Primary Outcome Measures:
  • 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.
