Best CT Technologist CE Courses Online (ARRT Approved)
Staying current in computed tomography is not optional — it is a credentialing requirement. As a registered CT technologist, you need 24 Category A CE credits every two years to maintain your ARRT certification. With protocol complexity, dose optimization mandates, and AI-assisted reconstruction becoming the norm, those 24 credits should actually mean something.
This guide breaks down the top online CE providers for CT technologists, compares their catalogs, pricing, and approval status, and helps you make an efficient, cost-effective choice before your biennium deadline.
What “ARRT Approved” Actually Means for CE
The ARRT does not directly approve CE courses. Instead, it recognizes a list of Recognized Continuing Education Evaluation Mechanisms (RCEEMs) — most notably the American Society of Radiologic Technologists (ASRT) and the Medical Dosimetry Certification Board (MDCB). When a provider says their courses are “ARRT approved,” they mean the content has been approved by one of these accrediting bodies, making it eligible for Category A credit.
Before purchasing any course, confirm:
- The approving body (ASRT, MDCB, or equivalent RCEEM)
- Whether the course applies to CT-specific Structured Education (SE) requirements if you are cross-training
- Your state’s additional licensing requirements — some states add topic-specific mandates beyond ARRT’s biennial 24-credit baseline
You can verify any course at the ARRT’s CE search tool.
Top CT Technologist CE Providers Compared
| Provider | Format | CT-Specific Courses | Approval | Pricing Model | Best For |
|---|---|---|---|---|---|
| Medality | On-demand video | Yes (case-based) | CME/ABR MOC | Subscription | Physician-adjacent visual learning |
| MTMI | Live webinar, in-person, self-paced | Yes (CT bootcamp + CE) | ASRT Category A | Per-course or bundle | Cross-training, certification prep |
| ASRT | Online library | Yes (500+ courses) | ASRT Category A | Membership + per-course | Breadth across all modalities |
| eRadImaging | Online self-study | Yes (CT-focused modules) | ASRT Category A | Annual subscription | High-volume, affordable CE completion |
1. Medality (Formerly MRI Online)
Medality is best known in the radiology physician space, but its CME QBank and case-based content have growing appeal for technologists looking to understand the interpretive side of imaging. Their platform uses clinical questions to deliver credits — answering 200 unique questions earns the equivalent credit hours.
What it offers CT techs:
- Case-rich, image-heavy content covering CT pathology across all organ systems
- ABR MOC-style question bank useful for technologists pursuing advanced credentials
- On-demand format accessible 24/7
What to keep in mind:
- Primary audience is radiologists; some content exceeds the technologist scope
- Pricing is subscription-based — best value if you consume significant volume

2. MTMI (Medical Technology Management Institute)
MTMI is arguably the gold standard for CT cross-training and CE in the technologist community. Their flagship CT Training Course for Technologists provides 40.75 hours of ASRT Category A CE credit, including the 16 hours of Structured Education required by the ARRT for CT post-primary certification. Their 96% board pass rate reflects a curriculum built specifically around the ARRT CT Registry Examination content specifications.
What it offers CT techs:
- Three formats: in-person, live webinar, online self-paced (up to 6 months to complete)
- Covers CT physics, image quality, artifacts, dose, and anatomy across all major protocols
- ScanLabCT™ simulation software included for 3 months
- Optional clinical placement program for technologists meeting ARRT CT clinical hour requirements
- ASRT, ACCME, CAMPEP, and CBRN accredited
Pricing: Reduced pricing periodically offered; check site for current bundle deals.
Best for: Technologists pursuing ARRT CT certification or needing high-credit, registry-focused content.

3. ASRT (American Society of Radiologic Technologists)
The ASRT is both an accrediting body and a CE provider — which means its own courses are, by definition, Category A approved. ASRT members get instant access to 17 free CE credits and then can access their library of 500+ courses spanning radiography, CT, MRI, mammography, nuclear medicine, and radiation therapy.
What it offers CT techs:
- CT-specific courses including head CT protocols, cardiac CT, dual-energy CT, and image quality reviews
- Modality pathways (“Roadmaps”) designed to guide technologists toward CT or MR credentials
- Ethics, patient care, and radiation safety credits that count toward biennial requirements
- Podcast-format CE for auditory learners
Pricing: ASRT membership is required for full catalog access. Individual course pricing available for non-members.
Best for: Technologists who want organizational membership benefits, professional resources, and CE bundled in one subscription.

4. eRadImaging
eRadImaging operates on an annual subscription model that gives unlimited access to over 110 Category A credit courses across all modalities. Every course is approved by the ASRT and accepted by ARRT, ARDMS, NMTCB, ARMRIT (for MRI courses), and CAMRT. Their CT-specific offerings include introductory and advanced modules — “Back to Basics: Introduction to CT” and “Image Production, Evaluation, and Archiving in CT” are among the most-accessed.
What it offers CT techs:
- CT courses ranging from 1.25 to 3.5 credits each
- Unlimited completions for 12 months — complete all 24 credits in one sitting if needed
- No cap on number of credits completed per time period
- Florida electronic CE reporting included; Iowa, Illinois, Kentucky, and Texas state requirements met
- Accepted by NMTCB — relevant for NMTs pursuing CT cross-credentials
Pricing: Annual membership model; competitive flat-rate pricing.
What to keep in mind: eRadImaging tracks completions but does not report to ARRT on your behalf — you must self-report through the ARRT portal.
Best for: Technologists who need to complete CE efficiently and cost-effectively, or who hold multiple credentials (e.g., RT + NMT).

Which Provider Should You Choose?
| Scenario | Recommended Provider |
|---|---|
| Pursuing ARRT CT certification from another modality | MTMI |
| Need 24 credits fast on a tight budget | eRadImaging |
| Want membership, advocacy, and CE in one | ASRT |
| Prefer case-based, image-heavy content | Medality |
| Hold both RT and NMT credentials | eRadImaging or ASRT |
Tips for Maximizing Your CT CE Hours
Align content with your clinical work. ARRT does not require that CE credits be modality-specific for CT technologists — your 24 credits can cover any relevant topic. That said, spending those hours on CT physics, protocol optimization, and dose reduction directly improves your daily practice.
Track Structured Education separately. If you are pursuing CT post-primary certification, you need 16 SE hours from an ARRT-recognized program before sitting for the registry exam. CE hours from providers like MTMI can simultaneously satisfy both your biennial CE requirement and your SE requirement.
Check CQR deadlines. If you earned your credentials on or after January 1, 2011, you have Continuing Qualifications Requirements (CQR) to complete every 10 years. Some CT-specific CE activities qualify for CQR credit — confirm with the provider.
Do not wait until the deadline. The ARRT biennium is tied to your birth month. Waiting until the final weeks creates unnecessary stress. Building a habit of 1–2 CE credits per month keeps you perpetually current.
Conclusion
For CT technologists, the CE market has never been more robust. Whether you want the depth of MTMI’s structured bootcamp, the breadth of ASRT’s 500-course library, the efficiency of eRadImaging’s unlimited subscription, or the diagnostic depth of Medality’s case content, you have options that fit every learning style and budget.
Start by identifying your goal: Are you maintaining credentials, cross-training into CT, or preparing for a specialty registry? Match the provider to that goal, and your next biennium becomes a professional development opportunity rather than a compliance chore.
