MRI Technologist Interview Questions
& Model Answers, 2026

Zone one is freely accessible public space, zone two is where patients are screened and supervised, zone three is restricted and physically controlled because the fringe field is a hazard, and zone four is the magnet room itself, which must be under the direct supervision of MR personnel at all times. Everyone entering zones three and four is screened, including staff, cleaners, engineers and emergency responders. Say plainly that the magnet is always on and that access control is a technologist's personal responsibility, not the department's paperwork.

Do not scan. Identify the device through the operative note, the implant card, the surgeon or the manufacturer, and check the labelling and the conditions — field strength, gradient slew rate, specific absorption rate limits, and any positioning restriction. If the device cannot be identified and cleared, escalate to the radiologist and the MR safety officer and consider an alternative modality or a radiograph to characterise it. An unverified implant is an unsafe implant.

T1 gives anatomy with fat bright and fluid dark, and is the post-contrast workhorse. T2 makes fluid and most pathology bright. FLAIR nulls cerebrospinal fluid so periventricular lesions stand out. STIR suppresses fat and is used for marrow oedema and musculoskeletal pathology, particularly where fat saturation is unreliable. Diffusion weighting with the ADC map identifies restricted diffusion, which is the basis of acute stroke imaging and helps characterise abscess and some tumours.

Order and indication, prior reaction history, pregnancy status, and renal function against the department's eGFR threshold, with attention to the agent class since group two macrocyclic agents carry a much lower nephrogenic systemic fibrosis risk than older linear agents. Confirm IV access, use the lowest diagnostic dose, document the agent, dose and lot, and observe the patient afterwards. Know the department's policy for dialysis patients.

Motion produces ghosting along the phase-encoding direction and is addressed by coaching, immobilisation, shorter sequences, triggering or swapping phase direction. Aliasing or wrap comes from a field of view smaller than the anatomy and is fixed by oversampling or a larger field. Susceptibility distortion near metal responds to a lower field strength option, higher bandwidth, gradient echo avoidance and metal artefact sequences. Chemical shift is corrected with higher bandwidth or fat suppression. Zipper artefact means radiofrequency leakage — check the door.

Explain the scan properly including the noise and duration, offer feet-first entry and prone positioning where the study permits, use a mirror or prism glasses, give the squeeze ball and answer it every time, keep talking between sequences, allow a companion in the room after screening them, use ventilation and lighting, and shorten the protocol to the essential sequences. If it still fails, arrange sedation or an open scanner rather than producing an unusable study.

A quench is the sudden boil-off of the cryogen and loss of superconductivity, venting helium that can displace oxygen in the room. Evacuate the patient and everyone else immediately, do not re-enter, prop the door if pressure prevents opening, activate the emergency plan and call the engineer, and treat the room as an asphyxiation hazard until it is cleared. Say that the emergency quench button is only pressed when a person is pinned to the magnet — never to remove an object.

A hairpin, an oxygen cylinder, a patient who forgot a pacemaker, a colleague who walked in unscreened: describe what happened, what you did, and whether you reported it. MR departments hire for candour about near misses, because the technologist who reports the small one prevents the fatal one.

Give the reason, how you communicated it to the patient and the referrer, who you escalated to, and what the alternative was. Say how you handled the pressure to proceed. The willingness to say no while offering a route forward is the single behaviour MR managers most want to see.

Describe the preparation, the practice run, the distraction and the sequence order you chose to get the essential images first. Then say when you concluded sedation was needed. Interviewers value a technologist who gets the diagnostic sequences before the patient's tolerance runs out.

Shortening a protocol without losing diagnostic value, reordering sequences, changing coil setup, or reducing changeover time between patients: give the before and after numbers and how you got the radiologist's agreement. Throughput improvements that keep quality are highly valued in MR because scanner time is the constraint.

Anchor on the modality-specific series: magnetic resonance imaging technologists have a BLS OEWS May 2025 median of $95,480 a year, about $45.90 an hour, with the top 10% above $127,670. That is an MRI-specific occupation code rather than a blended imaging figure, so it is a strong anchor. Then argue from experience, field strengths you have worked on, and whether you cover cardiac, breast or interventional MR.

Get the differentials as hourly figures and check whether they apply to the whole shift. MRI is increasingly run into evenings and weekends to maximise scanner utilisation, so the differential is a core part of the package rather than an occasional extra. Ask how many patients are booked per hour on those shifts and whether a second technologist is present, because lone working changes both safety and workload.

Advanced application training on cardiac, breast, prostate or spectroscopy, ARRT post-primary certification funding, MR safety officer training, continuing education and conference attendance, a defined call arrangement, and hearing protection and ergonomics provision. Advanced applications training is what moves you toward the upper end of the range within a couple of years.
