3-D Mammograms: What Does the Science Tell Us?
Screening mammography for breast cancer detection has been criticized for its high false positive rate. Recent advances in tomosynthesis provide 3-D breast images that bring another dimension to mammograms but with the drawback of additional radiation.
This blog comments on a recently published limited clinical study that shows a significant reduction in false positive rates using tomosynthesis-based 3-D mammograms. Besides the issue of whether the improvement in false positives is scalable, the concern over higher radiation exposure still remains. Perhaps a carefully designed clinical study on when tomosynthesis imaging of the breast should be done could be helpful in answering these questions, after additional expanded studies.
