tomosynthesis:

see mammographymammography,
diagnostic procedure that uses low-dose X rays to detect abnormalities in the breasts. Tomosynthesis, also known as 3D mammography, is form of mammography that combines X-ray images taken at multiple angles to produce a single three-dimensional image.

The Dynamic MUSICA includes MUSICA Digital TomoSynthesis software, which powers the tomosynthesis reconstruction, automatically presenting images with optimal contrast and providing consistent image quality across the individual slices and images.
"The difference is not in how the images are taken, but in the results that the 3D tomosynthesis provides - we can detect breast cancers that lie deep in the breast tissues and provide a far better option for women with dense breasts."
(1) Additionally, there is no requirement for triangulation of the mammographic abnormality via stereo pair images as the depth is calculated by the system automatically when localizing an abnormality on scout tomosynthesis images (Figures 5-6).
During this period, 43,221 mammography and 16,254 mammography and tomosynthesis examinations were performed at the breast imaging unit.
"Tomosynthesis and digital mammography is much more sensitive than digital mammography," Pattacini said in a statement.
One of the main disadvantages of tomosynthesis is the long acquisition time which makes it very susceptible to motion degradation of image quality.
Some studies have found tomosynthesis detects more cancer with fewer false alarms; they're often advertised as particularly useful for younger women's dense breasts.
Digital breast tomosynthesis (DBT) can involve simultaneous acquisition of a conventional 2D mammogram along with a series of images to create a 3D image.
For example, the Tomosynthesis Ma nomographic Imaging Screening Trial (TMIST) will compare conventional (2-D) mammography and 3-D mammography (tomosynthesis) to see which is better at early-stage detection of aggressive types of breast cancer.

Not only does Sectra have a proven track record of flawlessly connecting specialists, they also have excellent tools for reading 3D tomosynthesis. I have made it a priority to invest in the best technology available for my practice and Sectra was a logical extension of that decision, says Andrea Woodroof, MD and founder of Kentucky Breast Care.
