These two sites are managed by J. Keith Smith, MD, PhD, and all case material for the mammography section of the Teaching File is provided by Etta Pisano, MD, Chief of Breast Imaging and Professor of Radiology at UNC. Both sites provide the same mammography teaching cases which demonstrate various common findings. The UAB website allows the cases to be reviewed at random as "unknowns" so that users may render their own diagnosis. The cases can also be viewed by diagnosis.
