Abstract

Breast cancer is the most common cancer worldwide among women, and is the second cause of death due to cancer among women. Breast density is one of the strongest risk factors to develop breast cancer, it may increase the likelihood of having breast malignancy up to six folds. Mammography plays a pivotal role in cancer detection and follow-up, one of the most important limitations of mammography is that its diagnostic performance depends heavily on breast density. To overcome this limitation, new techniques developed, Dual-energy contrast-enhanced mammography is one of the latest developments and seems to be the most promising approach for routine clinical use. It is feasible, easily accomplished and interpreted and well tolerated.
It is superior to conventional mammography as it provides functional assessment of tumor angiogenesis which is additional to morphological findings. To date DE CEDM has been valuable in increasing the cancer detection rate in dense breasts, improving staging and improving the selection of patients for biopsy. In addition, its diagnostic performance might match that of the most accurate breast imaging modality available to date: breast MRI. So that it is particularly helpful for the assessment of lesion size, multifocality of breast cancer and patient follow up for tumor recurrence after surgery or neoadjuvant chemotherapy.
One of the major clinical applications for dual-energy CEDM is its use as a “problem-solving” tool in cases of equivocal mammographic and ultrasound assessments, and so it may be considered as a screening modality in high-risk young women.
In conclusion, Dual-energy contrast enhanced digital mammography is a potentially important imaging tool in detecting and diagnosing breast cancer especially in dense breasts. It might be an alternative imaging method for MRI, especially when MRI availability is limited or contraindicated.
