Contrast-Enhanced Mammography (CEM)

Contrast-enhanced mammography (CEM) is a diagnostic exam our radiologist may recommend after an inconclusive mammogram or an abnormal ultrasound — particularly if you are at high risk for breast cancer or have dense breast tissue.

How CEM works

CEM combines mammography with an injection of iodinated contrast, similar to a CT exam. The study captures four mammography views — two low-energy and two contrast-enhanced recombined views in the same positions — then subtracts the baseline images. What remains shows precisely where contrast has pooled, highlighting areas of unusual blood flow that may indicate cancer.

Why patients appreciate CEM

• The exam itself takes less than seven minutes
• Subtracted imaging reduces false-positive results
• The GE Senographe Pristina system offers greater comfort and reduced noise
• Radiation dose is personalized and optimized for your breast density

Your radiologist will discuss whether CEM is the right diagnostic step for your situation — often it provides answers without the longer path of MRI.
