3D Tomosynthesis Mammography

Screening for Breast Cancer

Early detection is the best defense against breast cancer. If cancer is discovered in its earliest stages, the chances of surviving are good. Until now, the best method of early detection has been digital mammography, using a specially designed camera and a computer to produce an image displayed on a high-resolution monitor. While digital mammography is still one of the most advanced technologies available, it is only a two-dimensional picture of the breast. Since the breast is composed of pockets of dense tissue surrounded by fat, the overlapping tissue in a digital image makes it difficult to see tiny spots called microcalcifications, and other subtle signs of early cancer.

3D Mammogram - Breast Tomosynthesis

Breast tomosynthesis allows radiologists to evaluate breast tissue one layer at a time. This exciting new technology has recently been FDA approved and is now available at the Shimberg Breast Center. Breast tomosynthesis may be used in conjunction with traditional digital mammography as part of your annual screening mammogram. Very low X-ray energy is used during the screening examination so your radiation experience is safely below the American College of Radiology (ACR) guidelines: the equivalent of flying from Los Angeles to New York. Using breast tomosynthesis and digital mammography together for screening has been proven to reduce return appointments.

What is Breast Tomosynthesis?

Breast tomosynthesis converts digital breast images into a stack of very thin layers or “slices” – building what is essentially a three-dimensional mammogram. During the tomosynthesis part of the exam, the X-ray arm sweeps in a slight arc over the breast, taking multiple breast images in just seconds. A computer then produces a 3D image of your breast tissue in one millimeter layers. Radiologists can now see breast tissue in a more detailed way. Instead of viewing your breast tissue in a flat image, the tissue can be examined a millimeter at a time and fine details are more clearly visible.

What to Expect During Your Exam

A tomosynthesis exam is very similar to a traditional mammogram. Just as with a digital mammogram, the technologist will position you, compress your breast under a paddle and take images from different angles. During the tomosynthesis portion of the exam, your breast will be under compression while the X-ray arm of the mammography machine makes a quick arc over the breast, taking a series of images from a number of angles. This takes only a few seconds and all of the images are viewed by the technologist to ensure they have captured adequate images for review by a radiologist.
The whole procedure takes approximately the same amount of time as that of a digital mammogram alone. The technologist sends your images electronically to the radiologist, who studies them and reports the results to your physician.

Early Detection Is the Key

Our primary goal has always been to deliver the highest quality care to our patients, so we have added breast tomosynthesis to our breast health services. The breast tomosynthesis system was selected because we believe that it offers the best technology available for early detection.
