A digital 3D screening mammogram is a routine low dose x-ray of each breast performed to detect small abnormalities before they can be felt on an exam. The purpose of the screening mammogram is to distinguish normal structures that are components of the breast tissue from abnormal lesions.
A diagnostic mammogram uses special low dose x-ray views to evaluate a breast concern or to “get a closer look” at a finding on a recent screening mammogram. The special views may use 3D mammography, magnification, or spot compression to further characterize an area of interest.
