Mammogram and Digital Tomosynthesis (3D Mammogram) are essentially X-ray and CT of the breasts. Both use low energy X-rays to examine the breast tissues and to detect calcifications and various lesions. Mammogram’s usually produces two X-ray images of each breast but more images may be obtained on a case-by-case basis. On the other hand Digital Tomosynthesis generates a three-dimensional image of the breast and allows better visualization and assessment of dense breast tissue.


Do not wear any powders, creams or deodorants on the area. If you have Breast implants, please inform the reception staff.
