  1. MRI Safety Jeopardy* Because when you think MRI safety, think * Jeopardy is a trademark of Sony Digital Pictures, Inc.

  2. Forces – 10 points This is the part of the MRI system that generates the magnetic field which exerts forces on ferromagnetic materials that get near. Because when you think MRI safety, think

  3. Forces – 20 points These are the two directional physical forces that act on ferromagnetic materials in a magnetic field. Because when you think MRI safety, think

  4. Forces – 30 points For rotation / torque, this is the location where the ‘twisting’ forces are strongest inside the MRI room. Because when you think MRI safety, think

  5. Forces – 40 points For attractive forces, it is the location inside the magnet room where attractive effects go to zero. Because when you think MRI safety, think

  6. Forces – 50 points The physical force resisting movement that can be generated in a non-ferromagnetic metal when in a powerful magnetic field. Because when you think MRI safety, think

  7. Projectiles – 10 points This type of accident is the most frequent in MRI. Within the VA system, they cost an average of $43,172 for each reported accident. Because when you think MRI safety, think

  8. Projectiles – 20 points Though often referred to as if it were one metal, this is actually a ‘family’ of steel alloys that are resistant to corrosion, some of which are ferromagnetic. Because when you think MRI safety, think

  9. Projectiles – 30 points True / False: Translational (projectile) forces are only applied to objects outside a person’s body? Because when you think MRI safety, think

  10. Projectiles – 40 points This is the name for the ACR Zone in which projectile risks are the greatest. Because when you think MRI safety, think

  11. Projectiles – 50 points This is the new type of ‘MRI metal detector’ that is recommended by the ACR, and cited by JCAHO, as a means of helping to prevent projectile accidents. Because when you think MRI safety, think

  12. Potpourri – 10 points This is the new designation for metal-containing implants or devices, instead of the old ‘MR Safe’, used to identify safe operating parameters. Because when you think MRI safety, think

  13. Potpourri – 20 points For some MR exams, this can be equal to 120 decibels, equivalent to a jet engine. Because when you think MRI safety, think

  14. Potpourri – 30 points True/False: A grey or silver colored portable oxygen cylinder means that it is non-ferromagnetic and is not a projectile risk in the MRI room? Because when you think MRI safety, think

  15. Potpourri – 40 points The new ‘MR Safe’ designation requires that the object be, 1. Non-metallic, 2. Not electrically conductive and, 3. ________. Because when you think MRI safety, think

  16. Potpourri – 50 points This term describes the rate at which the static magnetic field strength changes as you move towards or away from the MR gantry. Because when you think MRI safety, think

  17. Heating – 10 points These injuries can result from contact with the bore wall, proximity to RF coils, or focal heating of electrically-conductive materials in the bore with the patient. Because when you think MRI safety, think

  18. Heating – 20 points Because loops can create antennae for focal RF heating, it is important to place these in straight runs out of the bore, insulated from contact with the patient, when used. Because when you think MRI safety, think

  19. Heating – 30 points MRI manufacturers all recommend 1/4 – inch to 1/2 – inch minimum of this between patients and the RF coils to avoid focal heating. Because when you think MRI safety, think

  20. Heating – 40 points These wires inside the bodies of some patients may experience even greater heating if they’re disconnected from the pulse generator to which they’re originally attached. Because when you think MRI safety, think

  21. Heating – 50 points These types of burns are possible in MRI because body tissue is mostly water and is, itself, an electrical conductor. Because when you think MRI safety, think

  22. Screening – 10 points In addition to the MR patient, these people should be screened for contraindications before entering the 5-gauss zone. Because when you think MRI safety, think

  23. Screening – 20 points This is one of two organizations that have standardized MR screening forms available for free download, both in English and Spanish. Because when you think MRI safety, think

  24. Screening – 30 points True/False: A patient that reports having received an MR previously does not require full screening? Because when you think MRI safety, think

  25. Screening – 40 points Along with “clinical screening,” this is the other half of pre-MRI screening needed for a comprehensive screen. Because when you think MRI safety, think

  26. Screening – 50 points This disease, associated with Gadolinium and impaired kidney function, has all but been eradicated by improved screening and safer use of Gadolinium-based agents. Because when you think MRI safety, think
