What is a Radiologist Assistant? 

The radiologist assistant is an allied health care professional providing a recognized advanced clinical role for experienced radiologic technologists.

A radiologist assistant (RA) enhances patient care by extending the capacity of the radiologist in the diagnostic imaging environment. The RA performs patient assessment, patient management, fluoroscopy, and other radiology procedures. This new health care professional will also make initial observations of diagnostic images, with official interpretations and final written reports being provided by supervising radiologists (as defined by the American College of Radiology (ACR) Standard for Communication: Diagnostic Radiology). 

Radiologist Assistants are supported by the American Society of Radiologic Technologists (ASRT) www.asrt.org and the American Registry of Radiologic Technologists (ARRT) www.arrt.org  For more information do a site search for "radiologist assistant" on any of these sites.  There is also more general information about RA role delineations, practice standards, curriculum, clinical competencies, and RA programs nationwide on the ASRT and ARRT websites. 


For thirty years, the MSU Radiologic Sciences Department has been involved in advanced radiologic sciences education including coordination of numerous off-campus clinical experiences. In a southern state with a population of over 21 million, the current department has the only entry-level Bachelor of Science in Radiologic Technology (BSRT) Degree program in Texas and the only totally online Bachelor of Science in Radiologic Sciences (BSRS) program in the state. ARRT registered technologists may earn up to 46 semester credit hours of advanced standing in the BSRS program.

The department also includes the country’s first-of-its-kind Master of Science in Radiologic Science (MSRS) program. With this successful infrastructure, the university is uniquely aligned to provide the advanced academic program and Radiologist-directed clinical preceptorships required to prepare experienced and certified radiographers for this new role as RAs.

The MSU MSRS program, including the RA major, is be a “hybrid distance education” program, allowing students the benefits of clinical practice where it is most needed (off-campus) as well as the benefits of periodic face-to-face networking with other students and with faculty during on-campus seminars.
