Synopsis
We propose an educational magnetic resonance (MR) safety course for
instructing medical students world-wide about basic MR and patient-related
safety. The MR safety course material can be implemented as a traditional
didactic or interactive lecture in combination with hands-on safety
demonstrations and will prepare medical students for patient screening and
safety consultations when ordering MR studies. This course can be implemented
globally by various medical school programs to ensure consistent quality of teaching
materials and MR safety standards.Purpose
This
educational exhibit outlines the design of a globally applicable educational
MR safety module with a concise multiple choice exam for instructing medical
students about basic MR and patient related safety. The MR safety course can be
implemented as a traditional didactic lecture, interactive, or self-administered
online. The goal of the course is to make sure that medical students worldwide
get a basic understanding of MR principles and safety considerations. It
prepares the medical students for optimal ordering of MR studies while
emphasizing patient screening and safety. A standardized multiple-choice exam,
accessible through the internet and the program ExamWeb (Exam Web, LLC; Newport
Beach, CA) at the end of the course documents the proficiency of the medical
students. The course covers low field MRI systems in developing countries as
well as state-of-the-art ultra high field MRI systems. It can be used
universally by all medical school programs and will help to ensure consistent
quality of teaching materials and MR safety standards.
Outline of Content
1.) Course description and examples of implementation
2.) Importance of MR safety for physicians
3.) MR principles and magnetic fields
- Static magnetic fields (B0)
- Radiofrequency field (B1)
- Gradient fields (Gx, Gy, Gz)
4.) Effects of magnetic fields in an MR suite
- Attractive forces on ferromagnetic objects
- Projectile effects
- Thermal effects
- Peripheral nerve stimulation
5.) Types of MR systems
6.) Fringe fields and 5 Gauss line
7.) MR screening procedures
- Implanted devices (e.g. pacemakers, hearing aids, surgical implants)
- Pregnancy
- MR contrast agent reactions and renal insufficiency
8.) Emergency procedures in an MR suite
Summary
This educational exhibit will provide a comprehensive overview on the implementation of an internationally applicable MR safety course for medical students. Education in MR safety for medical students will enable these future physicians to optimize requests for MR studies by increasing their understanding of patient screening and safety procedures.
