2. Entering – 10 points True / False: MRI doesn’t use ionizing radiation (like X-ray) so there’s no need to control who gets in to the MRI room. Because when you think MRI safety, think

3. Entering – 20 points True / False: Like X-rays or CT scanners, the risks are only present when they’re ‘taking the picture’, otherwise it’s safe to enter. Because when you think MRI safety, think

4. Entering – 30 points If you’ve been allowed into the MRI department, that does / does not mean that it’s always safe to go into the room with the MRI scanner. Because when you think MRI safety, think

5. Entering – 40 points True / False: For MRI safety, it is only important to control access to the MRI room, itself, because there can’t be any magnetic field hazards outside the MRI room. Because when you think MRI safety, think

6. Entering – 50 points In case of emergency, police, firefighters or other emergency response personnel should be ____________ entrance the MRI suite as they wish. Because when you think MRI safety, think

7. Like a compass needle, unrestrained (ferro)magnetic materials will tend to _________ to align with the magnetic field. Magnets – 10 points Because when you think MRI safety, think

8. If you move two ‘fridge door’ type magnets together, there will be no interaction until you get them fairly close and then they will ________ each other with surprising speed. Magnets – 20 points Because when you think MRI safety, think

9. We live fully enveloped in the _______ magnetic field, which averages about ½ gauss (a measure of magnetic field strength). Magnets – 30 points Because when you think MRI safety, think

10. Magnets – 40 points Magnetic energy, or flux, flows from one ______ of the magnet to the other. Because when you think MRI safety, think

11. Magnets – 50 points Because when you think MRI safety, think The magnets that stick to your refrigerator door are ‘permanent’ magnets. ________ is the kind of magnet used in doughnut-shaped MRI scanners.

12. Potpourri – 10 points True / False: Magnetic energies have not been shown to have any long-term health effects. 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: It doesn’t matter how you position you body (as long as the part being imaged is in the right location). Because when you think MRI safety, think

15. Potpourri – 40 points True / False: MRI magnetic fields are strong, but it would take a fairly big magnetically-attracted object to hurt someone in the MRI room. Because when you think MRI safety, think

16. Potpourri – 50 points “Airport style” ___________ used for security screenings have been found specifically recommended against because they alarm on aluminum, brass, and other non-magnetic metals. Because when you think MRI safety, think

17. Metal – 10 points True / False: All types of metal are equally hazardous in the MRI room. Because when you think MRI safety, think

18. Metal – 20 points ________ is a lightweight metal often used to make tools or instruments for use near MRI machines because it is a non-magnetic material. Because when you think MRI safety, think

19. Metal – 30 points True / False: Because MRI’s have been around for 30 years, all metals used to make medical implants today are non-magnetic. Because when you think MRI safety, think

20. Metal – 40 points Metals that are attracted to a magnetic field under normal conditions are called _______ metals. Because when you think MRI safety, think

21. Metal – 50 points ___________, though often referred to as if it was a specific metal, is actually a group of metals that were developed with specific corrosion resistance. Because when you think MRI safety, think

22. Screening – 10 points True / False: Even if I’ve had an MRI before, I’ll still have to go through the full screening process again for my next MRI. Because when you think MRI safety, think

23. Screening – 20 points Because when you think MRI safety, think The first of the two general types of pre-MRI screening is called ________ and seeks to make sure that the patient has no implants or physical conditions that would be dangerous for the prescribed MRI exam.

24. Screening – 30 points After the clinical screening, MRI providers conduct a ________ screen to make sure that nothing hazardous is brought or carried into the MRI. Because when you think MRI safety, think

25. Screening – 40 points Though there’s a version of this type of implant currently under FDA review for MRI safety, these are perhaps the best known contraindicated (for MRI) active medical implant device. Because when you think MRI safety, think

26. Screening – 50 points If your MRI exam calls for contrast ‘dye,’ you will likely be screened for function of this organ, which is primarily responsible for removing the contrast agent from your body after the exam. Because when you think MRI safety, think
