Test Your MRI Safety Knowledge
Before your next scan, five minutes of self-testing beats an hour of worry — and teaches the rules the screening form is actually asking about.
This self-quiz covers the MRI safety essentials — implants, metal, makeup, tattoos, and the always-on magnet — with explanations for every answer. Score yourself honestly: anything under four of five sends you back to the safety basics, which are all covered across this library's guides.
Question 1: Which of these is safe to bring into the MRI room?
A) Your phone B) A titanium hip replacement (documented) C) Your credit cards D) A pair of scissors
Answer: B. Documented, verified implants are the exception the screening exists for. Everything else on the list is a projectile, a data-destroyer, or both. The magnet is always on — even at 3 a.m., even when nobody is scanning — and it does not negotiate. Details: implant safety and preparation.
Question 2: A friend says they were told to skip makeup before an MRI. True or false?
Answer: True (mostly). Some cosmetics — especially mascara, eyeshadow, and powders with metallic pigments — contain fine metal particles that can heat or distort facial images. Everyday light makeup is usually fine for body scans; the caution targets head and face imaging. The deeper lesson: seemingly innocent products carry metal where you least expect it — the screening form's "have you" list is longer than intuition suggests. Details: prep.
Question 3: Your grandfather has an old pacemaker from 1998 and needs a brain MRI. Automatic no?
Answer: Not automatic — but complicated. Devices are classified MRI-conditional, MRI-unsafe, or non-conditional; some pre-2000 devices are contraindicated, while others are scannable under protocol with cardiology management. The correct move is never "no" by default and never "yes" by assumption — it is model verification by the device team, then a planned scan with device programming before and after. Details: pacemaker MRI.
Question 4: You feel a warm flush and metallic taste during the contrast injection. Emergency?
Answer: Almost certainly no — it is the expected signature. Gadolinium's classic sensations are a brief warm wave (often strongest in the pelvis), a cool arm, and a fleeting metallic taste, all fading within a minute or two. What IS an emergency: pain, burning, or swelling at the IV site (extravasation), or hives, throat tightness, or breathing trouble (reaction). Knowing the difference between "expected" and "emergency" is precisely what turns injection anxiety into injection tolerance. Details: contrast sensations and contrast allergy.
Question 5: The technologist leaves the room during your scan. Why?
A) The magnet is dangerous to them B) They are watching from the control room, monitoring you continuously C) Both D) Neither
Answer: C. The field is a cumulative occupational hazard — technologists limit their daily exposure via distance and shielding, precisely because they work beside it all day. And they never actually leave: a window, a camera, an intercom, and your alert ball keep you continuously monitored. The empty room is an illusion; the attention never was. Details: radiologist vs technologist.
Your score, interpreted
5/5: You know more MRI safety than most first-year residents — walk in confident. 4/5: Solid; review the one you missed. 3 or below: Read the linked guides before scan day — every single rule above traces to a real event, and the screening form assumes you know them. The good news: everything on this quiz takes twenty minutes to learn, and it stays learned forever. The magnet rewards the prepared.

Is this quiz medically accurate?
Every answer reflects current MRI safety practice and the guidelines cited in this library's sources.
Can I share this quiz with family before their scans?
Please do — pre-scan safety knowledge is the cheapest anxiety-reducer in imaging.
What is the single most important MRI safety rule?
Honest screening: every implant, every device, every metal item, declared without guessing or hiding.
Does the magnet ever turn off?
Effectively never — even overnight and weekends. Treat every inch of every MRI suite as live, always.
Are the quiz answers different for open MRI?
No — the field physics are identical; only the enclosure changes.
Where do I learn more after the quiz?
Every answer links a full guide — the library cross-references itself from here.
