Emergency radiology, as a clinical area of interest, existed well before emergency medicine was regarded as a distinct specialty. However, as with the clinical specialty, emergency radiology was felt to be a concatenation of radiology disciplines, generally with musculoskeletal (plain radiographic) imaging being the greatest center of gravity. Even during the adolescence of this field, radiologists were still challenged to determine who would read advanced imaging studies (ie, ultrasound, computed tomography [CT], magnetic resonance imaging, nuclear medicine) and when. As the clinical field reached maturity, so did emergency radiology, accompanied by a large array of excellent textbooks, review manuals, and pictorial essays.
