Centennial Medical Center Kicks off Breast Cancer Awareness Month with the Latest in Breast Cancer Imaging Technology
October 13, 2011
Nashville, Tenn. (October 07, 2011) – Women who undergo mammograms at Centennial Medical Center will now have the latest 3-D imaging technology available to them. Centennial is one of the first breast centers in the United States and the first in Middle Tennessee to offer breast imaging with digital tomosynthesis, or 3-D mammography, with the Hologic Selenia Dimensions-3-D.
Centennial Medical Center began conducting 3-D imaging trials in April and now offers this superior imaging technology to a range of women meeting specific criteria. The use of mammography, and in particular 3-D mammography, greatly enhances the ability to detect breast cancer at an early stage, when it’s most treatable.
“The beauty of 3-D breast imaging is that it removes one of mammography’s greatest limitations – the superimposition of tissue,” said Patricia Tepper, M.D., Medical Director of the Centennial Breast Center. “Normal overlapping tissue can obscure a cancer, or conversely, create a false appearance of abnormality where none exists. This is the greatest source of false negatives and false positives in 2-D imaging, but with tomosynthesis, we can significantly increase our accuracy and reduce the incidence of unnecessary diagnostic intervention.”
Breast tomosynthesis, which received FDA approval earlier this year, obtains images on the same type of equipment as conventional 2-D images and often during the same compression. Women who have an abnormal finding on their traditional mammogram can then receive a tomosynthesis scan at Centennial Medical Center to further investigate the abnormalities on the initial mammogram. The high quality images produced by tomosynthesis scans can greatly reduce the call back rate for women with abnormalities found on their mammogram, reducing the inconvenience of making multiple visits to the hospital.
Breast tomosynthesis is also revolutionizing the practice of mammography through its ability to yield high-quality images with low dosages of radiation. During the scan, the camera moves in an arc, obtaining low-dose images every 15 degrees. The computer then reconstructs the data in 1 millimeter slices, much like a CT or MRI. The images are obtained in the same four projections as a standard mammogram and only take an additional four seconds per view. The scans also emit a radiation dose significantly lower than the FDA’s maximum allowable for a screening mammogram study, which is equal to the same radiation dose you would receive from living in Denver for three months due to increased radiation exposure from the higher elevation.
“By offering women the latest technology in mammography, Centennial Medical Center hopes to increase the number of women who can be effectively screened, said Wayne Reid, Vice President of Imaging at Centennial Medical Center. “Breast cancer is the second leading cause of cancer death among women, exceeded only by lung cancer. That’s why early detection is so critical to increasing a woman’s chances of survival. With breast tomosynthesis, Centennial is now able to provide women in Middle Tennessee with a powerful tool in the fight against breast cancer.”
