3D Mammography, or Tomography, helps detect breast issues earlier. This is a technique that provides three dimensional images of the breast and offers incredibly sharp images of the breast, so doctors can more accurately identify even the smallest abnormalities for a quicker diagnosis.
Benefits of 3D Mammography
Conventional Mammography shows your breast tissue in one flat image, but tomography creates a 3D image of your breast tissue in one millimeter slices. The radiologist can scroll through the images like pages of a book and see greater detail. Benefits include:
- Detection and review of abnormalities missed in 2D mammography
- Better understanding of overlapping breast tissue, which sometimes causes normal tissue to look abnormal in a 2D image.
- Lower chance that your doctor will call you back for a “second look”.
- Allows for quicker evaluation
How 3D Mammography Works
3D Mammography is performed at the same time as the standard 2D mammogram. No additional compression is required, and it takes just a few more seconds for each view. During the 3D part of the exam, the X-ray arm sweeps over your breast, taking multiple images. As with traditional mammograms, 3D mammograms use only very low X-ray energy.
