Tomosynthesis refers to which imaging modality?

• A. 3-D mammography
• B. Traditional 2-D film mammography
• C. Ultrasound tomography
• D. Magnetic resonance thermography

Answer: (A)

Tomosynthesis is a 3-D mammography technique. It uses multiple low-dose X-ray projections taken from different angles around the breast and reconstructs these into a stack of thin slices. This 3-D view helps separate overlapping tissues, making it easier to detect small cancers that can be hidden in a single 2-D image, and is especially helpful in dense breasts. It is distinct from traditional 2-D film mammography, ultrasound-based imaging methods, or MR-based thermography, which are different modalities with other principles and purposes.
