Mammogram (sometimes called Digital Mammogram or 2D Mammogram)
A screening mammogram is an X-ray picture of each breast taken from two angles. It is typically done to check for breast cancer in women who have no signs or symptoms of cancer.
A 3D mammogram complements a standard mammogram and is done at the same time. During the 3D part of the exam, the X-ray arm sweeps in a slight arc over your breast taking multiple breast images. A computer then produces a 3D image of your breast tissue in one millimeter slices, which allows the radiologist (the doctor reading your images) to see the breast in more detail. 3D mammograms are particularly useful to screen women that have dense breast tissue.
