If you work as an MRI tech aide, MRI assistant, or imaging assistant, there are two credentials you can earn. ARRT’s new Imaging Assistant, Magnetic Resonance (I.A.(MR)) certifies the support role you already do. A technologist registry, ARMRIT or ARRT (MR), qualifies you to run the scanner. They take different amounts of work and lead to different jobs, and nothing stops you from doing the first on the way to the second.
Hospitals and imaging centers use different names for the same seat: MRI aide, MRI tech aide, imaging assistant, MRI assistant. If you screen patients, turn rooms, and stand next to the console, this page is written for you.

Who can apply for the I.A.(MR)
According to ARRT’s I.A.(MR) requirements, you must be at least 18 with a high school diploma or GED, meet ARRT’s ethics requirements, complete the structured education and clinical competencies within the 24 months before you apply, and have your work verified by an ARRT-registered technologist. Clinical competencies have to be complete before you apply for the exam.
The credential covers MR Level 2 safety, patient care, patient positioning, workflow support, and assisting with contrast administration under supervision and facility policy. ARRT is explicit that imaging assistants do not perform imaging or scanning.
Key Takeaway
The assistant credential puts a certification behind the job you have. The technologist registry changes the job. If the console is where you want to be, the I.A.(MR) is a step you can take, not the destination.
Which path fits you
- You want to stay in the assistant role with a certification behind it. The I.A.(MR) is built for that.
- You want to become the technologist and you do not hold an imaging credential. An ARMRIT-accredited MRI program is the direct route. The rest of this page is about doing it from the aide seat.
- You already hold an ARRT credential in another modality. MRI is a post-primary credential for you. See the ARRT MRI cross-training program.
MRI tech assistant programs: what is out there
Search for an MRI tech assistant program and you will find three kinds of offering.
- Short assistant courses. Online, self-paced courses built around the I.A.(MR) content outline. Many carry CE credits toward the 32 you need; confirm the provider is an ARRT-recognized CE approver. Clinical competencies are separate and happen at your workplace.
- Community college assistant tracks. A small number of colleges list an MR imaging assistant track.
- MRI technologist programs. These prepare you for a technologist registry. This is the only kind that ends with you qualified to scan.
If you already hold the aide job, the third kind is the one that changes your pay and your role. The rest of this page covers how aides do it without leaving the department they work in.
Most aides who become technologists train where they already work
Among students who enrolled at Tesla MR through our current application (April to September 2026), more than half are doing their clinical training at the imaging site where they already work, and about one in four held an MRI aide or MRI assistant title when they applied. MRI aides enroll at a higher rate than any other group of applicants, because the hardest part of any MRI program is already solved for them: they have a scanner, a department that knows them, and technologists who can mentor them.
Your employer is agreeing to three things.
- A site agreement between the facility and Tesla MR.
- A mentor: a technologist registered in MRI through ARRT or ARMRIT who will supervise your hours.
- Scanner time: at least 16 on-the-job training hours a week once clinicals start.
Students who train at their own workplace receive a $500 clinical-site credit after their first logged training hour. Many employers also reimburse tuition for staff they are growing into technologists: about a third of our enrolled students have an employer paying or reimbursing part of the cost. The full walk-through, including how to raise it with your manager, is in Can I do MRI clinicals at my current imaging center?. If you are a manager reading this, the employer view is in training MRI technologists in-house.
What already transfers, and what is left to learn
Transfers from the aide role: Zone discipline and safety screening, claustrophobia coaching, stretcher and wheelchair transfers, RIS and EHR navigation, and the rhythm of a list that is running behind. Career changers spend their first clinical month learning exactly these things.
Still to learn: pulse sequence selection, parameter changes, artifact troubleshooting, contrast screening and reaction response, and the responsibility for who enters Zone III and Zone IV. That is what the coursework, the simulator, and your mentor are for.
Tesla MR’s published time commitment, from admissions requirements, is about 5 hours a week in Phase 1, 10 hours in Phase 2, and 20 or more in Phase 3.
Already scanning without a registry?
Some departments have staff who were trained on the job and scan without a technologist credential. If that is you, the registry is what makes your experience portable: ACR MRI accreditation and most employers name ARRT or ARMRIT registered technologists, so the credential is what a new employer, or your current one at its next accreditation cycle, will ask for.
An ARMRIT-accredited program is the shortest documented route: at least 1,000 MRI clinical hours, logged at your own site if your employer hosts you, then the ARMRIT exam (registry review and free practice questions). ARMRIT’s other pathways are built on work experience alone and require 2,000 or more documented hours. For how employers treat the two registries, see ARRT vs ARMRIT: who hospitals hire and the full ARRT vs ARMRIT comparison.
Time, cost, and pay
Tesla MR is ARMRIT-accredited and does not require X-ray. Tuition is $11,500 paid upfront, $12,500 quarterly, or $13,400 monthly, with a $2,000 deposit. Tesla MR is not a Title IV school, so FAFSA and federal loans do not apply, and it is not GI Bill or VR&E approved. Details are on pricing.
MRI technologists had a national median wage of $95,480 in BLS’s May 2025 data, and BLS projects 8% employment growth for the occupation from 2025 to 2035. State and metro figures are on the MRI salary map. The raise comes when you are credentialed and hired as a technologist, which is your employer’s decision. Training at the site where you want that job is the best way to be the obvious candidate.

Frequently Asked Questions
Yes. ARRT's Imaging Assistant, Magnetic Resonance credential, written I.A.(MR), is the first national certification for the aide and assistant role. Its first exam window is October 15 to November 30, 2026. It certifies the support role. It does not let you operate the scanner. To scan, you need a technologist registry: ARMRIT or ARRT (MR).
A technologist registry. The two that employers and ACR accreditation name are ARRT (MR) and ARMRIT. ARMRIT is MRI-only and does not require an X-ray credential first. ARRT (MR) is most often earned as a post-primary credential after radiography.
The assistant credential has no set program length. ARRT requires 32 continuing education credits earned within 24 months, plus documented clinical competencies, before you apply. The technologist path through an ARMRIT-accredited program takes 12 to 18 months and at least 1,000 documented MRI clinical hours.
Yes. The ARMRIT pathway is MRI-only. Tesla MR Institute's program is ARMRIT-accredited, takes 12 to 18 months, and does not require a radiography credential or a college degree.
Yes, if your employer agrees to host you. Tesla MR needs a site agreement, a mentor who is ARRT or ARMRIT registered in MRI, and scanner time for you. Students who train at their own workplace receive a $500 clinical-site credit after their first logged training hour.
Yes. Coursework is online, about 5 hours a week in Phase 1 and 10 in Phase 2. Clinical training needs at least 16 on-the-job hours a week once it starts, and Phase 3 is built around 20 or more. Training at your own site is what makes that schedule workable for most aides.
BLS has no separate category for MRI aides; job postings commonly fall between $15 and $25 an hour. MRI technologists had a national median wage of $95,480 in BLS's May 2025 data (SOC 29-2035), about $45.91 an hour.
No school can promise that, and Tesla MR does not. Hiring is your employer's decision. Finishing your clinical hours at a site that already knows your work is the strongest position to be in when a technologist seat opens.
