3D mammography — also called digital breast tomosynthesis (DBT) — captures multiple thin image slices of the breast from different angles, letting radiologists view tissue in three dimensions instead of a single flat 2D image. It finds more cancers in dense tissue and produces fewer false alarms.

How is 3D mammography better than 2D?
In a conventional 2D mammogram, overlapping tissue can hide a cancer or mimic one. Tomosynthesis separates the tissue into thin slices, so radiologists can look through it layer by layer.
- Enhanced detection, particularly in dense breast tissue
- Fewer false positives and unnecessary callbacks
- Better distinction between benign and malignant lesions
- A patient experience similar to a traditional mammogram
What happens during the exam?
The appointment takes approximately 20 to 30 minutes. You will remove upper clothing, and a technologist positions the breast to capture images from multiple angles. A radiologist analyzes the results, typically within a few days.
MRI Associates performs 3D mammography on the Fujifilm ASPIRE Cristalle, a system engineered for both image quality and comfort.
Why is my breast compressed?
Each breast is imaged in two positions, and a paddle spreads the tissue to an even thickness. That is what makes very small abnormalities visible — and because the tissue is thinner, the exam needs significantly less X-ray to produce a clearer picture. Compression should feel firm, not painful. Tell your technologist if it does and they will adjust. It is not harmful, and it lasts only seconds per image.
When should screening start?
MRI Associates recommends that women begin annual screening mammograms by age 40, or earlier if certain risk factors are present. Your individual risk factors and family history should guide that conversation with your physician. Mammograms find many breast cancers far earlier than a self-exam or a physical exam can — but self-exams and clinical breast exams still matter, and should continue alongside your annual screening.
How will I get my results — and what if you call me back?
Most patients receive a written report within a few days; for most patients that report is required by law. Sometimes we ask you to come back for a few additional views. That is common, and the great majority of callbacks turn out to be normal — the extra images simply clarify an area that overlapping tissue made hard to read.
If you came in with a symptom such as a lump or thickening, your exam is a diagnostic mammogram rather than a screening one. It is tailored to that concern and may include spot or magnification views of the area.
How do I prepare?
Skip deodorant, lotion, and powder on exam day. Wear a two-piece outfit. Results in a few days.

Where can I get this exam?
3D Mammography is available at three of our centers — Palm Harbor MRI, Winter Haven MRI and Brandon MRI. One call reaches every location — we will schedule you at whichever has the soonest opening, usually the same week.
