They found that CEDM had a sensitivity of 93% vs a sensitivity of 90% for FFDM with ultrasonography, as well as improved specificity (63% for CEDM vs 47% for FFDM with ultrasonography). Predominately, the skin is nonenhancing or shows a thin line of enhancement.In a comparison of CEDM with MRI, 2 studies have shown that CEDM is similar to MRI. Rarely, it shows artifactual thickening not seen on the standard 2-dimensional image.

A contrast agent is given to patients to enhance the ability to see blood vessels and organs on medical images.

These images provide greater detail when necessary to help healthcare professionals diagnose potential problems.

Contrast-enhanced digital mammography (CEDM) takes sequential images at high and low energies that are used to construct a digitally subtracted image, highlighting areas of contrast medium enhancement.

The low-energy image is of the same diagnostic quality as standard 2-dimensional mammography.

The differences in nipple enhancement between MRI and CEDM are likely secondary to a combination of the differing contrast agents used and the compression applied with CEDM.

As with typical FFDM, every effort should be made to place the nipple in profile.

A contrast mammography examination, commonly referred to as contrast enhanced 2D imaging (CE2D), is advanced imaging that provides additional information beyond a normal mammogram that may improve breast cancer detection.

Contrast mammography refers to the imaging of a drug, known as a contrast agent, using mammographic X-ray imaging equipment.

In addition, the authors outline a standardized reporting system to help further streamline interpretation and reporting of CEDM images.

CEDM is a quick, well-tolerated, relatively low-cost breast imaging technique that combines standard full-field digital mammography (FFDM) with an intravenous, low-osmolar, iodinated contrast medium.
