3D Mammography (Digital breast tomosynthesis)

What is 3D Mammography(Digital Breast Tomosynthesis)
3D Mammography is a revolutionary new screening and diagnostic tool designed for early breast cancer. It is approved for all women who would be undergoing a standard mammogram, in both the screening and diagnostic settings. 3D mammography take only 3.75 seconds for each view, like conventional 2D mammography.

How Does it work? 
3D mammogram captures multiple slices of the breast, all at different angles. Multiple images of the breast are then reconstructed into 1mm thin slice of the breast. The radiologist is then able to review the reconstructed images, one thin slice at a time. With this technology, overlapping glandular tissue can be removed and cancers can be more accurately diagnosed. 

Higher Accuracy

• 51% increase in cancer detection
  
• Overlapping glandular tissue can be removed in 3D mammography

Better Characterisation

• Better visualisation of mass, distortion and asymmetric density
• Better delineation of disease extent

Lower Recall

• Less additional view or compression

More Comfortable

• Less compression force in 3D mammogram does not affect image quality
• With C-ViewTM technology, compression time is much shorter
