Sample VI Practice Questions

Try these sample questions to test your VI exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Before a percutaneous interventional vascular procedure, what is the recommended target activated clotting time (ACT) range after heparin administration?

A.100-150 seconds

B.150-200 seconds

C.250-300 seconds

D.400-500 seconds

Explanation: For percutaneous interventional vascular procedures, the target ACT is typically 250-300 seconds to balance thrombotic and bleeding risk during catheter manipulation and intervention.

2Which agent reverses the anticoagulant effect of unfractionated heparin?

A.Vitamin K

B.Protamine sulfate

C.Flumazenil

D.Naloxone

Explanation: Protamine sulfate binds heparin to neutralize its anticoagulant effect; the typical dose is 1 mg per 100 units of active heparin.

3A patient with severe renal insufficiency (eGFR < 30) requires lower extremity angiography. Which contrast strategy minimizes nephrotoxic risk?

A.High-osmolar iodinated contrast

B.CO2 angiography

C.Gadolinium at standard MR doses

D.Double-dose iodinated contrast with mannitol

Explanation: CO2 is non-nephrotoxic and non-allergenic, making it the preferred contrast for infrarenal angiography in patients with eGFR < 30 or contrast allergy.

4Which of the following is NOT a typical branch of the abdominal aorta?

A.Celiac trunk

B.Superior mesenteric artery

C.Internal thoracic artery

D.Renal arteries

Explanation: The internal thoracic (mammary) artery arises from the subclavian artery, not the abdominal aorta. The celiac, SMA, renal, IMA, and lumbar arteries are abdominal aortic branches.

5In a Stanford Type A aortic dissection, the intimal tear involves which segment?

A.Ascending aorta

B.Aortic arch only

C.Descending thoracic aorta only

D.Abdominal aorta only

Explanation: Stanford Type A dissection involves the ascending aorta (regardless of distal extension) and is a surgical emergency. Type B does NOT involve the ascending aorta.

6Which embolic agent is most appropriate for permanent occlusion of a single, discrete arterial branch (e.g., splenic artery for trauma)?

A.Gelfoam slurry

B.Pushable or detachable coils

C.100-300 micron PVA particles

D.Absolute ethanol

Explanation: Coils provide targeted, permanent mechanical occlusion of discrete vessels and are standard for proximal vascular embolization such as splenic trauma.

7What is the minimum number of structured education hours ARRT requires for the Vascular-Interventional Radiography postprimary pathway?

A.8 hours

B.12 hours

C.16 hours

D.24 hours

Explanation: ARRT requires 16 hours of structured education in vascular-interventional radiography for the postprimary pathway.

8How many vascular-interventional procedures must be logged within two years to qualify for the ARRT VI exam?

A.100

B.150

C.200

D.250

Explanation: ARRT requires documentation of 200 vascular-interventional procedures completed within a 24-month window for the VI postprimary credential.

9Which Universal Protocol step must be performed immediately before the skin incision or arterial puncture?

A.Pre-procedure huddle

B.Time-out

C.Sign-out

D.Debrief

Explanation: The time-out is conducted immediately before the procedure starts to verify correct patient, site, and procedure with the entire team present.

10What is the standard vascular access site for most diagnostic abdominal angiograms?

A.Common femoral artery

B.Brachial artery

C.Axillary artery

D.Popliteal artery

Explanation: The common femoral artery (CFA) over the femoral head is the standard access for most diagnostic angiograms because it allows compression against the bone for hemostasis.

About the VI Exam

ARRT post-primary credential for vascular-interventional (non-cardiac) radiologic technologists. NOTE: VI and CI (Cardiac-Interventional) are TWO DISTINCT current credentials; the legacy combined CV (Cardiovascular-Interventional) credential is no longer issued for new candidates but existing holders may maintain it. VI validates expertise in vascular anatomy/pathology, sterile technique, pharmacology (contrast, heparin/ACT, sedation, vasoactive), imaging equipment (DSA, IVUS, FFR), diagnostic angiography, and interventional procedures (PTA, stent, embolization, EVAR, TIPS, IVC filter, AV access).

VI Study Tips from Top Performers

1Master ACR 2022 contrast: low-osmolar preferred; eGFR ≥30 generally safe; metformin NOT routinely held for IV contrast in normal renal function

2Memorize ACT goals: 250-300 for percutaneous interventions; 300+ for cardiac PCI

3Know Greenberger steroid prep for prior contrast allergy: prednisone 50 mg at 13h/7h/1h pre + diphenhydramine 50 mg 1h pre

4Understand sedation reversal: midazolam → flumazenil 0.2 mg IV; opioid (fentanyl) → naloxone 0.4-2 mg IV

5Apply skin dose threshold: 2 Gy = potential deterministic effects; document fluoro time + dose for QA

Frequently Asked Questions

What's the difference between VI and CI?

ARRT VI (Vascular-Interventional Radiography) covers non-cardiac vascular interventions (angiography, PTA, stent, embolization, EVAR, TIPS, IVC filter, AV access). ARRT CI (Cardiac-Interventional) covers cardiac procedures (cardiac cath, PCI, structural cardiac, EP). They are TWO DISTINCT current credentials. The legacy combined CV (Cardiovascular-Interventional) credential is no longer issued for new candidates as of around 2010 — existing holders may maintain it for life.

What contrast considerations should I know?

ACR 2022 Contrast Manual: low-osmolar non-ionic iodinated contrast preferred. Eligibility: eGFR ≥30 generally safe (CIN risk overemphasized historically); eGFR <30 use sparingly, hydration, alternative imaging. Metformin: ACR 2022 — NOT routinely required to hold for IV contrast in patients with normal renal function; hold 48h post-contrast in patients with AKI/eGFR <30. CO2 angiography for renal failure or contrast allergy. Allergy prep (Greenberger): prednisone 50 mg PO at 13h, 7h, 1h pre-contrast + diphenhydramine 50 mg 1h pre.

What are typical interventional procedures?

Common VI procedures: balloon angioplasty (PTA) ± stent (bare-metal, drug-eluting, covered); atherectomy; embolization (coils, particles, glue, Onyx, Amplatzer plug); EVAR/TEVAR for AAA/TAA; IVC filter (retrievable preferred); TIPS for portal hypertension; uterine artery embolization (UAE) for fibroids; transarterial chemoembolization (TACE) for HCC; hemodialysis fistulogram and intervention; catheter-directed thrombolysis (tPA); mechanical thrombectomy; carotid stenting with embolic protection; PE intervention (catheter-directed lysis, mechanical thrombectomy).

How should I study for ARRT VI?

Plan 80-120 hours over 12-16 weeks. Focus on Interventional Procedures (20%), Vascular Anatomy/Pathology (20%), and Pharmacology + Imaging Equipment (30% combined). Master ACT goals (250-300 for percutaneous; 300+ for cardiac), ACR 2022 contrast/metformin guidance, vascular family selectivity, and the procedural workflow (sheath access, catheter selection, intervention).
