3-D breast tomosynthesis uses high-powered computing to convert digital breast images into a stack of very thin layers or "slices" - building what is essentially a 3-dimensional mammogram.
The 3-D images allow doctors to examine breast tissue one layer at a time. Very low X-ray energy is used during the screening examination - which takes about 10 seconds to acquire - so a patient’s radiation exposure is safely below the American College of Radiology (ACR) guidelines.
With 3-D images, St. Clair Hospital diagnostic radiologists can see tissue detail in a way never before possible. Instead of viewing all of the complexities of a woman’s breast tissue in a flat 2-D image, a radiologist can examine the tissue a millimeter at a time. Fine details are more clearly visible, no longer hidden by the tissue above and below.
When used together, 3-D breast tomosynthesis and digital mammography have been proven to reduce "call-backs," scenarios in which patients are asked to return for follow-up examinations to rule out any suspicious areas. The use of 3-D tomosynthesis has proven particularly beneficial in woman with dense breast tissue and has reduced the number of unnecessary invasive diagnostic procedures.
