What it pays

How much does this credential pay?

Radiologic technologists earned a May 2024 BLS median of $77,660, and the CI credential is the specialized pathway into cardiac catheterization labs.

The salary conclusion for the Cardiac Interventional credential is a specialization premium story: the BLS Occupational Outlook Handbook reports a May 2024 median annual wage of $77,660 for radiologic technologists and technicians within SOC 29-2034 Radiologic and MRI Technologists, and the CI designation is the standard qualification for technologists who staff cardiac catheterization and electrophysiology labs, which sit above the general radiography median because the work is invasive, high-acuity and performed in hospital settings with on-call responsibility. The BLS classifies by job duty, not by certificate, so the R.T.(R)(CI) designation itself does not appear in the wage data — but cardiac cath labs, which almost exclusively employ CI-certified technologists, pay a premium over the median for candidates who can scrub into coronary and electrophysiology cases, and the credential converts a general radiographer into a cardiac-specialty technologist in a way that shows up in base pay, shift differentials and call pay. The broader occupation is a large one — 272,000 radiologic and MRI technologists in 2024 — with BLS projecting about 5 percent growth from 2024 to 2034 and roughly 15,400 openings a year, so the entry pool is deep and the CI credential is one of the ways a technologist differentiates into a higher-acuity, higher-paying setting. Two caveats anchor the picture: first, the CI exam is post-primary, so it requires an existing ARRT primary credential first, and the salary story has two steps — the primary radiography credential and then the cardiac specialization; second, the earnings premium depends on the employer and market, with metropolitan cardiac programs paying the most while smaller facilities may pay flat across modalities. For a candidate asking whether CI pays, the direct answer is yes, reliably above the radiography median, and the credential is one of the highest-premium post-primary specializations an employed radiographer can add, even though the exam itself is the hardest of the ARRT post-primary tests.

Your schedule

How long should I study for it?

140-180 hours over 12-14 weeks of focused study

An efficient ARRT Cardiac Interventional study plan is 12-14 weeks of about 140-180 total hours, because the exam is not only broad but the hardest post-primary credential ARRT offers — the 2025 first-attempt pass rate was 52.9 percent and the all-candidate mean scaled score sat at 74.9, below the passing 75 — so the plan must assume the bar is higher and the margin thinner than on any sibling exam. The 145 scored items span four categories, and the two procedure categories carry most of the paper: Interventional Procedures (50 items), Patient Interactions and Management (40), Diagnostic and Electrophysiology Procedures (35), and Image Acquisition and Equipment (20). The published content specifications are the scope map, and studying the categories in proportion to their item counts is the single highest-yield planning decision, with the interventional procedure content receiving the largest block because it is 34 percent of the paper and the most clinically demanding. Candidates already working in a cardiac cath or EP lab arrive with a large advantage in the procedure content; candidates moving from general radiography without cardiac exposure should budget the upper end and add structured education early, because coronary anatomy, hemodynamics, device selection and electrophysiology are genuinely new rather than review. The post-primary eligibility gates must be finished before the study window: an existing ARRT primary credential, the structured education requirement for cardiac interventional radiography, and the documented clinical experience required by the post-primary pathway. The final four weeks should be question-bank and mock-exam work at the real format, with at least three full timed mocks, because the appointment runs several hours with mixed pilot questions and the exam report shows that the majority of candidates fail — pacing and procedure depth are what separate the passing minority.

1. Week 1-230

   Patient care and image acquisition

   • Study patient interactions in the cath lab: consent, monitoring, sedation, hemodynamic stability and contrast administration
   • Cover image acquisition and equipment: fluoroscopy, cine, digital subtraction, image chains and quality control
   • Drill radiation protection and dose management for cardiac procedures
2. Week 3-540

   Diagnostic and electrophysiology procedures (35 items)

   • Study coronary angiography, ventriculography, and the diagnostic studies of the cardiac catheterization lab
   • Cover electrophysiology studies, pacing, ablation concepts and device procedures
   • Drill cardiac anatomy, physiology and hemodynamic monitoring
3. Week 6-950

   Interventional procedures (50 items)

   • Study coronary angioplasty and stenting, thrombectomy, and the interventional techniques of the cath lab
   • Cover device selection, deployment, complication management and post-procedure care
   • Work case-based review of when each intervention is indicated and how it is performed, including emergencies
4. Week 1015

   Gap closing and first mock

   • Re-test the Week 1-2 patient care and image acquisition items
   • Re-drill the procedure distinctions that the miss log shows are recurring
   • Take one full timed mock exam
5. Week 11-1435

   Mocks and readiness

   • Take three more full-length timed mocks scoring above scaled 75
   • Re-drill the miss log until clean, weighted to the interventional procedure category
   • Confirm Pearson VUE booking, photo ID requirements and the testing window deadline

What to buy

Which study resources are worth paying for?

ARRT Cardiac Interventional prep resources split into the free official set, current question banks, and structured courses, and the buying logic is dominated by two facts: ARRT revises its content specifications on a published cycle, so material published for earlier revisions risks testing candidates against an outdated outline, and the CI exam is the hardest post-primary credential ARRT offers, with a 52.9 percent first-attempt pass rate in 2025, so under-investing in preparation is a bad bet. The free ARRT stack — the content specifications document, the post-primary eligibility pathway handbook, and the candidate resources on the ARRT website — covers the scope definition completely at zero cost and should anchor every plan. The paid question bank is the standard purchase, with prices typically $60-150 for a subscription that includes explanations, image items and mock exams; for an exam this hard, the bank is closer to a necessity than an option, and a bank with image-based and case-based items is worth the premium. Structured courses and live review workshops run $200-600 and add video instruction and pacing, which helps candidates who want external structure or who are weak in the cardiac anatomy and electrophysiology content, and a cardiac-interventional review text with case studies runs $100-200 as a supplement. The footnote that anchors the comparison: prices below are list prices as of mid-2026 and change frequently, and we rank nothing by commission. Employers are the hidden variable: many cardiac catheterization programs pay for or reimburse CI prep materials because the credential directly expands what the lab can offer, so candidates should ask their manager before buying anything, and a cheap readiness check is taking the free sample items ARRT and its vendors publish before purchasing — and treating a low score as the signal that the full study plan, not a shorter one, is warranted.

What you'll face

What question types will I see?

The ARRT Cardiac Interventional exam is 145 scored items plus unscored pilot questions delivered by computer at Pearson VUE centers, in a multi-hour appointment, and the published format is four-option, single-best-answer multiple choice with a small share of alternative formats such as image-based items and multiple-select items. The scored content follows the four categories reported in the ARRT Annual Exam Report: Interventional Procedures (50 items), Patient Interactions and Management (40), Diagnostic and Electrophysiology Procedures (35), and Image Acquisition and Equipment (20). The interventional and patient-interaction categories together carry 62 percent of the paper, and the items reward knowing the full arc of a cardiac case — access, diagnostic findings, device selection, deployment, complication management and post-procedure care — plus the hemodynamics and monitoring that keep the patient stable through it. The exam includes image-based items in which candidates identify coronary anatomy, recognise device placement, or interpret a pressure waveform or angiogram, which is why studying with images matters and why case-based review is a standard prep method. The electrophysiology layer, including EP studies, pacing and ablation concepts, is the content most likely to separate candidates who came from general radiography, because it sits outside the imaging-tech curriculum and the report shows it as a distinct scored block. Because the pilot items are indistinguishable from scored ones, every question must be treated as live, and because this exam fails most first-time candidates, practice should move from recall items to full case scenarios and multiple timed mocks as the exam approaches. The samples below illustrate the published item style across three of the categories — a patient-care item, a diagnostic-procedure item and an interventional-procedure item — with four options each. The sample items are editor-written illustrations of the published blueprint, not live exam items.
