Quick answer
> Quick answer: RVT stands for Registered Vascular Technologist. It’s the vascular sonography credential issued by ARDMS, earned by passing the SPI exam plus the Vascular Technology (VT) exam. It tells employers a sonographer is registered to image blood vessels — arteries and veins. A closely related but separate credential, the RVS, covers the same field but comes from a different body, CCI.
If you’re looking into vascular sonography, RVT is the credential that comes up first. Here’s what it is, how it’s earned, what makes it different from the similarly named RVS, and where it fits in the larger world of sonography credentials.
What RVT stands for
RVT is the Registered Vascular Technologist credential. It’s issued by ARDMS — the American Registry for Diagnostic Medical Sonography, one of three nationally recognized sonography credentialing bodies.
The “vascular” part is the key. This credential is specifically for sonographers who image the vascular system — the body’s arteries and veins. When a sonographer has “RVT” after their name, it means they’re registered in vascular ultrasound through ARDMS.
What vascular sonographers do
Vascular sonography is one specialty within a multi-specialty profession. Sonography as a whole spans abdominal, breast, cardiac, musculoskeletal, OB/GYN, pediatric, and vascular work. Vascular is the branch focused on blood vessels.
Vascular sonographers use ultrasound to look at how blood is moving through the body — checking for blockages, narrowing, clots, and other issues in arteries and veins. It’s a distinct skill set from, say, cardiac sonography (the heart itself) or abdominal sonography (organs). People who specialize in vascular imaging describe it as detail-heavy work, often involving careful measurement of blood flow.
The RVT is the credential that formally marks someone as registered in this area.
How the RVT is earned: SPI plus the VT exam
The RVT follows the standard ARDMS two-exam structure. You pass two exams to earn it.
- The SPI exam — Sonography Principles & Instrumentation. This is the physics-and-equipment exam shared across ARDMS credentials. It covers how ultrasound works: sound waves, image formation, and the machine itself.
- The Vascular Technology (VT) exam — the specialty exam. This is where you demonstrate knowledge of vascular anatomy, blood flow, and the imaging protocols specific to arteries and veins.
Pass both, and you’re an RVT. Like all ARDMS credentials, the RVT is earned by examination only — there’s no alternative route. And you have to meet ARDMS eligibility prerequisites before you can sit for the exams.
RVT vs. RVS — same field, different body
This is the part that confuses people, and it’s a fair confusion. There are two vascular credentials with very similar names.
- RVT — Registered Vascular Technologist, issued by ARDMS.
- RVS — Registered Vascular Specialist, issued by CCI (Cardiovascular Credentialing International).
Both are vascular sonography credentials. Both signal that a sonographer is registered to do vascular imaging. But they come from different organizations, and they’re distinct credentials — not two names for the same thing.
A vascular sonographer might hold the RVT, the RVS, or in some cases both. Which one someone has often traces back to the program they trained in or the lab they work in. When you see RVT and RVS side by side on job postings, that’s why — employers in vascular labs frequently accept either, because both are recognized credentials in the same specialty.
Where RVT sits among ARDMS credentials
ARDMS issues four primary sonography credentials, and RVT is one of them:
- RDMS — general (Registered Diagnostic Medical Sonographer)
- RDCS — cardiac (Registered Diagnostic Cardiac Sonographer)
- RVT — vascular (Registered Vascular Technologist)
- RMSKS — musculoskeletal
So RVT is the vascular member of the family. A sonographer who specializes in blood-vessel imaging through ARDMS earns the RVT specifically. Some sonographers hold more than one of these — for example, RVT alongside another credential — because each new specialty adds one specialty exam on top of the SPI exam they already passed.
Keeping the credential active
The RVT, like other ARDMS credentials, isn’t permanent on its own. It’s maintained through ARDMS’s Maintenance of Certification program.
That means continuing education on a recurring three-year cycle — 25 CMEs for holders of RDMS, RDCS, RVT, or RMSKS — plus an annual attestation, a renewal fee, and an annual knowledge check. So earning the RVT is the start of registration, and keeping it current is ongoing upkeep across a career.
Key takeaways
- RVT is the Registered Vascular Technologist credential — the ARDMS vascular sonography registration.
- It’s earned the standard ARDMS way: pass the SPI exam plus the Vascular Technology (VT) specialty exam.
- RVT (ARDMS) and RVS (CCI) are distinct vascular credentials from different bodies — closely related but not the same.
- RVT is one of ARDMS’s four primary credentials, alongside RDMS, RDCS, and RMSKS.
- Like other ARDMS credentials, the RVT is kept active through continuing education on a three-year cycle plus annual steps.
