3D Mammography at Methodist Germantown Breast Center
The Methodist Breast Center is one of the only facilities in Memphis to offer 3D breast tomosynthesis (DBT) for breast cancer diagnostic exams.
3D mammography helps detect breast cancer early. It offers incredibly sharp images of the breast, so doctors can accurately identify even the smallest abnormalities for a quicker diagnosis. If you qualify for diagnostic mammograms, you may opt for 3D mammography.

Benefits of 3D Mammography
Conventional mammography shows your breast tissue in one flat image, but tomosynthesis 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 of cancers missed in 2D mammography.
- Better understanding of overlapping breast tissue, which sometimes causes normal tissue to look abnormal in a 2D image. (See image)
- Lower chance that your doctor will call you back for a “second look.”
Above: A 2D mammogram appears to show an area of concern that may have required further study with another mammogram or a biopsy. The same breast tissue in 3D image slices reveals normal breast tissue that was overlapping in the 2D images—creating the illusion of an abnormal area. This patient likely avoided a callback thanks to the tomosynthesis exam technology.
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.
