Special Techniques in Mammography

Conventional film-screen mammography has proven to be a highly effective procedure for the diagnosis of a variety of breast diseases. However, there are several specific factors that limit image quality and the ultimate sensitivity of the examination. In many instances, the objects (calcifications, soft-tissue masses, etc.) associated with pathologic processes produce low-contrast images which might be near the threshold of visibility. Therefore, any modification of the procedure that can increase object contrast has the potential of increasing examination sensitivity.
