Standardized MR terminology and reporting of implants and devices as recommended by the American College of Radiology Subcommittee on MR Safety.

Considerable confusion exists among the magnetic resonance (MR) imaging user community as to how to determine whether a patient with a metal implanted device can be safely imaged in an MR imaging unit. Although there has been progress by the device manufacturers in specifying device behavior in a magnetic field, and some MR imaging manufacturers provide maps of the "spatial gradients," there remains significant confusion because of the lack of standardized terminology and reporting guidelines. The American College of Radiology, through its Subcommittee on MR Safety, has proposed standardized terminology that will contribute to greater safety and understanding for screening metal implants and/or devices prior to MR imaging.

ACR guidance document on MR safe practices: 2013.

Because there are many potential risks in the MR environment and reports of adverse incidents involving patients, equipment and personnel, the need for a guidance document on MR safe practices emerged. Initially published in 2002, the ACR MR Safe Practices Guidelines established de facto industry standards for safe and responsible practices in clinical and research MR environments. As the MR industry changes the document is reviewed, modified and updated. The most recent version will reflect these changes.
