Master the digital radiography concepts tested on the ARRT Radiography exam. Learn the differences between CR and DR, image receptors, Exposure Index (EI), dose creep, PACS, DICOM, digital image processing, and the clinical decision-making skills every radiologic technologist needs. Quick
Confused between radiography and radiology? It’s easy to mix the two up. While the two are closely connected, they play very different roles in healthcare. One focuses on capturing the images doctors need, while the other focuses on studying those images to understand what’s happening inside the body. If you’ve ever wondered what sets them apart, this guide will walk you through it in a clear and simple way.
Learn how to evaluate radiographic images like a radiologic technologist. This complete ARRT study guide explains image quality, positioning errors, exposure errors, artifacts, collimation, and the clinical decision-making skills tested on the ARRT Radiography exam. Quick Answer Taking an x-ray

Many radiography students assume that passing the ARRT exam automatically gives them permission to work. It doesn’t. In most cases: 👉 ARRT certification and a state license are two separate things. While they are closely connected, they serve different purposes.
The ARRT does not publish a fixed number of questions you can miss and still pass. This is because the ARRT uses a scaled scoring system rather than a simple percentage-based grading method. As a result: 👉 Two candidates can
Becoming an ARRT-registered technologist is a major step for anyone pursuing a career in radiologic technology. It shows that you meet the education, ethics, and exam standards required. In this guide, we’ll walk through what ARRT certification is, why it matters, and how you can earn it.
