The ACR has defined different levels of MR imaging personnel as follows (5): (a) level 1
MR imaging personnel—those who have passed minimal safety educational efforts to ensure their
own safety as they work within zone III; (b) level 2 MR imaging personnel—those who have been
more extensively trained and educated in the broader aspects of MR imaging safety issues; and
(c) non–MR imaging personnel—all those not having successfully complied with MR imaging
safety instruction. This category includes patients.
