Best Online CE Courses for Nuclear Medicine Technologists in 2026
Keeping your ARRT or NMTCB credentials current means completing 24 Category A continuing education credits every two years — a requirement that holds regardless of how busy your clinical schedule is. The good news is that online CE platforms have matured considerably, and you no longer need to attend a conference in another city or pay premium prices to satisfy your biennium requirements.
This guide focuses specifically on platforms that serve nuclear medicine technologists (NMTs). Not all CE platforms carry meaningful nuclear medicine content, so the four reviewed here were selected based on their NMT-relevant course catalogs, accreditation status, and overall value. Whether you prioritize depth of nuclear medicine content, the lowest possible cost, or a mix of both, one of these platforms likely fits your workflow.
What Nuclear Medicine Technologists Need from a CE Platform
Before diving into specific platforms, it’s worth clarifying the requirement landscape. ARRT-certified NMTs need 24 CE credits per biennium, all of which must be Category A or Category A+. NMTCB-certified technologists (CNMT holders) have the same 24-credit biennium requirement, and those holding the NMTCB(CT) credential must ensure at least 12 of those 24 credits are CT-specific.
In addition to the standard biennium cycle, ARRT now requires a Continuing Qualifications Requirement (CQR) every 10 years — a structured self-assessment that may require additional coursework. Not all CE platforms are coded for CQR, so that distinction matters if you’re in a CQR year.
With those parameters in mind, here is how the leading platforms stack up.
Medality (formerly MRI Online)
Medality has positioned itself as a premium clinical education platform, originally built around MRI and radiology but now expanding into nuclear medicine. The nuclear medicine catalog includes case-based learning using actual DICOM files alongside video-based instruction — a format that appeals to technologists who learn best from clinical examples rather than pure text.
The platform’s Nuclear Medicine Fundamentals Level 1 course offers 7.5 CME hours, 111 videos, 59 DICOM case files, and approximately 12 hours of material. This depth is unusual for an online CE platform and more closely resembles a structured fellowship module than a traditional CE activity.
Pricing: Medality operates on a subscription model. A Standard annual plan runs $1,200/year; a Premium annual plan costs $1,499/year; and the Ultimate Learning Pass (which includes 19 fellowship certificate programs) is priced at $4,999/year. A 7-day free trial is available, and group discounts of 50% or more apply for teams of five or more.
Best for: Technologists who want genuine clinical depth and are comfortable with a higher price point, particularly those who also want to build skills in MRI or PET/CT alongside their nuclear medicine CE.
Accreditation: CME credits are offered through ACCME accreditation, which is accepted by ARRT.

RADUNITS
RADUNITS is built with one clear objective: deliver all 24 Category A credits a technologist needs for their biennium renewal, plus a meaningful portion of CQR credits, for a flat $49 per course. There are no subscriptions, no upsells, and no fine print — you pay once and earn your full complement of credits from a single course.
The platform’s course catalog covers the range of imaging modalities relevant to radiologic technologists, with content relevant to NMTs in areas such as emission tomography, image production, and patient care. All courses are approved for ARRT Category A credit and include CQR coding where applicable.
Pricing: $49 per course. No annual subscription required. Each course delivers the full 24 Category A credits.
Best for: Cost-conscious technologists who want to satisfy their entire biennium requirement in a single transaction. Also well-suited for technologists who need CQR credits alongside their standard CE.
Accreditation: ARRT Category A approved. Credits accepted for ARRT biennium renewal and CQR.
Check pricing and course options at RADUNITS — at $49 for a full biennium cycle, this is among the most cost-effective legitimate options available.
MTMI (Medical Technology Management Institute)
MTMI occupies a different niche than the previous two platforms. Rather than providing self-paced online reading modules, MTMI delivers live webinars, in-person workshops, and self-paced courses that lean heavily on clinical application and hands-on physics knowledge. For nuclear medicine technologists, MTMI’s standout offering is the Hands-On Nuclear Medicine Physics Workshop, which delivers 14.5 CE credits (plus 12.5 CAMPEP credits) in an intensive in-person format.
MTMI also offers live webinars on nuclear medicine-specific topics, a Nuclear Medicine Update course offering 6 CE credits, and a PACS course covering 2 CE credits that is relevant to most imaging modalities. For technologists who also work in CT — common in facilities with SPECT/CT or PET/CT systems — MTMI’s CT Training Course for Technologists delivers 40.75 CE credits.
Pricing: MTMI’s pricing is course-specific and not always listed publicly; prospective attendees are encouraged to contact MTMI directly or check their catalog for current session pricing. In-person workshops carry higher fees commensurate with the hands-on format.
Best for: Technologists who want deep, application-focused nuclear medicine physics education or who benefit from live instruction rather than self-paced modules. Particularly valuable if your facility runs a SPECT/CT system and you want physics-grounded training.
Accreditation: ARRT Category A CE, CAMPEP-approved credits for medical physicists.

eRadImaging
eRadImaging is the value leader in this comparison. An annual membership costs $54.95 and provides unlimited access to more than 100 ASRT-approved Category A CE credits. The platform has served the imaging community since the early 2000s and maintains a catalog that spans every major modality.
For nuclear medicine technologists specifically, eRadImaging carries courses covering emission tomography, PET/CT imaging applications, nuclear imaging in GI disorders, thyroid nodule evaluation, and radiation safety — all relevant to ARRT biennium requirements. The format is primarily reading-based (PDF articles with post-tests), which suits technologists who prefer to study at their own pace without video.
Pricing: $54.95/year for unlimited access to 100+ Category A credits. No additional per-course fees. Group rates available for employers.
Best for: High-value access for technologists who want maximum flexibility at minimum cost. Ideal if you need CE across multiple modalities (e.g., you also hold CT or radiography credentials) and want one low annual fee to cover all of them.
Accreditation: ASRT-approved (an ARRT-recognized RCEEM), accepted for ARRT biennium renewal and NMTCB renewal.
Check pricing and course catalog at eRadImaging — the annual flat-fee model is hard to beat for technologists holding credentials in more than one discipline.
Platform Comparison Table
| Platform | Annual Cost | NMT-Specific Content | CE Credits Included | Format | Best For |
|---|---|---|---|---|---|

Which Platform Is Right for You?
If budget is the primary concern, eRadImaging at $54.95/year and RADUNITS at $49/course represent the best cost-per-credit options on the market. eRadImaging wins on annual value if you hold multiple ARRT credentials; RADUNITS wins if you want a single clean transaction with CQR coverage.
If you want clinical depth — the kind of case-based learning that translates directly to better patient care — Medality is in a different category entirely. The price reflects that, but the learning experience is qualitatively different from a reading-based module.
If you or your department benefit from live instruction and hands-on physics education, MTMI fills a gap the other platforms cannot. Their nuclear medicine physics workshop in particular has no direct equivalent online.
One practical note: nothing prevents you from combining platforms. Many technologists complete their biennium CE through a lower-cost platform like eRadImaging or RADUNITS, then use Medality for advanced clinical training or MTMI for physics workshops when professional development budgets allow.
Conclusion
Online CE for nuclear medicine technologists has never been more accessible or more affordable. The four platforms reviewed here cover every realistic use case, from the technologist who wants to spend under $50 every two years to the one who wants immersive, case-based clinical training throughout the year.
Start by reviewing your specific requirements: check whether your ARRT credentials require CQR coursework in the current cycle, confirm whether your NMTCB(CT) credential requires CT-specific credits, and verify your state’s licensing board requirements if you practice in a state with its own CE mandates (Florida, for example, has additional requirements).
Once you know what you need, the platforms above each offer a clear value proposition. Do not let your credentials lapse when the cost of staying current is this low.
