SOCIETY OF BREAST IMAGING/AMERICAN COLLEGE OF RADIOLOGY
BREAST IMAGING TRAINING CURRICULUM
 
 
The breast imaging training curriculum has been designed principally [a] to provide guidance to academic chairs, residency program directors, and academic section chiefs in assessing and improving their residency and fellowship training programs, and [b] to indicate to residents and breast imaging fellows the topics they need to learn and the experience they should try to acquire during their training. Radiologists already in practice also may find the curriculum useful in outlining the material they need to know to remain up to date in the practice of breast imaging.
 
The curriculum consists of bulleted lists, in outline format, covering many areas pertinent to breast imaging practice. These revised lists have been shortened somewhat from those provided in the initial curriculum in order to produce a more concise document. It is assumed that the academic section chiefs who are directly responsible for providing breast imaging training will expand and elaborate the abbreviated list items, as appropriate. Several of the listed items involve aspects of breast imaging practice that are not universally available in either academic or community practice, for example full-field digital mammography, computer aided detection (CAD), and breast magnetic resonance imaging (MRI). If a training program finds it impractical to provide hands-on experience with a given list item, either on-site or at a cooperating neighbor institution, then instruction should be provided in lecture, conference, syllabus, videotape, or other format. The curriculum also includes several specific documents with which residents and fellows should become familiar, for example the most recent edition of the Breast Imaging Data and Reporting System (BI-RADS) of the American College of Radiology (ACR) (2). The selection of specific textbooks and other learning materials is left to the discretion of both trainers and trainees, with the understanding that learning is most effective when a variety of educational materials are studied. The curriculum omits recommendations concerning the number of specific breast imaging examinations and procedures that residents and fellows should perform during their training. Clearly more is better, but local institutional conditions (for example, several residents and fellows on service simultaneously) may preclude the achievement of a specific target number for a given infrequently performed procedure, especially as concerns every resident in training. Academic section chiefs should consider the volume requirements for initial and continuing experience of Food and Drug Administration (FDA) regulations under the Mammography Quality Standards Act (MQSA) and the several ACR Accreditation Programs as desirable minimum volume goals for their resident trainees, and to expect their fellow trainees to far exceed these volume goals.
 
Evaluation of resident proficiency should follow the general categories and evaluation methodologies outlined by the Residency Review Committee (RRC) for Diagnostic Radiology of the Accreditation Council for Graduate Medical Education (ACGME). Specifically, the RRC has defined six general competency areas that are critically important in the teaching and practice of diagnostic radiology. We therefore have adapted these competencies for the purposes of evaluation of the resident curriculum in breast imaging.
 
The ultimate goal of a residency training program in breast imaging should be for resident graduates to be fully prepared to assume the role of interpreting physician in any breast imaging facility, without the need for additional training. Residency training must involve a minimum of 12 full-time equivalent weeks of clinical training in breast imaging during the entire 4-year residency. It is recommended that the initial month of breast imaging training be given in the first or second year of residency, to expose residents to the practice of breast imaging before they are expected to make a subspecialty career choice. It also is recommended that the last month of breast imaging training be given in the last 6 months of residency, because in case Board certification is not achieved by the end of residency, the MQSA initial-experience requirement for direct supervision of at least 240 mammography interpretations must be met within 6 months (rather than 2 years) of beginning independent interpretation of mammography examinations.
 
The ultimate goal of a fellowship program in breast imaging should be for fellow graduates to be fully prepared to assume the role of lead interpreting physician in any breast imaging facility, without the need for additional training. To this end, a breast imaging fellowship should involve a minimum of 6 full-time equivalent months of training after completion of residency; 12 months is recommended.
 
Breast imaging has undergone considerable growth and change in recent years, and this trend is expected to continue. Therefore, the residency and fellowship training curriculum likely will require periodic additional updates.
