The American Registry of Radiologic Technologists® (ARRT) requires that every student demonstrate competency in a series of mandatory and elective radiological procedures.These procedure checklists make it easy for you to do just that. There's a checklist for each radiographic examination, and each checklist describes every step required for the procedure.Use them while you're learning the procedure and review them as you prepare for the exam. Your instructors and program director can use them to document your progress and verify to the ARRT that you have demonstrated the required competencies and proficiencies.
