- RTVI training means 16 structured-education hours plus at least 200 verified procedure repetitions, both inside a 24-month window.
- The 200 repetitions require at least 50 each in vascular diagnostic, vascular interventional and nonvascular, plus 50 from any category.
- Observation does not count; you must be physically present in an active scrub or circulating role.
- Procedures carries 112 of 160 scored questions, so most of your study time belongs there.
What "RTVI Training" Actually Covers
Searches for "RTVI training" usually mix together three different things: the education you must document before applying, the hands-on procedure experience you must log, and the studying you do for the exam itself. On this site, RTVI refers to the postprimary credential in Vascular Interventional Radiography (VI) offered by the American Registry of Radiologic Technologists (ARRT). RTVI is this site's shorthand; ARRT's official discipline name is Vascular Interventional Radiography. If you are new to the terminology, our explainers on what RTVI is and what RTVI stands for cover the naming in more detail.
The key point is that this credential does not have a single training program you enroll in and graduate from. ARRT sets requirements, and you assemble your own training path from approved structured education, supervised clinical work and exam preparation. That makes planning more important than it is for a primary pathway, because the requirements run on overlapping clocks.
The Prerequisite Layer: Radiography First
Because VI is a postprimary credential, the first form of training is the one you have already completed. You need current ARRT certification and registration in Radiography, and you must be in compliance with ARRT's ethics requirements. This is a firm gate: ARRT's supporting-credential rules specify that Nuclear Medicine Technology or Radiation Therapy alone is not a supporting credential for VI.
If you hold only one of those credentials, you would need to add Radiography before this pathway opens to you. Our RTVI requirements guide walks through eligibility in full, so confirm your status there before spending money on courses.
Structured Education: 16 Hours With a Catch
The structured-education requirement is 16 hours completed within the 24 months before you apply. The catch is distribution: you need at least one credit in each major content category, which means Patient Care, Image Production and Procedures all have to be represented. You cannot satisfy the requirement by stacking 16 hours of procedural lectures.
Practical advice for choosing coursework:
- Check the Vascular Interventional Radiography Structured Education Requirements document (effective July 1, 2023) and match each course to a category before you pay for it.
- Keep certificates showing the date, hours and provider, since the 24-month lookback is measured from your application.
- Do not assume all your continuing education counts. Activities must be approved for the structured-education purpose, and the category mapping matters.
Clinical Training: The 200-Repetition Log
This is the heart of RTVI training. The clinical experience requirements (effective July 1, 2023) demand at least 200 verified procedure repetitions within the 24-month eligibility window, plus current BLS certification from an ARRT-recognized provider.
| Category | Minimum Repetitions |
|---|---|
| Vascular diagnostic | 50 |
| Vascular interventional | 50 |
| Nonvascular | 50 |
| Additional, from any category | 50 |
| Total | 200 |
Rules that shape how you log
- Presence and role: You must be physically present in an active primary scrub or circulating role throughout the procedure. Watching from the control room, or observing without a defined role, does not qualify.
- Repetition limits: Record 5 to 10 repetitions per selected procedure, and log no more than 10 procedures per day. This prevents a log dominated by one procedure type or a few marathon days.
- Verification: A qualified ARRT-certified and registered technologist, supervisor or interpreting physician must verify your experience. Postprimary verifiers do not have to directly observe your work and may verify remotely, which helps if your supervising radiologist is off-site.
Key Takeaway
The category minimums are where candidates stall. Many departments are heavy on vascular interventional work and light on nonvascular cases, or the reverse. Audit your log monthly against all three 50-repetition minimums, and ask your lead technologist early about rotations that fill your thinnest category.
Because the log is capped at 10 per day and 5 to 10 per procedure, you cannot rush it. Two hundred repetitions typically means sustained exposure across many different procedures, which is exactly the breadth the exam later tests.
Training for the Exam Content
ARRT's Vascular Interventional Radiography Examination Content Specifications (board approved July 2022, effective July 1, 2023) divide the exam into three major content categories. Of the 160 scored questions, the official allocations are:
| Domain | Scored Questions (of 160) |
|---|---|
| Patient Care | 22 |
| Image Production | 26 |
| Procedures | 112 |
Within Procedures, the split is Vascular Diagnostic Procedures (41), Vascular Interventional Procedures (41) and Nonvascular Procedures (30). Our complete guide to the three RTVI content areas breaks down each category in more depth. Here is how the training emphasis should map.
Domain 3: Procedures (112 questions)
This is the exam. Roughly seven of every ten scored items sit here, so your clinical repetitions double as your most valuable study.
- Vascular diagnostic: know the indications, access routes, contrast considerations and imaging approach for diagnostic studies.
- Vascular interventional: be fluent in the equipment, devices and technologist's role in treatment procedures.
- Nonvascular: do not neglect this 30-question block, since it overlaps the category many candidates log least.
Domain 2: Image Production (26 questions)
Radiation protection sits inside this domain rather than in a separate safety section, so dose awareness and imaging technique are studied together.
- Fluoroscopic and angiographic imaging principles and equipment operation.
- Dose management practices for patient and personnel.
- Image quality factors and how technique choices affect them.
Domain 1: Patient Care (22 questions)
The smallest domain, but it contains questions that are reliably answerable if you have done the work.
- Patient assessment, preparation and monitoring around sedation and procedures.
- Sterile technique and infection control in the procedure room.
- Response to adverse events and communication with the care team.
A useful rule of thumb: let your study hours track the question counts, but pad Patient Care slightly, because candidates tend to underprepare it. For a structured plan built around these numbers, see our RTVI study guide.
Training for the Exam Format
Knowing the content is not enough if the testing experience surprises you. The exam is delivered at Pearson VUE test centers and is computer-based and closed book. It contains 210 total questions: 160 scored and 50 unscored pilot questions. You get 210 minutes of answering time, within a 230-minute appointment that also covers the tutorial, nondisclosure agreement and survey.
- Item types: Mostly single-best-answer multiple choice, with possible image-based questions and alternative formats. ARRT's handbook also describes multiple-response and ordered-response items, so practice more than one style.
- Navigation: You must answer each item before moving forward, but you can flag questions and return to them.
- Calculators: Basic and scientific on-screen calculators are provided, and Pearson can supply a basic four-function calculator on request. Personal calculators are prohibited.
Scoring is another place training pays off. The passing score is 75 on ARRT's 1-99 scaled-score range, not 75% correct. Scaled scores account for differences in difficulty between exam forms, so a raw percentage is not a reliable target. Our passing score explainer covers how to interpret your result.
Sequencing Your Training Across the 24-Month Window
Because the education and clinical clocks both run for 24 months, sequencing is the most underrated part of RTVI training. One sensible arrangement ties exam study to the domains in a deliberate order:
Foundation and Logging Setup
- Confirm Radiography registration and BLS status.
- Start the procedure log immediately and note your category counts.
- Take structured-education courses across all three categories.
Clinical Accumulation
- Rotate toward the category where you have the fewest repetitions.
- Read up on each procedure the week you perform it, which anchors Domain 3 content.
Exam-Focused Review
- Weeks 1-4: Procedures, split evenly among diagnostic, interventional and nonvascular.
- Weeks 5-6: Image Production, with radiation protection folded in.
- Weeks 7-8: Patient Care, then full-length timed practice under 210-minute conditions.
Before you commit to a date, check the details in the RTVI exam dates guide. Remember also that candidates get three examination attempts within three years of the opening of the initial examination window, so a rushed first attempt costs more than a slightly delayed one. A retake requires a $200 reapplication fee on top of the $225 initial application, which our certification cost breakdown puts in context.
Training After You Pass: Renewal and CQR
Training does not end at the score report. To keep the credential you must renew annually ($65, regardless of how many ARRT credentials you hold), stay compliant with ethics requirements and complete 24 approved CE credits per two-year biennium. That 24 is per biennium, not per credential, so a technologist holding Radiography plus VI does not double the load.
Credentials earned on or after January 1, 2011 also fall under Continuing Qualifications Requirements (CQR) every 10 years, which involve a professional profile, a structured self-assessment and any prescribed CE. ARRT also lets you accept the maximum CQR CE prescription instead of taking the self-assessment. Choosing CE topics that stay close to vascular and interventional work keeps your skills current and helps with the practice-based self-assessment.
