Background
This educational exhibit aims to review the history of mammography and its evolution to the present day. Breast imaging is a rapidly advancing area of radiology with an interesting history, the technology of which has relevance to all radiology trainees and practicing physicians.

Educational Goals / Teaching Points
The goals of this educational abstract are to describe the key historical events and advancements in technologies important to the field of mammography.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The origins of mammography begin in the early 20th century when surgeon Albert Salomon reported on his use of radiography of mastectomy specimens to demonstrate tumor local and nodal spread. The 1930s marked the first report of in vivo mammography and the first classification of benign and malignant breast disease by radiographic diagnosis. In 1949, Raul Leborgne first reported the significant association of radiographically detectable microcalcifications and carcinoma and recognized the importance of compression. In 1960, a reproducible technique by Robert L. Egan, jumpstarted widespread use. In 1963, Egan’s technique was shown to produce sufficient quality images allowing diagnosis of benign and malignant lesions, and that the modality could be used to screen for cancer in asymptomatic patients. The advent of needle localization, xeroradiographic images, magnification, oblique and views, and the first dedicated mammography unit, the Senographe would come in the 1960s and 70s. The rise of the screening mammogram in the 1980s led to the standardization of reporting through the Breast Imaging Reporting and Data System. Digital mammography emerged in the 1990s and gained FDA approval in 2000. Computer-aided detection (CAD) and contrast-enhanced and digital tomosynthesis are some of the latest developments in mammography.

Conclusion
Mammography has proven itself a valuable technology and key to early detection of breast cancer and reduction in mortality. Many steps along its interesting path have advanced the modality to the current day, creating momentum for further diagnostic and screening developments to come.
