Limited Scope of Practice in Radiology Exam

Working with radiography equipment requires special skills. That’s why the American Registry of Radiologic Technologists (ARRT) has developed the Limited Scope of Practice in Radiology exam. These professionals must demonstrate they know how to properly use radiographic equipment. The AART administers the exam for candidates who have been approved by their state licensing organization. Here’s a guide to taking the exam, as well as a look at an outstanding set of study materials you can use for your preparation.
