  • Breast Cancer Case

  • Of the three small masses, which one is malignant?

  • Please note: All cases underwent a de-identification process when received, thus no history or content can be provided regarding the patient.

If you selected Case #3, then you are correct!

The other two cases were benign.

Discussion

Several recent studies have shown that AI-CAD can increase the diagnostic accuracy of breast cancer without increasing false-positive rate which was a vulnerability of C-CAD.

Since the false-positivity rate can cause significant fatigue for readers as well as delays in reading time, it is important to reduce the false positives as much as to increase the breast cancer detection rate in order to be used efficiently as an aid.

According to a study by the Korean Society for Breast Screening, AI-CAD can contribute to increase the efficiency in image interpretation by significantly decreasing false-positive rate compared with C-CAD.


94% reduction in false-positive rate
