Vascular Technology (VT) Specialty Exam Prep

The ARDMS Vascular Technology (VT) specialty exam earns the Registered Vascular Technologist (RVT) credential. It has the lowest first-time pass rate among all seven specialties (70% in 2025) and tests a deep understanding of hemodynamics, Doppler physics, carotid stenosis criteria, DVT protocols, peripheral arterial disease, and abdominal vascular assessment.

What the VT Exam Covers

The Vascular Technology registration is a 170-question, 3 hours computer-based examination administered by the ARDMS. Questions are distributed across the official content domains in published weights, so a candidate who scores well in only one or two areas can still fall short overall. The most reliable way to prepare is to work through every domain in proportion to its weight rather than over-investing in the topics you already enjoy. Across all seven ARDMS specialties, repeat test-takers pass at far lower rates than first-time candidates, which makes thorough, domain-balanced preparation before your first attempt the single highest-value use of your study time.

Who This Exam Is For

The VT credential suits both sonography students sitting for their first registration and practicing sonographers adding a new specialty to an existing credential portfolio. Clinical experience in this area transfers directly to board performance, but the exam also rewards structured review of the published outline because it tests breadth that day-to-day scanning may not. Whether you are studying full time or fitting preparation around shifts, mapping each study block to a specific domain keeps your effort aligned with what the registry actually scores.

How to Prepare

Start by downloading the current ARDMS VT content outline from ardms.org and allocating your study time in proportion to each domain's weight. Use Ultrasound Analytics to practice with 170-question timed exams that mirror the real ARDMS format. After each session, review your domain-level performance breakdown on the analytics dashboard to identify which content areas need more work and adjust your focus accordingly.
