What This Exam Actually Is (and Isn't)
Before you build a study plan, be clear about the credential. On this site, RTVI refers to the Registered Technologist credential in Vascular-Interventional Radiography. ARRT's official discipline name is Vascular Interventional Radiography (VI). It is a postprimary credential, meaning you earn it on top of an existing ARRT Radiography credential. "RTVI" is simply the abbreviation used here; it is not ARRT's formal designation. If you want the background on the name, see What Is RTVI? or What Does RTVI Stand For?.
It is also distinct from neighboring credentials. It is not Cardiac Interventional Radiography, not Vascular Sonography, and not the CCI RCIS credential. If you are studying from a resource that emphasizes cardiac cath lab hemodynamics or sonographic vascular physics as the main event, you are studying for a different exam. Every fact in this guide traces to ARRT's VI examination content specifications, which are the controlling document for what can be tested.
For a broader orientation, the RTVI certification overview and the complete domains guide pair well with this article.
Clear Eligibility Before You Open a Book
Many candidates lose weeks because they study before confirming they can sit for the exam. ARRT postprimary eligibility has three moving parts, and the clinical piece is the one that takes longest. The full rundown is in RTVI Requirements: Eligibility, Prerequisites & How to Qualify; here is the working summary.
Foundation: Current Radiography Credential
You must hold current ARRT certification and registration in Radiography and be in compliance with ARRT's ethics requirements. Nuclear Medicine Technology or Radiation Therapy alone is not a supporting credential for VI, so those technologists need a qualifying pathway through Radiography first.
Structured Education: 16 Hours
You need 16 hours of structured education completed within the 24 months before you apply, with at least one credit in each major content category. That last clause is the one people miss: a pile of 16 hours all in procedures does not satisfy the requirement. Check the VI Structured Education Requirements document and confirm your coursework spans Patient Care, Image Production and Procedures.
Clinical Experience: 200 Verified Repetitions
You need current BLS certification from an ARRT-recognized provider and at least 200 verified procedure repetitions within the 24-month eligibility window. The distribution is specific:
- At least 50 in vascular diagnostic procedures
- At least 50 in vascular interventional procedures
- At least 50 in nonvascular procedures
- 50 additional repetitions from any category
Log 5-10 repetitions per selected procedure and no more than 10 logged procedures per day. You must be physically present in an active primary scrub or circulating role throughout the procedure; observation alone does not count. Verification can come from a qualified ARRT-certified and registered technologist, a supervisor or an interpreting physician, and postprimary verifiers do not have to directly observe your work, so remote verification is permitted.
Format, Timing and Scoring Mechanics
The exam is computer-based and delivered at Pearson VUE test centers. It contains 210 questions: 160 scored and 50 unscored pilot questions. You will not know which are which, so treat every question as if it counts.
| Feature | Detail |
|---|---|
| Total questions | 210 (160 scored + 50 unscored pilot) |
| Answering time | 210 minutes |
| Total appointment | 230 minutes, including tutorial, nondisclosure agreement and survey |
| Delivery | Pearson VUE test center |
| Book policy | Closed book |
| Navigation | Answer each item before advancing; flag and revisit permitted |
| Passing score | 75 on the 1-99 scaled score |
| Attempts | Three attempts within three years of the opening of the initial examination window |
| Fees | $225 initial application; $200 examination reapplication |
Question Styles
Most items are single-best-answer multiple choice, but expect image-based questions and possible alternative item formats. ARRT's handbook also describes multiple-response and ordered-response formats. In a vascular interventional exam, image-based items naturally lend themselves to angiographic anatomy, catheter and device recognition, and procedural sequencing. Practice reading angiograms and putting steps in order, not just recalling definitions.
Calculators
The exam is closed book, but basic and scientific on-screen calculators are available, and Pearson can supply a basic four-function calculator on request. Personal calculators are prohibited. Practice the on-screen tool before test day if you expect dose or contrast-volume style calculations.
Understanding the Scaled Score
The most common misconception is that 75 means 75% correct. It does not. ARRT reports a scaled score on a 1-99 range, and 75 is the passing point on that scale. Raw-to-scaled conversion accounts for form difficulty, so do not try to compute a target number of correct answers. Read RTVI Passing Score: Exactly What You Need to Pass for the full explanation, and aim to be comfortably strong across all domains instead of chasing a threshold.
The Content Map: 160 Scored Questions
ARRT publishes scored-question allocations as counts. Retain them as counts rather than converting them into percentages, since the official document does not present percentages.
| Major Content Category | Scored Questions (of 160) |
|---|---|
| Domain 1: Patient Care | 22 |
| Domain 2: Image Production | 26 |
| Domain 3: Procedures | 112 |
Procedures is itself divided into three areas: Vascular Diagnostic Procedures (41), Vascular Interventional Procedures (41) and Nonvascular Procedures (30). Radiation protection sits inside Image Production, not in a separate safety domain, which surprises candidates who expect a stand-alone radiation safety section. For a fuller breakdown, see RTVI Exam Domains: Complete Guide to All 3 Content Areas.
Key Takeaway
Procedures carries 112 of 160 scored questions. A candidate who is excellent at Patient Care and Image Production but shaky on diagnostic and interventional procedures is exposed. Allocate study time in proportion to question counts, then add extra time to your weakest procedure area.
Procedures: Where the Exam Is Won
Because these three areas hold 112 scored items, they deserve the bulk of your preparation. Use the content specifications as your checklist and make sure you can explain each listed procedure end to end.
Vascular Diagnostic Procedures (41 scored questions)
Expect angiographic work across vascular territories, where anatomy, access, imaging approach and contrast considerations all matter.
- Arterial and venous anatomy, including normal variants you must recognize on images
- Access site selection and the typical catheters and wires used for each study
- Imaging projections and sequencing for each territory
- Contrast selection, volume and injection concepts
- Recognizing common pathology on angiograms
Vascular Interventional Procedures (41 scored questions)
This area tests what happens after diagnosis: the devices, indications and complications of therapeutic work.
- Angioplasty, stenting and embolization concepts, including device and agent selection
- Thrombolysis and other flow-restoration approaches
- Vascular access and central venous device placement
- Equipment, guidewire and sheath handling during an intervention
- Recognizing and responding to procedural complications
Nonvascular Procedures (30 scored questions)
Do not neglect this area just because the name suggests it is peripheral to a vascular credential. Thirty scored items is a substantial block, and your 200-repetition requirement includes at least 50 nonvascular cases, so you should have hands-on exposure.
- Image-guided biopsies and drainages
- Percutaneous access to non-vascular structures
- Tray setup, sterile technique and image guidance selection
- Indications, contraindications and post-procedure care
A useful way to study is to pair every procedure with a four-part frame: indication, equipment, technique and complications. Examiners favor questions that test judgment, such as which device suits a scenario or which finding should prompt a change in approach, over rote recitation. Your logged clinical cases are a built-in review resource: revisit each procedure type you logged and test whether you can still explain every step without notes.
Image Production, Including Radiation Protection
With 26 scored questions, Image Production is the second-largest domain, and it is where radiation protection lives. In an interventional suite, where fluoroscopy times are long and staff stand close to the beam, this content has real practical weight.
Domain 2: Image Production
Know the imaging chain and the dose-management decisions an interventional technologist makes constantly.
- Fluoroscopic and angiographic imaging principles, including digital subtraction and road-mapping concepts
- Equipment components and how acquisition parameters change image quality
- Radiation protection for patients, operators and staff, including time, distance and shielding
- Dose-reduction techniques during prolonged fluoroscopy
- Image artifacts and how to recognize and correct them
- Contrast-related imaging considerations
Because radiation protection is folded into this domain, you will not find a separate safety block to study in isolation. Instead, expect it woven into equipment and technique questions. When you review a fluoroscopy topic, always ask yourself what the dose implication is.
Patient Care in the Angiography Suite
Patient Care has the fewest scored items at 22, but these are often the most approachable questions for working technologists. They also cover situations where mistakes carry the highest risk.
Domain 1: Patient Care
Think about the full arc of an interventional patient: before, during and after the procedure.
- Pre-procedure assessment, including relevant labs, allergies, medications and consent
- Monitoring during sedation and recognizing patient deterioration
- Contrast reactions and how to respond
- Sterile technique and infection prevention
- Post-procedure care, including access-site management and patient instructions
- Emergency response in the suite
Do not use the low count as a reason to skip this domain. Twenty-two questions can still be the margin between passing and failing, and these items reward careful, safety-first reasoning that your clinical experience already supports.
A Domain-Weighted Study Sequence
You do not need an elaborate method. You need a sequence that matches the exam's weight. One plan that follows the question counts is below; stretch or compress it to fit your timeline.
Baseline and Image Production
- Read the content specifications cover to cover and mark unfamiliar items
- Review fluoroscopy and angiographic imaging principles and radiation protection
- Take a short diagnostic quiz to find your weakest domain
Vascular Diagnostic Procedures
- Work territory by territory through anatomy, access and projections
- Practice reading angiograms and identifying structures and pathology
Vascular Interventional Procedures
- Study devices, agents, indications and complications for each therapy
- Practice ordering the steps of common interventions
Nonvascular Procedures and Patient Care
- Cover biopsies, drainages and percutaneous access
- Review sedation monitoring, contrast reactions and post-procedure care
Mixed Practice and Weak-Spot Repair
- Take full-length mixed-domain practice sets at exam pace
- Return to the domain where your scores lag and rebuild it
The reason Procedures consumes the middle weeks is simple: it holds 112 of 160 scored items, and it is the area where anatomy knowledge, equipment familiarity and clinical judgment all converge. To gauge how demanding this plan is relative to the exam, see How Hard Is the RTVI Exam? and the RTVI pass rate analysis. ARRT's 2025 Annual Exam Report lists a 61.2% first-time pass rate (n=454). That means roughly four in ten first-time candidates did not pass, which is a good reason not to underprepare.
When you are ready for a final skim, the RTVI cheat sheet condenses the must-know facts into a single review page, though it should supplement your study, not replace it.
Test-Day Mechanics at Pearson VUE
Know the logistics so nothing surprises you. Your appointment lasts 230 minutes, but only 210 of those are for answering. The rest covers the tutorial, the nondisclosure agreement and a survey. Because those 210 minutes cover 210 questions, you have roughly one minute per item on average, which is comfortable for recall questions and tighter for image-heavy or multi-step items.
- Answer to advance. You must answer each item before moving on, but you can flag it and return. Make your best selection, flag uncertain items and use leftover time to revisit them.
- Use the on-screen calculator. Basic and scientific versions are available; request a basic four-function calculator from Pearson if you want a physical option. Personal calculators are not allowed.
- Do not hunt for pilot questions. Fifty unscored items are mixed in. An oddly worded question might be a pilot, but you cannot tell, so give each one full effort.
- Know the retake limits. You have three attempts within three years of the opening of the initial examination window, and reapplication costs $200. Plan to pass the first time. See RTVI Exam Dates: Testing Windows, Deadlines & Scheduling for scheduling details.

After You Pass: Renewal and CQR
Earning the credential is not the end of the paperwork. To keep your certification and registration, you must renew annually. The fee is $65 regardless of how many ARRT credentials you hold. You must also remain in compliance with ARRT ethics requirements and complete 24 approved continuing education credits per two-year biennium. Those 24 credits apply to the biennium as a whole, not to each credential separately, so a technologist holding both Radiography and VI does not double the CE load.
Credentials earned on or after January 1, 2011 also require Continuing Qualifications Requirements every 10 years. That process involves 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, which some technologists prefer.
