ARRT Vascular-Interventional Radiography study guide
ARRT Vascular-Interventional Radiography · Work through your exam, one topic at a time.
ARRT certification and registration in Vascular Interventional Radiography (VI) recognizes technologists qualified to perform the role of a Vascular Interventional Radiographer. These technologists assist physicians with minimally invasive, image-guided vascular procedures - including angioplasty, stenting, and thrombolysis - and use sophisticated fluoroscopic equipment to capture images of blood vessels, working in hospitals, clinics, labs, or outpatient centers. VI is a postprimary credential: candidates must already hold ARRT credentials in an approved supporting discipline (in some cases a supporting credential earned through another organization may qualify), and must also satisfy education, ethics, and examination requirements. ARRT publishes examination content specifications outlining the topics that appear on VI exams, a task inventory of job responsibilities typical of the role, clinical experience requirements describing the type and quantity of procedures to complete, and structured education requirements. The ARRT Vascular-Interventional Radiography study guide has 4 sections and about 1,004 words.
01Image Production and Evaluation
For vascular and interventional work, image production is mostly about fluoroscopic image chains and contrast resolution . Know the order of the chain: x-ray tube → patient → image receptor (image intensifier or flat-panel detector) → signal processing → display.
291 words, about 1 min02Patient Care and Education
Interventional radiography demands informed consent , patient assessment , and contrast safety . Before any procedure, verify identity, allergies (especially iodinated contrast and shellfish/latex), renal function (eGFR/creatinine), pregnancy status, and current anticoagulation.
254 words, about 1 min03Procedures
Know the major vascular and interventional procedures and their indications, access sites, and complications . Common categories: diagnostic angiography (arterial/venous), angioplasty and stenting , embolization (e.g., for bleeding or tumors), thrombolysis/thrombectomy , IVC filter placement , TIPS , central venous access , and biopsy/drainage .

Protection is governed by ALARA and the principles of time, distance, and shielding . Know the inverse square law: doubling distance reduces dose to one-fourth.
