The American Registry of Radiologic Technologists (ARRT) now has a CT certification and registration program where accreditation is earned from the National Commission for Certifying Agencies (NCCA).
The accreditation serves as an objective measure of a certification program's quality, according to ARRT. The accreditation standards address all areas of a certification program, from the psychometric characteristics of the exam to the organization's governance structure.
ARRT currently has more than 61,000 certified and registered CT technologists. Candidates who meet ARRT's CT clinical requirements must demonstrate the ability to perform diagnostic CT scans for a wide range of radiographic studies, both with and without intravenous contrast.
