Radiography PREP (Program Review and Examination Prep), fifth edition, is for use throughout all phases of radiography education. This text is useful for regular coursework, helping the student extract fundamental key concepts from reading assignments and class notes, and for making study and test preparation easier and more productive. PREP is also useful for students preparing for their American Registry of Radiologic Technologists (ARRT) certification examination. It helps students direct their study efforts toward examination-related material and includes registry-type multiple-choice questions designed to help students practice test-taking skills they will need for the ARRT radiography examination. The ARRT’s Content Specifications for the Examination in Radiography lists the examination’s five content categories and provides a detailed list of the topics addressed in each category. Radiography PREP is divided into five parts reflecting each of the five content categories. Part content reflects changes to the ARRT Content Specifications implemented January 2008. Particularly important is updated and expanded information on Digital/Electronic Imaging. Thus, study becomes even more directed and focused on examination-related material. Used with its companion book, Lange Q&A for the Radiography Examination , PREP provides a thorough preparation for the certification examination administered by the ARRT.
