3D Mammography

3D mammography, also called digital breast tomosynthesis, uses an X-ray system to create a series of breast images from different angles. A computer combines these views into thin image layers that can be reviewed one at a time. This may make overlapping breast tissue easier to assess than a single flat image.

During the examination, each breast is placed between two plates for a short period while the X-ray arm moves in an arc. You need to remain still and may be asked to hold your breath briefly. The images are then assessed by a radiologist, often alongside earlier images or other breast imaging when available.

3D images can show more detail, but they cannot identify every abnormality or confirm a diagnosis by themselves. Dense tissue, movement, technical factors, and harmless changes can make interpretation difficult. A result that needs clarification may lead to extra views, ultrasound, MRI, or a tissue sample. A result described as normal does not replace attention to a new breast change.

A standard mammogram creates two-dimensional X-ray views and may be used alone or with 3D imaging. Ultrasound uses sound waves and can help assess a particular area, especially when a lump is felt. MRI uses a magnetic field and may be considered for specific clinical reasons. The choice depends on your symptoms, examination, breast tissue, and prior results.

The report may describe the breast tissue, any finding seen, and whether further assessment is advised. A request for more imaging does not by itself mean cancer; it means the available pictures do not answer the clinical question fully. Ask the care team which finding prompted the recommendation and what the next appointment involves.

Compression can feel uncomfortable, but it lasts briefly. Tell the technologist if you are pregnant, might be pregnant, have breast implants, or cannot tolerate the positioning. The examination uses X-rays, so the team uses it when the expected information is clinically useful. Follow the facility's instructions about deodorant, clothing, and previous breast images.
