3D Mammography
3D mammography, or tomosynthesis, is a breast imaging test that combines multiple breast X-rays to create a three-dimensional image of the breast.
3D mammograms provide a much more detailed cross-sectional image than 2D mammograms and are performed on the standard mammogram machine. This technique allows for a layered or sliced breast tissue acquisition of images. There is a minimal change in radiation dose for the patient.
For women with dense breast tissue, this form of imaging has undoubtably improved the peace of mind for both radiologist and patient.
Benefits of 3D Mammography
Here are the top benefits of 3D mammography / tomosynthesis:
- The technology is more sensitive with detections of breast cancer.
- Fewer recalls for patients especially regarding further biopsies.
- Less compressing or ‘squashing’ of the breast thereby reducing discomfort.
How to prepare for a 3d mammogram
To prepare for your 3D mammogram:
- Bring your prior mammogram images/records with you.
- Schedule a test for a time when your breasts aren’t likely to be tender or swollen.
- Try go to the same facility every time to ensure your mammograms can easily be compared from year to year.
- Bring a list of the places and dates of previous mammograms, biopsies, and any other breast procedures you’ve had before.
3D Mammography FAQs
Here are the answers to the most frequently asked questions around 3D Mammography:
How often do you need a 3D mammogram?
It is suggested that all women over the age of 40 undergo yearly 3D mammography breast screening. Women with a higher-than-average risk of breast cancer should have yearly mammograms from the age of 35.
How long does a 3D mammogram take?
A 3D mammogram is a relatively quick procedure. Typically, the process takes about 20-40 minutes. The time may vary depending on whether or not the image needs to be retaken if the quality is not good enough.
What should you not do before a 3D mammogram?
Avoid using deodorants, powders, anti-perspirants, creams, or perfumes under your arms or on your breasts prior to a mammogram. The metallic particles in deodorants and powders can interfere with the imaging.
