What mammography is
Mammography is an imaging exam that uses low-dose X-rays to produce detailed images of the breasts. It is often requested for screening or to assess breast changes identified by the doctor or by the person themselves.
CRMA performs mammography in two modes: 2D mammography (conventional) and 3D tomosynthesis (a technique that acquires multiple images at different angles and reconstructs them into thin slices). The choice between 2D, 3D or both is made by the referring doctor. Both are performed in direct digital mammography, on the Fujifilm Amulet Sophinity system (with tomosynthesis).
In some cases, mammography is complemented with a breast ultrasound on the same day.
How it is performed
The exam generally takes 10 to 20 minutes. Standing at the mammography unit, the radiographer positions one breast at a time on a platform. A transparent plate compresses the breast for a few seconds while the image is acquired. Compression is needed to spread the breast tissue and obtain clear images with the lowest possible dose.
Preparation
- Fasting: not needed.
- Clothing: we recommend two-piece clothing, so you only need to undress from the waist up.
- Deodorant, talcum powder, perfume, cream: do not use on the underarms or breasts on the day of the exam — some formulations contain metallic particles that can appear as artefacts.
- Necklaces and piercings: remove them before the exam.
- Breast implants: let us know when you book.
- Menstrual period: if your breasts become tender before your period, the best time for the exam is between the 7th and 12th day after your period starts.
- Previous exams: always bring your previous mammograms on CD or on paper.
Results
The report is written by a radiologist. Reading follows the international BI-RADS classification, which indicates the type of follow-up suggested. You receive the printed report and the images on CD in DICOM format.
