Contents:

Base Module inactive MRI: general hazards of a switched off MRI system (required)

• superconducting Magnet (Attraction forces)
• Contraindications arising from ther static magnetic field
• compatibility of equipment
• liquid Helium (Quench)
• Emergency procedures

Base Module active MRI: hazards caused by an MRI during operation (required)

• switched imaging gradients
  • noise
  • induction and peripheral nerve stimulation
  • Vibrations of non-magnetic but conductive implants
• High Power Radio-frequency transmitter
  • Heating effect on tissue
  • wires acting as resonant antenna
  • tattoos, piercings, etc.

Add-on Module: S1 GenTSV for small animal MRI  (optional, required for access to S1 lab)

• Laws and regulations
• Definitions of Risk/safety level according to GenTSV and BioStoffV
• S1 documentation ahead of experiments
• risk mitigation by standard S1 lab rules

Add-on Module: small animal MRI  (optional, required for conducting experiments)

• Requirements
