Comparison of Contrast Enhanced Mammography and Contrast-Enhanced Breast MR Imaging

Contrast-enhanced mammography (CEM) is a contrast-enhanced modality for breast cancer detection that utilizes iodinated contrast and dual-energy imaging performed on a digital mammography unit with only slight modifications. It is approved by the US Food and Drug Administration, commercially available, and in routine clinical use at centers around the world. It has similar sensitivity and specificity to MR imaging and has advantages in terms of cost, patient acceptability, and examination time. MR imaging has some advantages compared with CEM, especially in its ability to image the complete axilla and the chest wall.
