Shares and question counts follow the 2022 content specification, in force through 28 February 2027. The 2027 content specification changes some of them from 1 March 2027.
Patient Interactions
16.5%Covers ethical and legal aspects of care, patient communication, physical assistance and monitoring, medical emergencies, infection control, hazardous materials, and contrast media pharmacology.
Image Acquisition
13%Covers the factors that affect radiographic quality (mAs, kVp, OID, SID, focal spot, grids and more), technique charts, automatic exposure control, digital imaging characteristics, image identification, and image evaluation. ARRT says receptor exposure and spatial resolution where some texts say density and detail. Its factor table adds image contrast and subject contrast columns in the 2027 outline, from 1 March 2027. CR items such as radiation fog are on the 2022 outline only.
Equipment QA
12.5%Covers the x-ray generator and tube, the radiographic and fluoroscopic unit, image receptors and accessories, image processing and display, imaging informatics, and quality control. ARRT lists CR and DR receptors in the 2022 outline, and a digital detector in the 2027 outline, from 1 March 2027. X-ray production sits under Radiation Physics, and the anode heel effect under Image Acquisition.
Radiation Physics
10.5%Covers photon production (bremsstrahlung, characteristic), photon interactions (photoelectric, Compton, coherent), and the cellular and systemic effects of ionizing radiation.
Radiation Protection
14.5%Covers the basic methods (time, distance, shielding), ALARA, minimizing patient exposure, occupational and public dose limits, lead equivalents for protective devices, and dosimetry practices.
Extremity
14%Covers positioning and projections for the fingers, hand, wrist, forearm, elbow, humerus, shoulder, scapula, AC joints, toes, foot, calcaneus, ankle, tibia and fibula, knee, patella, and femur, plus long bone measurement, bone age, bone survey and arthrography. ARRT lists the clavicle here in the 2022 outline and under Thorax in the 2027 outline, from 1 March 2027. It files the hip under Head, Spine and Pelvis in both.
Thorax and Abdomen
10%Covers positioning for the chest, ribs, sternum, soft tissue neck, sternoclavicular joints, abdomen, esophagus, upper GI, small bowel, contrast enema, surgical cholangiography, ERCP, and GU studies. Intravenous urography is on the 2022 outline only, through 28 February 2027. The 2027 outline, from 1 March 2027, moves the clavicle here and adds foreign bodies and tube and line placement.
Head, Spine, and Pelvis
9%Covers positioning for the skull, facial bones, mandible, TMJs, nasal bones, orbits, paranasal sinuses, the cervical, thoracic and lumbar spine, the sacrum and coccyx, SI joints, the pelvis, and the hip. Includes Caldwell, Towne, Waters, SMV, and the lumbar obliques that textbooks call the Scottie dog. ARRT files ribs and sternum under Thorax and Abdomen.

Common questions
How many practice questions are on the ARRT Radiography Boards?
The ARRT Radiography Boards exam contains 200 scored questions plus 30 unscored pilot questions, for a total of 230 questions. It is a computer-based test. ARRT's 2026 handbook gives 230 minutes of test time in a 250-minute appointment. Our mock exams have 200 questions on the same 230-minute clock, so they give more time per question than the real exam. The Radtechprepper practice bank contains 2,584 ARRT-style questions across all 4 ARRT content categories, roughly 13× the scored questions on the actual exam.
What are the 8 ARRT Radiography subcategories?
Patient Interactions and Management, Image Acquisition and Evaluation, Equipment Operation and QA, Radiation Physics and Radiobiology, Radiation Protection, Extremity Procedures, Thorax and Abdomen Procedures, and Head/Spine/Pelvis Procedures. They roll up into ARRT's four content categories, weighted under the 2022 content specification as Patient Care 16.5%, Safety 25%, Image Production 25.5%, Procedures 33%.
Are these practice questions written in the same format as the ARRT exam?
Mostly. Every question here is multiple choice with 4 answer options. One option is correct; the other three are plausible distractors. Each has a rationale explaining the correct answer, and some also cover the wrong options. ARRT's 2026 handbook says most exam questions are multiple choice with one best answer, and some ask you to select multiple answers, sort options into order, select an image, or answer after a short video. We do not have those formats yet. Our mock exams also have no unscored pilot questions.
