The Breast Imaging Teaching Files are designed for the education of Radiology residents and fellows.  They are not meant to inform patients about treatments or management decisions.  The files were originally created by Katherine E. Dee, MD while she was a member of the faculty of the University of Washington Department of Radiology. A report describing this work was published in the journal Medical Education.  The cases and content are continuously updated to reflect changes in medical knowledge, imaging technology and clinical practice.  If you have any questions, please contact us.
