3-D Helps More Accurate Breast Cancer Diagnosis
By Robin Wulffson MD for eMaxHealth.com
A new study has reported that three dimensional (3D) mammography, also known as tomosynthesis, significantly increases diagnostic accuracy, compared to standard digital mammography. In addition, it significantly reduces recall rates for non-cancer cases. Researchers affiliated with the Avon Comprehensive Breast Center, Massachusetts General Hospital (Boston, Massachusetts) published their findings online on November 20 in the journal Radiology.
In contrast to conventional mammography, which involves two X-ray images of each breast, tomosynthesis captures multiple images from different angles. These images are then used to make a 3D reconstruction of the breast. The researchers designed a study to compare radiologists’ diagnostic accuracy and recall rates for breast tomosynthesis combined with digital mammography versus digital mammography alone.
