ACR Fellowship

One of the highest honors the ACR can bestow on a radiologist, radiation oncologist or medical physicist is recognition as a fellow of the American College of Radiology.  ACR Fellows demonstrate a history of service to the College, organized radiology, teaching, or research.  Approximately 12% of ACR members achieve this distinction.


In 1923 when the College was first conceived, its founders intended it to be a small elite group of fellows. In 1924, the founders inducted seven fellows at the first convocation and the ACR bylaws approved that year limited membership in the future to 100, of which not more that five new fellows would be accepted annually. Although an extremely prestigious society, its size limited the amount of work it was able to accomplish. By 1931 the College was being encouraged to enlarge its membership in order to expand its projects. In 1935 the new category of member was created for diplomates of the American Board of Radiology and the induction of fellows was retained for those members who had attained eminence in the specialty.

How Does Someone Become an ACR Fellow?
The requirements for fellowship change over the years as the ACR Board of Chancellors continues to clarify and redefine them. It is by these criteria that the Committee on Fellowship Credentials measures each nominee's credentials and makes its recommendations to the board for approval, deferral or rejection.  Please see the ACR Fellowship Guide below for more details about the nomination process.
