Radiologist Assistant

Radiologist assistants are experienced, registered radiographers who have obtained additional education and certification that qualifies them to serve as radiology extenders. They work under the supervision of a radiologist to provide patient care in the diagnostic imaging environment. Specifically, an RA takes a leading role in patient management and assessment. In addition, an RA performs selected radiology examinations and procedures under the supervision of a radiologist. The RA also may be responsible for evaluating image quality, making initial image observations and forwarding those observations to the supervising radiologist.

Although RAs can perform functions beyond those of a radiologic technologist, the position holds certain limitations. An RA may make initial observations of images, but may not draft an official written interpretation.

Radiologist assistants complete an academic program and a radiologist-supervised clinical internship. An RA must be certified by the American Registry of Radiologic Technologists. Currently, there are nine Registered Radiologist Assistant programs in the country recognized by ARRT and seven of the programs offer master's degrees.
