Program Summary

Applied Radiology and William Faulkner & Associates are pleased to introduce “The Online Course for MR Safety Officers (MRSO) and MR Medical Directors (MRMD)”. This comprehensive program, focusing on MR Safety, covers many aspects relating to the safety practices of the Magnetic Resonance Imaging (MRI) environment. It is designed for those individuals who are either currently serving as their facility’s MRSO and/or MRMD, or those who are preparing to assume these responsibilities. The content of this course will be helpful for those preparing for the American Board of Magnetic Resonance Safety MRSO and MRMD examinations.

Over the past 30+ years, Magnetic Resonance Imaging (MRI) has become a major tool in diagnostic imaging. Advancements in the technology have resulted in faster imaging sequences and clinical systems with field strengths ranging from low field at .2T, to high field at 7T. With the increase in MRI utilization, the number of reported safety incidents has increased significantly. Accrediting entities such as American College of Radiology and The Joint Commission have increased their focus on MR Safety, requiring that an MRI environment be safe and staffed with knowledgeable individuals who are regularly trained, with the goal of avoiding safety-related incidents and injuries. Often, for many MRI departments, MR Safety Training is not regularly provided, nor closely monitored or enforced as a part of the routine clinical practice. Therefore, MR Safety training is both necessary and important, for radiologists, technologists, and anyone working in, or entering the MRI environment. Having trained individuals in the role of MR Medical Director and MR Safety Officer is essential to creating and maintaining a culture of safety in MRI.

In 2002 the ACR published the first guidance document on MR Safety known as the ACR Guidance Document for MR Safe Practices. This document has been updated several times and has become the “de facto industry standard”.

The content of The Online Course for MR Safety Officers and MR Medical Directors is based upon current FDA and ACR guidelines, including the ACR Guidance Document for MR Safe Practices, as well as those promulgated by industry regulatory bodies such as the International Electrotechnical Commission.

Successful completion of the program results in 10 hours of Continuing Medical Education credits and 10 hours of Category A credits.

* The Online Course for MR Safety Officers (MRSO) and MR Medical Directors (MRMD) is intended to be an online study course and is not considered to be a substitution for the MRSO/MRMD certification examination. Further, The Online Course is not affiliated with, nor endorsed by the American Board of Magnetic Resonance Safety. Participants must still schedule time to take the MRSO/MRMD certification exam when offered for full certification
