MRI Technologist interview questions and how to answer them

An MRI interview circles back to one idea: can this person keep the magnet room safe when everyone around them is in a hurry. Expect scenario questions about implants, code situations and patients who won't hold still, plus a few about the physics behind the images. Managers listen for whether you'd stop a scan when it's the right call, even when the schedule says keep going.

11 questions7 minute read

Part 1

1.Walk me through how you screen a patient before they enter the scanner room.

Why they ask

Screening is the core safety job in MRI, and a sloppy habit here is how people get hurt.

How to answer

  • Go through the written form with the patient out loud, not just collect it
  • Ask about pacemakers, neurostimulators, clips, metal work in the eyes and past surgeries
  • Have them change into gowns or scrubs and remove anything from pockets
  • Use a ferromagnetic detector where the suite has one, and escort them in yourself
  • Mention that you rescreen anyone who arrives from a floor with new devices or lines

2.A patient has an implant card for a device you've never seen. What do you do?

Why they ask

They want to hear that you look things up and escalate, rather than guess or cancel by reflex.

How to answer

  • Identify the exact make and model from the card or the surgical record
  • Check the manufacturer's MR conditions and a reference like MRIsafety.com
  • Confirm the scanner, coil and SAR limits you'd need to stay within
  • Loop in the radiologist or MR safety officer before scanning
  • Rebook with the right protocol if the conditions can't be met today

3.A code is called on a patient inside the scanner. What happens next?

Why they ask

The instinct to let the code team rush in is exactly what makes MRI codes dangerous.

How to answer

  • Stop the scan and get the patient out of the bore and out of the magnet room
  • Start CPR outside the room while the team arrives
  • Stand at the door and keep the code team and their equipment out
  • Know your site's plan and where the MR-conditional equipment is kept
4.When would you hit the quench button?

Why they ask

It's a real emergency tool, and they want to know you'd use it only when someone is pinned or a fire can't be handled otherwise.

How to answer

  • Explain that quenching ramps the field down and boils off helium fast
  • Use it only for a life-threatening situation like a person pinned by a metal object
  • Mention that a quench is costly and takes the scanner out of service
  • Say you'd follow the site policy and notify physics and service right away
5.How do you handle a patient who's claustrophobic and wants to stop halfway through?

Why they ask

Incomplete studies cost the department and the patient, and your bedside manner decides a lot of them.

How to answer

  • Prepare before the scan: explain the noise, the length and how to reach you
  • Use feet-first positioning, a mirror, music or a blanket when the protocol allows
  • Talk to them between sequences and tell them how long is left
  • Prioritize the key sequences so the radiologist gets what matters first
  • Know when to stop and ask the ordering doctor about sedation or an open scanner

Part 2

6.What do you check before giving gadolinium contrast?

Why they ask

Contrast safety is shared between you, the nurse and the radiologist, and they want to see your part of it.

How to answer

  • Kidney function, usually eGFR, per the department's policy
  • Prior reactions, allergies and whether premedication was ordered
  • Pregnancy and breastfeeding questions where the policy asks
  • IV site, gauge and the power injector settings for the protocol
  • What you'd watch for after injection and who you call if there's a reaction
7.Your images show a strong artifact. How do you figure out the cause?

Why they ask

MRI techs adjust sequences on the fly, and fixing artifacts is where you show you understand the physics.

How to answer

  • Name the artifact: motion, wrap, susceptibility, chemical shift or zipper
  • Match the fix: phase direction, field of view, saturation bands or a different sequence
  • Check the patient first for metal, breathing or a loose coil
  • Give a real example where you fixed it and the radiologist didn't need a repeat
8.A nurse brings an inpatient down with an IV pump and oxygen tank. What do you say?

Why they ask

You'll have to hold the line with colleagues who outrank you or are rushed, and they want to hear how you do it.

How to answer

  • Stop them at the zone boundary before anything crosses
  • Swap to MR-conditional oxygen and pumps, or run long IV lines through the waveguide
  • Rescreen the patient because they come with lines, leads and monitors
  • Stay calm and polite but don't bend on the rule
9.Tell me about a time you disagreed with an order or protocol.

Why they ask

Orders sometimes don't match the clinical question, and they want someone who raises it instead of scanning blindly.

How to answer

  • Describe the order and what didn't fit, like a non-contrast study for a tumor follow-up
  • Explain who you called, usually the radiologist, and what you said
  • Share the outcome and whether the order was changed
  • Show you did it without delaying the patient longer than needed
10.How do you keep an MRI schedule on track when studies run long?

Why they ask

Long protocols and add-ons make MRI schedules fragile, and managers care about throughput.

How to answer

  • Screen and change the next patient while the current one is scanning
  • Prep coils and the injector ahead of time
  • Tell waiting patients honestly about delays
  • Flag repeat problems like underbooked cardiac slots to the supervisor

Part 3

11.Why MRI rather than another modality?

Why they ask

They want to hear real interest, since MRI's physics and pace aren't for everyone.

How to answer

  • Name what draws you, like tuning sequences or seeing soft tissue detail
  • Mention a study you liked running, such as a knee, a spine or a breast exam
  • Show you know the downsides, like the safety burden and long studies
  • Say where you want to grow, for example cardiac or MR safety

Questions to ask them

Ask at least two. It shows you're picking them too.

  • Who is the MR safety officer here, and how are implant questions handled after hours?
  • Which scanners and field strengths will I work on, and who trains me on new protocols?
  • How are inpatient and ER add-ons fitted into the outpatient schedule?
  • What does orientation look like before I scan on my own?
  • How often do you run sedation or anesthesia cases, and who staffs them?
