ABOUT MAMMOGRAPHY AND TOMOSYNTHESIS
Digital Breast Tomosynthesis (also known as 3D mammography) was approved by the FDA in February 2011. It is a modification of the current 2D (digital) mammography that, instead, produces a 3D image of the breast.
Modified X-ray systems are most commonly used for tomosynthesis
Dr. Skaane and colleagues have been studying tomosynthesis as a promising breast cancer screening option that addresses some of the limitations of mammography by providing 3-D views of the breast.
"Tomosynthesis could be regarded as an improvement of mammography and would be much easier than MRI or ultrasound to implement in organized screening programs," Dr. Skaane said. "So the intention of our study was to see if tomosynthesis really would significantly increase the cancer detection rate in a population-based mammography screening program."

Tomosynthesis creates multiple images or "slices" that step through the breast tissue. This allows the radiologist to see greater detail and helps reduce the impact of overlapping breast tissue. The process is performed at the same time as a normal mammogram, on the same scanner, with no noticeable differences in the experience or time expended for the patient.
The value of X‑ray digital tomosynthesis in the …
This image depicts a tomosynthesis experience from the patient's point of view. A 3D mammogram exam is very similar to a 2D mammogram. In fact, both images are taken at the same time, on the same scanner. And just as with a 2D digital mammogram, the technologist positions the patient, compresses their breast under a paddle and takes images from different angles. During the 3D portion of the exam, the machine's x-ray arm makes a quick arc over the breast, taking a series of images at a number of angles. Tomosynthesis adds no time to the exam, with the entire procedure taking approximately the same amount of time as that of a 2D mammogram.

This image illustrates the differences in 2D and 3D breast imaging. In the "conventional" 2D mammogram (pictured left), there is an apparent area of concern that may require additional studies, like another mammogram or a biopsy. Instead, looking at the same breast tissue in a succession of 3D images (pictured right), doctors can now see that the tissue is, in fact, normal breast tissue that was simply overlapping in the traditional mammogram, thus creating the illusion of an abnormality. In this scenario, the patient likely avoided a callback for an additional mammogram—and the anxiety that goes along with it—thanks to tomosynthesis technology.

Tomosynthesis is an optional service for the patient, which supplements the conventional mammographic images. While 2D digital mammography remains the gold standard for early detection 3D images can offer better visualization for radiologists who are helping certain groups of patients—particularly those with dense breasts, which is determined by a prior mammogram.
