What is 3D Mammography?
Mammography What is Mammography? Mammography, also known as a mammogram, is the examination of the breast using x-rays. Mammography is considered the most effective tool for early breast tumor detection. Most medical experts agree that successful treatment of breast cancer often is linked to early diagnosis.
Mammography plays a central part in early detection of breast cancers because it can show changes in the breast up to two years before a patient or physician can feel them.
Our Practice uses digital mammography. Also known as a full-field digital mammography, digital mammography allows the radiologist to alter the orientation, magnification, brightness and contrast to produce images of the breast that can be seen on a computer screen.
Computer-aided detection, or CAD, uses a digitized mammographic image to search for abnormal areas of density, mass, or calcification that may indicate the presence of cancer. The CAD system highlights these areas on the images, alerting the need for further analysis.
What are the advantages of digital mammography and computer-aided detection? Compared to conventional mammography that takes minutes, digital mammography images are taken in less than a minute. The superior contrast resolution of digital mammography and its ability to manipulate images make for more accurate detection of breast cancers.
Computer-aided detection, or CAD, obtains a second, computerized reading in the hope of finding more cancers or more accurately gauging signs of malignancy.
Digital mammograms can be archived in various ways and easily retrieved, and copied. How often should I have a mammogram? Current guidelines from the U. The National Cancer Institute NCI recommends that women who have had breast cancer and those who are at increased risk due to a genetic history of breast cancer should seek expert medical advice about whether they should begin screening before age 40 and about the frequency of screening.
When should I schedule my mammogram? Before scheduling a mammogram, you should discuss problems in your breasts with your doctor. In addition, inform your doctor of hormone use, any prior surgeries, and family or personal history of breast cancer.
Generally, the best time is one week following your period. Do not schedule your mammogram for the week before your period if your breasts are usually tender during this time. Always inform your x-ray technologist if there is any possibility that you are pregnant.
How should I prepare for a mammogram? On the day of the exam: You will be given a gown that opens in the front. What should I expect during this exam? To image your breast, an x-ray technician will position you near the machine and your breast will be placed on a platform and compressed with a paddle.
Breast compression is necessary in order to: Even out the breast thickness - so that all of the tissue can be visualized. Spread out the tissue - so that small abnormalities won't be obscured. Allow use of a lower x-ray dose. Hold the breast still - to eliminate blurring of the image caused by motion.
Reduce x-ray scatter - to increase picture sharpness. The technologist will go behind a glass shield while making the x-ray exposure. You will be asked to change positions slightly between views.
The process is repeated for the other breast. Routine views are a top-to-bottom and side view. What will I experience during the procedure? The exam takes about a half an hour.Free Essay: Mammography Breast cancer is a common malignancy diagnosed in women.

Three-dimensional mammography (also called digital breast tomosynthesis) creates a three-dimensional picture of the breast using x-rays.
Several low-dose images from different angles around the breast are used to create the 3D picture. The Best Breast Cancer Screening Tests. 5 More Reasons Not to Get a Mammogram. by Christiane Northrup, M.D. Mammography uses X-rays to create images of the breast. These images are called mammograms.

Like other X-ray images, mammograms appear in shades of black, gray and white, depending on the density of the tissue (see images below).. Very dense tissue, like bone, shows up as white on an X-ray. Breast cancer screening most often includes mammography but can also include ultrasound, MRI, and other tests.
