3D Mammography is Here
3D Mammography Improves Breast Cancer Detection
3D mammography exams are clinically proven to increase better screening and reduce patient call backs
The Beth Israel Deaconess Hospital-Plymouth Breast Center now offers 3D mammography.i Utilizing advanced breast tomosynthesis or 3D technology, 3D exams are clinically proven to significantly increase the detection of breast cancers, while simultaneously decreasing the number of women asked to return for additional testing compared to 2D or digital mammography.
BID-Plymouth is committed to the fight against breast cancer. In offering the 3D exam, we provide a more accurate tool for breast cancer screening. “From the beginning the Breast Center has been committed to providing exceptional care to women on the south shore and Cape Cod and we are so excited to continue to do so by offering 3D mammography,” says radiologist and Director of Breast Imaging, Colleen Whitecar, MD.
In conventional 2D mammography, overlapping tissue is a leading reason why small breast cancers may be missed and normal tissue may appear abnormal, leading to unnecessary callbacks. A 3D exam includes a three-dimensional method of imaging that greatly reduces the tissue overlap effect.
A 3D exam includes both 2D images and 3D scans. During the 3D portion of the exam, an X-ray arm sweeps in a slight arc over the breast, taking multiple images. A computer then converts the images into a stack of thin layers, allowing the radiologist to review the breast tissue one layer at a time. A 3D exam requires no additional compression and takes just a few seconds longer than a conventional 2D breast cancer screening exam.
3D exams are recommended for women of all ages and breast densities, and allow our radiologists to more effectively pinpoint the size, shape, and location of abnormalities. This leads to better detection and greater peace of mind for our patients.
Large clinical studies in the U.S. and Europe have demonstrated the positive benefits of a 3D mammography exam. The largest study to date on breast cancer screening using the 3D exam was published in the June 25, 2014 issue of the Journal of the American Medical Association (JAMA).ii Findings include:
- A 41% increase in the detection of invasive breast cancers.
- A 29% increase in the detection of all breast cancers.
- A 15% decrease in women recalled for additional imaging.
