About this exam
The American Registry of Radiologic Technologists (ARRT) Computed Tomography Certification Examination assesses whether eligible radiologic professionals have the knowledge and judgment needed for CT practice. It is generally pursued as a postprimary credential by technologists who already hold an eligible ARRT supporting credential and meet current education and clinical experience requirements. The exam is relevant to technologists seeking to demonstrate competency in computed tomography, including patient care, scan preparation, image acquisition, and safe use of CT equipment.
ARRT CT exam topics include patient assessment, preparation and care; contrast media, injection procedures and adverse reactions; radiation physics and scanner technology; radiation protection and patient dose management; and CT procedures. Preparation involves more than memorizing terminology: candidates need to apply protocols and safety principles to clinical scenarios and understand how technical choices affect image quality and dose. Review the current ARRT CT examination content specifications and candidate handbook, since requirements and exam details can change. A small amount of timed question practice can help identify areas that need further review.
How to prepare for the ARRT CT certification exam
- Use the current ARRT CT content specifications as a checklist. Review patient assessment and preparation, contrast administration and reaction management, scanner physics, dose and radiation protection, and CT procedures.
- Study clinical scenarios alongside the underlying concepts. For example, connect patient history and contrast considerations with preparation decisions, and relate acquisition settings to image quality and dose.
- Use timed, exam-style questions to find weak areas, then review the reasoning behind each answer rather than relying on recall alone. Confirm eligibility, documentation, and current exam guidance in ARRT’s official materials.
