Introduction to MRI Safety Webinar Replay

List at least one risk associated with each of the following:

• Static magnetic field
• Time-varying gradient magnetic fields
• Time-varying radio frequency magnetic fields
• Biologic effects
• Acoustic noise
• Quench
• MR Contrast media

Explain why there is little data related to pregnancy risks at higher field strengths

• A risk/benefit analysis for scanning pregnant patients
• Pregnant technologists and other healthcare practitioners

Additional Objectives

• Create a list of preventative actions for each of the risks associated with MRI
• Identify and define the four safety zones in the MR department
• Define a quench and provide the two types of quench initiation
• Give examples of screening questions used to clear patients for MR examination and scanning
• Explain MR personnel training levels and MRSO education and testing
