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.

By comparison, an image showing the nipple in profile allows for better detection of subareolar masses and helps prevent the nipple from being mistaken for a mass (Figure 2B).Therefore, misregistration artifact, similar to that seen in MRI with patient motion, may be present when pectoral outlining is seen.Vessels enhance more prominently and wash out on the first view than on subsequent views, similar to results of MRI (Figure 4).When limitations prevent the nipple from being placed into profile, a BB marker should be used to denote its location.The majority of pectoralis muscles do not show enhancement on subtracted images.However, a small percentage (11%) of subtracted images demonstrate pectoral outlining, which mimics faint enhancement (Figure 3).Pectoral outlining is an artifact attributed to patient motion and does not indicate inflammation or pathologic change within the muscle itself.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.A less common appearance is minimal enhancement at the base of the nipple.In patients with flat nipples, a prominent thin rim of enhancement may be seen contiguous with the adjacent skin.
