Mammograms are low-dose x-rays of the breast that have been used for screening since the s. The breast is briefly squeezed compressed in two different positions and x-rays of the breast are taken.

What is Tomosynthesis Mammography? Breast tomosynthesis, also called three-dimensional 3-D mammography and digital breast tomosynthesis DBTis an advanced form of breast imaging, or mammography, that uses a low-dose x-ray system and computer reconstructions to create three-dimensional images of the breasts.

Breast tomosynthesis aids in the early detection and diagnosis of breast disease. A good analogy for 3D Mammography is like thinking of the pages in a book. If you look down at the cover you cannot see all of the pages — but when you open it up, you can go through the entire book page-by-page to see everything between the covers.

Very low X-ray energy is used during the screening examination so your radiation exposure is below the FDA guidelines. Clinically Proven to Deliver a More Comfortable Mammogram Compared to Standard Compression With pain being the number one complaint during mammograms, this fear of pain prevents many women from making regular breast imaging appointments a priority.

Not only can this have a negative impact on patient volume and satisfaction scores, but it can put women at risk of a cancer being missed, or diagnosed at a more advanced stage. What to expect during your exam A 3D mammography 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. A 3D mammography exam may be used as a screening tool in conjunction with a traditional digital mammogram or may be used by itself for a diagnostic mammogram.

During the 3D mammography part of the exam, the X-ray arm sweeps in A slight arc over the breast, taking multiple breast images in just seconds. Your doctor is then able to view your breast tissue in one millimeter layers.

There is no additional compression required with 3D mammography, and It only takes a few seconds longer for each view. The technologist will view the images at their computer workstation to ensure they have captured adequate images for review by a radiologist, who studies them and reports results to either your physician or directly to you.

Screening for breast cancer Doctors and scientists agree that early detection is the best defense against breast cancer.

Successful treatment and survival rates for breast cancers. If we find breast cancer early, before it has spread to lymph nodes, the five-year survival rate is almost percent. Until now, the best way to do that has been with digital mammography.

While digital mammography is still one of the most advanced technologies available today, it is only a 2-dimensional picture of the breast. The breast is a 3-dimensional object composed of different structures, such as blood vessels, milk ducts, fat, and ligaments.

All of these structures, which are located at different heights within the breast, can overlap and cause confusion when viewed as a 2-dimensional, flat image.

This confusion of overlapping tissue is a leading reason why small breast cancers may be missed and normal tissue may appear abnormal, leading to unnecessary call backs. Hologic- a world leader in digital mammography- has developed a new technology called 3D mammography also called breast tomosynthesiswhich Has been shown in clinical studies to be superior to digital mammography.The same machines are used for both types of mammograms.

A New Type of Digital Test: 3D Mammography

However, diagnostic mammography takes longer to perform than screening mammography and the total dose of radiation is higher because more x-ray images are needed to obtain views of the breast from several angles. Tomosynthesis, also digital tomosynthesis, is a method for performing high-resolution limited-angle tomography at radiation dose levels comparable with projectional radiography.

It has been studied for a variety of clinical applications, including vascular imaging, dental imaging, orthopedic imaging, mammographic imaging, musculoskeletal imaging, and chest imaging.

Recorded on Thursday, June 9, A certified one-hour live webinar for radiologists, radiologic technologists, and other healthcare professionals who care for patients with breast disease.

It takes about four seconds to obtain an image, just a little bit longer than a digital mammogram. 3-D mammography produces more images, so it does take radiologists a little longer to read than a single digital mammography image, but the original procedure is much the same. Digital Breast Tomosynthesis Seminars Satisfy the 8 hour requirement mandated by the MQSA to perform Breast Tomosynthesis in a Breast Imaging facility.

Tomosynthesis is used in 3D mammography in order to create a three dimensional image of breast tissue for better examination.
