and research magnetic resonance imaging (MRI) environments and magnet rooms (so-called, Zone III and IV regions). It has also been proposed that all MR sites have ready. ferromagnetic object, drawing it into the scanner with considerable force. The magnetic field is very powerful and can turn everyday hospital items into dangerous projectiles. Such objects will fly into the magnet at tremendous speed and can even pin an adult to the scanner. An object pulled by the magnetic field can often carry a person with it Ferromagnetic objects can become airborne projectiles when placed in a strong magnetic field, moving with a terminal velocity of 60 mph. Level 1 Personnel Level one personnel are individuals who have not had MR safety training MRI sites are divided into 4 safety zones based on the American College of Radiology guidelines: •. Zone 1: General public area outside the MR environment. This area is the reception and waiting areas. •. Zone 2: Area between Zone 1 (Public Access) and the strictly controlled Zone 2 (Control Room) and Zone 3 (Magnet)

In conventional MRI installations it is common to exclude all ferromagnetic items from the scanner room, thus providing a safety margin around the 3 mT contour. In an iMRI suite, ferromagnetic equipment is routinely used within the room, so this approach is not possible: instead, MR Unsafe equipment must be excluded from just a part of the room. Since 2005 ferromagnetic detection systems (FMDS) emerged as devices for alerting staff to possible projectile incidents in MRI. Their value was quickly recognized by the advisory panel of the American College of Radiology and was subsequently included in their guidance document as a safety recommendation. We present an overview of FMDS used for MRI safety All ferromagnetic metal objects are prohibited from the MRI scan rooms. If you don't know if an object is safe, NEVER GUESS. Ask an MRI technologist to check it for you. Remember that a scissors, a wheelchair, an oxygen tank, and many other familiar objects can be deadly in an MRI suite C.Designation of MR safe/MR conditional status Ideally, all object/devices in Zone Ill and IV should be identified with labeling as MR safe, MR conditional, or (in the case of Zone Ill only) MR Unsafe. External devices or objects demonstrated to be ferromagnetic and MR Unsafe or incompatible in the MR environment may still, under specifi Ferromagnetic objects carried into Zone IV can become projectiles that may cause serious injury, death, or equipment failure. MRI machines generate strong magnetic fields and radiofrequencies in the areas within and surrounding the MRI scanner, therefore all individuals must be screened to ensure safety prior to entering Zones III or IV of the.

MRI technical personnel must screen all persons andequipment for ferromagnetic objects prior to entering these zones. The goal of the MRI screening is to obtain a high-quality image to safely andaccurately diagnose a patient. However, this image may not be achieved ifcertain objects interfere. Some implants or metal objects can cause. scanner can cause metallic objects, known as ferromagnetic objects, to move with great force towards the center of the scanner, creating a safety risk to anyone in the way of the projectile. Employees must take precautions to prevent ferromagnetic objects from entering certain areas in the MRI suite Additionally, all non-MRI staff are screened in zone 2 by performing the same activities as patients, completing the MRI safety form and placing into lockers all metal objects, including pagers, mobile phones, pens, keys, wallets, paper clips, identification badges, stethoscopes, and similar objects ferromagnetic metal objects. Ferromagnetic metal objects can become airborne projectiles when placed in a strong magnetic field. The strength of the field increases superlinearly with distance from the magnet bore, and even hand-held objects can be jerked free very suddenly as the holder moves closer to the magnet

Magnetic resonance imaging, or MRI, is a way of obtaining detailed images of organs and tissues throughout the body without the need for x-rays or ionizing radiation. Instead, MRI uses a powerful magnetic field, radio waves, rapidly changing magnetic fields, and a computer to create images that show whether or not there is an injury, disease. The FerrAlert™ Halo II Plus Ferromagnetic Detector guards the entrance into the MRI exam room, providing the most precise and reliable detection and prevention of ferromagnetic threats from entering Zone IV. FerrAlert™ HALO II Plus provides significant assistance in the prevention of serious injury to patients and staff or equipment damage 2. Ferromagnetic objects and the projectile effect The attractive forces between the magnet and all ferromagnetic objects increase significantly as such objects are brought closer to the magnet. All ferromagnetic items brought within the 50 Gauss line will be subject to movement and may be rapidly accelerated into the magnetic field At the top of this form, the following statement is displayed: The MR system has a very strong magnetic field that may be hazardous to individuals entering the MR environment or MR system room if they have certain metallic, electronic, magnetic, or mechanical implants, devices, or objects. Therefore, all individuals are required to fill out.
