Choosing the Best Breast Screening:
2D Mammogram vs. 3D Mammogram
Facts About 2d Mammography
- A 2D mammogram is a low dose x-ray of the breast
- Only provides two or three standard images of the breast which can lead to overlapping and the need for additional images to be taken
- Slightly less radiation than a 3D mammogram but not significant
- 2 to 3 seconds shorter than 3D mammogram
Facts About 3D Mammography
- 3D mammography allows our Radiologists to view multiple images of breast tissue from different angles
- Process is performed at the same time as a traditional 2D mammogram and only take a few more seconds
- There is no additional compression required
- All women may benefit from 3D mammography
- Increased benefits for women with dense breast tissue
- Provides clearer images
- Increases earlier detection
- Greater accuracy
- Reduces callbacks and false positives
Women’s Imaging Services
Regarding the recent guidelines by the American Cancer Society regarding mammography screening, AAR strongly agrees with the recommendations of the American College of Radiology (ACR) and of the Society of Breast Imaging (SBI). In order to obtain the maximum benefit from screening mammography, AAR (along with the ACR and SBI) advises yearly screening, commencing at age 40. Starting screening at later ages or screening biennially for older individuals would result in delayed detection which may adversely affect mortality and morbidity from breast cancer. We firmly believe based on the evidence we see every day that screening mammography saves lives.

AAR offers the following mammography services at our Alexandria and Woodbridge imaging centers:
- 3D Digital Mammography with tomosynthesis
- Standard 2D digital mammography
Bone density, or DEXA, is a quick and noninvasive examination that uses a small dose of ionizing radiation to measure bone loss, diagnose osteoporosis and assess an individual’s risk for developing fractures. Patients should always inform their physician or technologist if they have recently had a barium examination, or have been injected with contrast material prior to the scheduled appointment. Patients should not take calcium supplements for 24 hours before the exam. Dexa is the established standard for measuring bone mineral density.

3D Digital Mammography with Tomosynthesis
Breast tomosynthesis, also known as 3D Mammography, is an advanced form of mammography that uses low dose x-rays and computer reconstruction to create 3D images of breast tissue. Conventional 2D mammography only take images from the top, bottom and sides of the breast and can cause overlapping breast tissue leading to additional images needed later.
3D mammography aids in some of the limitations of 2D standard mammography. With a 3D mammogram, the X-ray tube moves over the compressed breast tissue capturing multiple images from all angles of the breast. These 3D images aid in minimizing tissue overlap that can obscure hidden masses.
How do I prepare for my mammogram?
AAR recommends not wearing deodorant, using talcum powder or using lotion on your arms or breast on the day of your exam. Deodorant artifacts can be mistaken for calcium deposits on the mammogram, therefor we ask patients not to wear deodorant. AAR does provide deodorant wipes upon completion of the exam.
If you are a new patient to our facility, we ask that you obtain your prior mammogram and sonogram images as well as reports, and bring them with you the day of your exam. This will allow our radiologist to compare your prior exams with your current study.
C-View is the latest technology in women’s breast care and is now available at no additional cost to our patients.
How does it work? – Digital breast tomosynthesis (3D mammography) obtains multiple sliced images through the breast unlike conventional 2D mammography which obtains a single image of the breast. The addition of 3D mammography has resulted in an increase in breast cancer detection by 40%. Previously 3D images were obtained in addition to 2D images. With the addition of C-View technology which is now available at AAR, conventional 2D images are reconstructed from the 3D image set.
With C-View you get:
Faster examination times
Less motion artifacts
Lower radiation dosage
Increased patient comfort
Improved lesion detection
Types of Mammograms
A routine annual exam recommended for women who do not have breast symptoms. The aim of screening mammograms is to detect unsuspected breast cancers at any early stage when treatment is most effective.
A diagnostic mammogram is performed when a woman or heath care professional discovers a lump, tenderness, nipple discharge or skin changes. Diagnostic mammograms are also used after a patient has had suspicious results on a screening mammogram. Diagnostic mammograms are also performed when a short term follow up from a prior diagnostic mammogram is recommended, or if a patient has been previously treated for breast cancer.
A diagnostic mammogram can be interpreted a few ways:
- An area of concern on a screening mammogram is actually normal and no further evaluation is needed.
- An area of concern is not cancerous, but the radiologist recommends following the area with a four to six month diagnostic follow up.
- Area of concern that is suspicious for cancer and recommends a biopsy for confirmation.
When will I get my results?
The referring physician will receive a copy of the finalized report within 24 hours. Additionally, AAR offers patients the convenience of our patient portal system allowing patients access to their reports, online within 72 hours of their scheduled appointment.
Per MQSA guidelines, a letter with your results will be mailed to the home address on file within 7 days of the exam(s) performed.
