MRI technologist screening questions: ARRT or ARMRIT, state licenses, MR safety and scan depth

MRI technologist screening questions need to check two things that general radiology screens often blur: the MRI-specific credential (ARRT in MR or ARMRIT, not just a radiography R.T.) and the candidate's safety habits in a room where a ferromagnetic object becomes a projectile and an unscreened implant can injure a patient. After that, test scan depth: which body parts and protocols they run alone, which scanners they know, and how they handle contrast, claustrophobic patients and add-ons at the end of a long list.

This page goes deeper on MRI than the general radiology technologist screening questions, which cover x-ray, CT and mammography. For cross-trained sonographers moving into MRI, compare with the ultrasound technician screening questions.

Which MRI job

Credentials and state licenses

ARRT in magnetic resonance imaging

ARRT certifies MRI technologists through two routes. The primary eligibility pathway is for graduates of an MRI educational program. The postprimary pathway is for technologists already ARRT certified and registered in a supporting discipline (and in some cases those certified by NMTCB or ARDMS), who also meet structured education and clinical experience requirements. Both end with the same MRI exam. A radiographer who has "done some MRI" without passing that exam does not hold the MRI credential.

ARMRIT

The American Registry of Magnetic Resonance Imaging Technologists is an MRI-only certifying registry. It says certification is open to technologists who have documented MR clinical experience and/or formal education from schools dedicated to MRI technologists, and that it requires MRI clinical experience and competency for eligibility. Some employers accept ARMRIT, some require ARRT; ask the client before you screen.

ARRT Imaging Assistant, Magnetic Resonance

ARRT also offers an Imaging Assistant, Magnetic Resonance credential, I.A.(MR), for people who help registered technologists with MR safety, patient care, positioning and contrast administration. ARRT states that imaging assistants do not perform imaging or scanning. If a resume lists I.A.(MR), screen for an assistant role, not a technologist role.

State license example: Oregon

Oregon's Board of Medical Imaging rule OAR 337-010-0013 requires an individual who operates MRI equipment to submit evidence of current MRI credentialing from ARRT or ARMRIT, and the Board verifies status through those organizations' directories. Other states set their own rules, and not every state licenses MRI separately. Look up the job state before you promise a start date, and allow time for the license if one is needed.

Knockout questions

MR safety questions

The ACR Manual on MR Safety (2026 edition) is the reference many sites build their policies on, including a four-zone access model and levels of trained MR personnel. Listen for whether the candidate thinks in those terms without being prompted.

1. "A patient's screening form says they have a heart device, but they don't know which one. What happens next?"
   • Strong answer: does not scan until the exact device is identified (implant card, records, manufacturer), checks its MR conditions, involves the radiologist and, for active devices, the cardiology or device team the site's policy names; reschedules if the device cannot be identified.
   • Red flags: "Most new pacemakers are fine, so we scan."
2. "Who is allowed into the scanner room at your last site, and how did you control it?"
   • Strong answer: describes controlled access, screening of every person including staff and family, and stopping a code team or housekeeping from walking in with equipment.
   • Red flags: no clear answer about who screens non-MR staff.
3. "Tell me about a near miss you saw or stopped."
   • Strong answer: a specific event (oxygen tank, wheelchair, a forgotten hair clip or patch), what they did and how it was reported.
   • Red flags: claims never to have seen one in years of scanning, or treats incident reports as blame.
4. "How do you prevent burns?"
   • Strong answer: removes non-essential conductive items, avoids skin-to-skin loops, uses padding, routes cables properly, checks the patient during the scan and stops for heating complaints.
   • Red flags: no mention of positioning or cables.

Scan depth and patient care

• "Which exams do you run without help?" Strong: brain, spine and joints at minimum, with specifics for contrast studies, MRA, abdomen, prostate, breast or cardiac.
• "A knee study shows motion on two sequences. What do you change?" Strong: talks to the patient, re-positions with better padding, adjusts parameters or uses motion-reduction sequences per protocol, and knows when to call the radiologist.
• "A patient panics halfway through a brain scan." Strong: stops, talks them out of the bore, offers options (prism glasses, music, feet-first if the protocol allows, a family member screened into the room), follows the site's sedation policy only with an order.
• "Walk me through a contrast study." Strong: checks the order and kidney-function policy, screens for prior reactions, IV access per state scope and site policy, timing, watches for reactions and knows where the emergency kit is.
• "How many patients did you scan in a typical shift?" Record the number as the candidate's own example; compare it with the client's schedule.

How MRI experience gets overstated

• Clinical rotations described as a staff job. Ask for employer names and dates.
• Assisting described as scanning. An I.A.(MR) or aide role is support work, not scanning.
• 3T experience that was occasional. Ask what share of their exams were at 3T.
• Cardiac or breast MRI that meant watching a senior tech. Ask which sequences they planned themselves.
• "Safety officer" that was an informal title. Ask what they trained, audited or wrote.

A 12-minute phone-screen flow

1. Minutes 0 to 2: setting, scanners, shift and call pattern, and whether the role is technologist or assistant.
2. Minutes 2 to 5: knockout questions 1 to 4; look up the credential while the candidate talks.
3. Minutes 5 to 9: the heart-device scenario and one more safety question.
4. Minutes 9 to 11: independent exam list and the claustrophobic-patient answer.
5. Minute 11 onward: the candidate's questions, license timing and next steps.

Ask about the ability to perform the job's physical tasks, such as transferring patients to the table, with or without accommodation, rather than about health conditions or implants of their own. A candidate's own MR screening belongs to the site's safety process after hire, not to the phone screen.

Scoring

In the submittal, record the credential and license numbers with expiry dates, scanners and field strengths, independent exam list and a one-line summary of the implant answer. A reference from a lead tech or radiologist is the best check of safety habits; the reference check template has questions you can adapt. For later rounds, see the interview guide for healthcare roles.
