Contrast-enhanced digital mammography is an advanced modality of breast imaging, which helps in improvement of the breast cancer screening process. Contrast-enhanced digital mammography generates a contrast-enhanced, full-field, and high-resolution image of digital mammography, similar to MRI, to provide lesion vascularity details inside the breasts. The technology combines the standard, full-field digital mammography (FFDM) with a low-osmolarity, intravenous, iodinated contrast medium. Detecting malignancies in extremely dense and heterogeneous breasts with the help of MRI is difficult.

Contrast-enhanced digital mammography highlights the malignant area with the help of a contrast agent, facilitating the tumor detection. In contrast-enhanced digital mammography, an iodine-based contrast medium is administered intravenously in the arm vein before capturing the mammographic image and two subsequent images at low energy and high energy are obtained. The low-energy image reveals calcification and soft tissue details.
The two images are then subtracted to generate a single, contrast-enhanced digital image, which highlights the neovascularity inside the breasts. Owing to the fact that cancerous tissues take up more iodine than normal tissues, the resulting contrast-enhanced image maximizes the conspicuity of the contrast agent in the breasts. This reveals the lesions with higher neovascularity and approximately ten times the resolution of the normal breast MRI.

The superiority of contrast-enhanced digital mammography over the breast MRI and standard mammography in detecting breast tumors, rising prevalence of the breast cancer across the globe, and cost-effectiveness of the contrast-enhanced digital mammography modality are major factors estimated to fuel The Contrast-Enhanced Digital Mammography Market during the forecast period. However, lack of awareness about the contrast-enhanced digital mammography technology among the people in developing countries is anticipated to restrain the market during the forecast period.
