Twenty of 64 were upgraded from M3 to tomosynthesis 4.The morphology of the lesions upgraded was spiculated 30/64, 7/64 distortions and 7/64 ill-defined densities.
The technique is the same as in screen-film mammography.
Adjustments can be made during the procedure, thus reducing the need to repeat mammograms and reducing the exposure to radiation.

A screening mammography is one of several tools that are used for early detection of breast cancer in asymptomatic women.Other screening tools include the clinical breast examination and breast self-examination.
