Digital Breast Tomosynthesis

Digital breast tomosynthesis boosts radiologists' cancer detection rates compared to digital mammography alone. The researchers conducted a multicenter, multi-reader study to evaluate reader performance with tomosynthesis.
It's done like a regular mammogram and still involves compressing the breast. But it takes a 3-D view with a CT scan in an arc around the breast. The machines are expensive, and as with many new techniques, testing will be expensive too. It only takes a few seconds to do the tomosynthesis part of the exam, but then the machine will also take a regular mammogram.
