MRI Scanner – MR Classification System

The MRI scanner uses radio waves and powerful magnets to create detailed images of the body. Because the magnetic field presents a hazardous atmosphere around certain items, hospitals and MRI facilities use an item classification system so that potentially dangerous items are not brought near the MRI scanner.

Potentially magnetic items must be tested before entering the controlled access areas of the MRI facility. Only items that are proven to be safe near that particular MR environment are allowed inside the MR Suite. When an item is tested, it is classified as MR Safe, MR Conditional or MR Unsafe. Specific icons, usually in the form of stickers, identify the category of each item. These icons may be reproduced in black and white; however, the use of color is encouraged because of added visibility.

MR Safe items pose no known hazards in all MR environments and are indicated by a green and white icon. Conversely, MR Unsafe items, such as any magnetic item, are unsafe in all MR environments. The MR Unsafe icon features “MR” inside of a red circle with a bar through it. Any items not clearly marked should be considered MR Unsafe. Finally, MR Conditional items do not pose any known hazards in a specific MR environment with specific conditions of use. The MR Conditional icon consists of “MR” inside of a yellow triangle.

Never bring MR Conditional items into the MR suite, and especially near the MRI scanner, without prior approval from MRI personnel. Most transports and medical devices will be designated as MR Conditional, so safety within the facility depends on knowing what the specific conditions are for each object.

Labeling items and following the MR Item Classification System helps prevent dangerous situations for both staff and patients within the MRI facility.

Hospital and MRI facility personnel that work near the MRI scanner must be aware of the powerful magnetic field and its associated hazards. For personnel not formally trained in a Radiology program, a safety program should be established for each individual facility. To supplement MRI safety, including the MR Classification System, many modern, high-quality Level 1 MRI safety films are available.

    All of this information has been wonderful for our use in training employees and facilitiy to use mri scanners safely.
