Contrast-enhanced spectral mammography (CEM) is a specific type of mammogram exam that uses medical imaging contrast to create a special picture of the breast tissue.
Essentially, the image that CEM creates is a composite of two images taken simultaneously.
A technician will start an IV and begin administering the contrast intravenously. It takes two minutes for the contrast to spread throughout the body following which, the technologist will take images of both of the breasts.
Contrast-enhanced spectral mammography (CEM) only takes a little longer than a standard mammogram.
