Arm Intervention/treatment
Experimental: 1
Subjects will undergo a 3D breast Tomosynthesis imaging scan. This is a one time breast imaging scan will last approximately 15 minutes.
Procedure: Breast Tomosynthesis
3D breast imaging

Primary Outcome Measures :
  1. Measure of digital tomosynthesis and digital mammography test performance. [ Time Frame: 3 weeks ]
    Interest of sensitivity, specificity and area under region of concern curve for malignant mass detection. During review, the number of masses and location and size of each mass will be recorded. An additional estimate of probability of malignancy will be recorded for each image sets.
