3-D digital mammography is a revolutionary new breast imaging exam that improves the accuracy of mammography. In women having screening, 3-D digital mammography may be done along with a traditional 2-D digital mammography exam. Sometimes, 3-D mammography may be used to evaluate an abnormality like a breast lump. The 3-D mammogram is very similar to a 2-D mammogram. However, with 3-D mammography the X-ray tube moves and a series of mini X-ray exposures are obtained, creating a digital data set, which is then reconstructed into 1 millimeter thick slices or layers. The radiologist views each individual layer of the breast rather than a shadow of the entire breast. As a result, radiologists can detect breast cancer that was hidden by overlying tissue and that may mimic cancer and lead to a false alarm or unnecessary callback.
Benefits of 3-D mammography include:
Earlier detection of breast cancers that may otherwise be hidden by overlying tissue.
Greater accuracy in identifying the shape and location of abnormalities.
Fewer callbacks and helps distinguish harmless abnormalities from real cancers.
The 3-D mammography exams are recommended once you have discussed with your provider that the exam best meets your personal needs. 3-D mammography is offered at our Lebanon, Manchester and Nashua locations. Diagnostic breast biopsies for 3-D mammography can be performed at our Lebanon location.
