Mammography is a screening method for detecting breast cancer. With the development of medical science and modern technology, a new digital method called contrast mammography is being introduced into the healthcare system. It is based on breast tissue imaging using a contrast agent and dual - energy technique. Recombination of high and low energy images produce dual images: one low energy image corresponding to classical mammographic examination, and the other, a recombined image with a prominent contrast - stained lesion. Contrast mammography enables more precise highlighting of new, benign or malignant formations. Due to the high sensitivity of this method, it is often used as a replacement or supplement to MR diagnostics and 3D mammography. Since it is just being introduced in healthcare facilities, there is a possibility testing the quality of this method more prominently.
