Mammography & Breast Imaging in Dallas
Mammography (also known as a mammogram procedure) is an examination of the breast using low dose X-rays. Most medical experts agree that successful treatment of breast cancer is often linked to early diagnosis, and mammography is considered the most effective tool for early breast tumor detection. It plays a central role in the early detection of breast cancer, as it can show changes in the breast up to two years before a patient or physician can feel them.
Offering Digital Mammography and 3D Mammography
Southwest Diagnostic Imaging Center has the capability to perform both full-field digital mammography and 3D Tomosynthesis mammography.
Digital mammography, or 2D mammography, uses detectors that convert X-rays into electrical signals. These electrical signals produce images of the breast that can be seen on a computer screen. The radiologist is able to change the magnification, orientation, brightness, and contrast of these images.
3D mammography, or Tomosynthesis mammography, is an advanced form of breast imaging where images are acquired in 1 mm “slices” which are then reconstructed into a 3D image. The acquisition of many images in different angles provides more information per mammogram for radiologist interpretation. The positioning, compression, and radiation dose are equivalent to that of a traditional 2D mammogram.
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 radiologists to the need for further analysis.
Advantages of 3D Mammography and Computer-aided Detection
- 3D mammography may reduce the need for callback imaging in women with dense breast tissue
- 3D mammography may find abnormalities that might otherwise be obscured in dense breast tissue on a 2D mammogram
- Computer-aided detection, or CAD, obtains a second, computerized reading, with the goal of finding more cancers or more accurately gauging signs of malignancy
How Often Should You Have a Mammogram
Current guidelines from the U.S. Department of Health and Human Services (HHS), American Medical Association (AMA), and the American College of Radiology (ACR) recommend a mammography screening every year for women, beginning at age 40.
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 frequency of screening and whether they should begin screening before age 40.
When To Schedule a Mammogram
Before scheduling a mammogram online, you should discuss problems with your breasts with your doctor. Generally, the best time to schedule your exam 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 mammography technologist if there is any possibility that you are pregnant.
What To Expect During a Mammogram
A licensed mammography technologist will perform your exam. Your breast will be placed on a special platform on the mammography unit and compressed with a clear plastic paddle. The technologist will gradually compress your breast. 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 will not 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.
You will be positioned for two projections of each breast. Standard views are top to bottom and an oblique, or side view. Learn how you can prepare for your mammogram.
What You Will Experience During a Mammogram
The exam takes about fifteen minutes to half an hour, depending on the number of images needed. You will feel pressure on the breast as it is squeezed by the compression paddle. Some women with sensitive breasts may experience some minor discomfort. Be sure to inform the technologist if pain occurs as compression is increased. If discomfort is significant, less compression will be used.
