Introduction

The MR Safety Guide contains information applicable to several system configurations. A topic heading, a note, or other wording indicates information that is applicable to a specific system configuration.

This section focuses on the visible and invisible sources of hazard and concern in the magnetic resonance (MR) imaging environment and emphasizes the need to work safely. To ensure safe operation of your scanner, you must understand several components of your imaging system. This chapter provides brief guidelines for working in a magnetic field, key concepts regarding the magnet, quench, radio frequency (RF), laser light, metal sliver, acoustic, peripheral nerve stimulation (PNS), and equipment hazards. It contains the step-by-step instructions to help you learn how to:

• Eliminate Magnet Hazards
• Respond to Emergencies
• Check the Cryogen Levels
• Handle Contact with Liquid Cryogens
