What are the best online resources for an ultrasound tech to earn CMEs?

For an ultrasound technologist (sonographer), the best online CME resources are usually the ones that are accepted by your credentialing body (such as ARDMS, ARRT, or CCI), offer sonography-specific content, and make it easy to track certificates. Here are some of the most commonly used options:

Top online CME resources for ultrasound techs

Society of Diagnostic Medical Sonography (SDMS)

sdms.org Best overall choice for diagnostic sonographers

• Large library of ultrasound-focused CME (abdomen, OB/GYN, vascular, breast, cardiac, MSK, protocols, safety, etc.)
• On-demand courses, webinars, and virtual events
• SDMS CME Tracker can help document and transmit eligible credits to ARDMS, ARRT, and CCI for members.Society of Diagnostic Medical Sonography+1

American Society of Radiologic Technologists (ASRT)

asrt.org Best for RT(R)/ARRT professionals who also perform ultrasound

• Online courses, recorded webcasts, and directed reading activities
• Strong documentation and CE tracking
• Many ASRT-approved activities are accepted for ARDMS CME requirements, though you should verify eligibility for your specific credential.ASRT+1

Good for: Technologists maintaining ARRT credentials or those wanting broader imaging education.

---

American Institute of Ultrasound in Medicine (AIUM)

aium.org Best for advanced ultrasound education and clinical updates

• Ultrasound-focused webinars, journal-based CME, and learning activities
• Particularly useful for OB/GYN, point-of-care ultrasound, and clinical practice updates
• AIUM CME activities can be used toward ARDMS certification requirements.www.aium.org

Good for: Sonographers who want deeper clinical knowledge.

---

American Registry for Diagnostic Medical Sonography (ARDMS)

ardms.org Best for checking requirements and approved pathways

• Not primarily a CME course provider, but essential for:

• verifying CME requirements

• checking acceptable activities

• maintaining credentials

---

Ultrasound-specific education companies

These can be useful when you need focused credits quickly:

• urgi.org — registry review and ultrasound education
• pvifoundation.org — useful for vascular-focused learners (check CME eligibility per course)
• gcus.com — long-established ultrasound education provider with online courses and hands-on options

Free or low-cost ways to earn CME

• SDMS member benefits often include access to many on-demand CME activities.Society of Diagnostic Medical Sonography
• Many professional societies offer occasional free webinars.
• Some employers provide access to CME libraries through hospital education platforms.

Tips before you complete a course

1. Confirm the credit type:

• ARDMS: usually needs accepted CME credits plus MOC requirements.
• ARRT: requires approved CE credits within the biennium.
• CCI: has its own CME requirements.Society of Diagnostic Medical Sonography

2. Save:

• completion certificate
• course title
• date completed
• number of credits
• approval number (if provided)

3. Choose courses related to your registry area when possible (for example, vascular CME if you hold RVT).

If you tell me your credential (ARDMS, ARRT, CCI, RVT, RDMS, RDCS, etc.) and specialty (OB/GYN, abdomen, vascular, cardiac, breast, MSK), I can narrow this down to the most useful CME sources for your requirements.

If you’re an ultrasound/sonography tech in the U.S., I’d prioritize resources that are accepted by ARDMS and/or ARRT, depending on your credentials. Also, “CME” and “CE” are often used interchangeably in this context.

Best online CME/CE resources

1. Society of Diagnostic Medical Sonography (SDMS) — Best overall for sonographers

• Probably my first choice if you’re ARDMS-certified.
• Large library of ultrasound-specific online CME covering abdomen, OB/GYN, vascular, breast, MSK, physics, safety, etc.
• SDMS credits are accepted by ARDMS, ARRT, CCI, and Sonography Canada.
• Members get access to unlimited SDMS CME; nonmembers can purchase individual credits for $25 per credit.
• SDMS members also get automatic CME transmission to ARDMS/ARRT/CCI.SDMS+2

sdms.org 2. American Society of Radiologic Technologists (ASRT) — Best if you have ARRT + want ultrasound-specific CE

• Extensive online CE library, including a dedicated Sonography section.
• Particularly useful if you're ARRT-certified in sonography or maintain another ARRT credential.
• ASRT confirms that ARDMS accepts ASRT-approved activities, and ASRT can automatically transfer credits to ARDMS for members who have their ARDMS number in their profile.ASRT+1

asrt.org 3. American Institute of Ultrasound in Medicine (AIUM) — Best for advanced clinical education

• Excellent choice for more specialized ultrasound education, particularly if you want to go beyond simply accumulating credits.
• AIUM is an ARRT-recognized CE approver, which is useful if ARRT requirements apply to you.ARRT

aium.org

My ranking

If you just want the easiest route: I'd start with SDMS. It's highly targeted to sonographers, has a large online catalog, and the automatic ARDMS transfer is a major convenience.SDMS+1

One important caveat: check your specific credential's requirements before buying courses. ARDMS, ARRT, CCI, and individual state licenses can have different rules about what counts and how many credits you need.

If you tell me which credential(s) you have (e.g., ARDMS RDMS, RVT, ARRT(S), RCS) and how many CME hours you need, I can give you a shortlist of the cheapest/best online options to knock them out quickly.

If you’re an ultrasound technologist/sonographer in the U.S., I’d prioritize resources that specifically offer ARDMS-accepted CME/CE and make it easy to document your credits.

• The catalog includes activities with AMA PRA Category 1 Credit and/or ARRT Category A credit, depending on the course.AIUM Learning

My recommendation

If your primary credential is ARDMS, I'd use:

SDMS → AIUM → ASRT

SDMS is the easiest "CME workhorse," while AIUM is especially good when you want high-quality specialty education rather than just checking a CME box.

One important distinction: people often use "CME" and "CE" interchangeably, but your registry may have specific requirements about credit type, specialty content, and reporting periods. Before paying for a course, verify that the activity meets your particular ARDMS/ARRT/CCI requirements.

If you tell me which credential(s) you have (ARDMS, ARRT, CCI, etc.), your specialty (general, OB/GYN, vascular, echo, breast, etc.), and how many credits you need, I can narrow this down to the cheapest/easiest online options and free CME sources for you.

For an ultrasound technologist/sonographer, the best online CME resources are usually the ones that are accepted by your credentialing body (ARDMS, ARRT, CCI, etc.), offer sonography-specific content, and provide easy documentation. Here are some of the strongest options:

Medical Professionals

Free or low-cost CME sources worth checking

• SDMS free/low-cost offerings (some require membership; some can be purchased individually)SDMS
• AIUM member webinars and journal CME optionswww.aium.org
• Employer-provided CME libraries (many hospitals subscribe to education platforms)
• Vendor education from ultrasound manufacturers (verify that the activity is actually accepted for your credential)

My suggested strategy

• General sonographer (RDMS/RVT/RDCS): Start with SDMS.
• OB/GYN: Add AIUM.
• Echo: Use ASE + SDMS.
• Vascular: Use SVU + SDMS.
• Need many credits quickly before renewal: Look for on-demand bundles from SDMS, Gulfcoast, or other ARDMS-accepted providers.

Before paying for a course, confirm that the specific activity is accepted for your credential (ARDMS, ARRT, or CCI), because not every ultrasound-related educational activity counts as CME.inteleos.org

If you tell me your credential (RDMS, RVT, RDCS, ARRT(S), etc.) and specialty (OB, abdomen, vascular, echo, breast, MSK), I can narrow this down to the best CME sources for your exact renewal needs.
