Case summary a 54-year-old caucasian woman presented with a painful left breast lump the patient's medical history was significant and included a pituitary adenoma, a hysterectomy, and a unilateral oophorectomy at age 53 the patient's menopausal status was unknown but she had no history of. Contrast-enhanced dual-energy mammography (cedm) is a promising new breast imaging tool for breast cancer detection in cedm, an iodine-based contrast agent is intravenously administered and subsequently, dual-energy mammography is performed this results in a set of images containing both a regular. With contrast-enhanced digital mammography (cedm), which uses iodinated contrast agents to increase attenuation in areas exhibiting tumour angiogenesis and image subtraction to cancel normal tissue signal two techniques have shown favourable results in clinical pilot studies single-energy (se) and dual- energy.

New technologies in mammography, such as 3-dimensional (3d) tomosynthesis and contrast-enhanced spectral mammography (cesm), have a role in increasing (2d) mammograms by utilizing a dual-energy acquisition system, which then generates a subtracted image to outline areas of enhancement.

Enhancement to depict cancers that would otherwise be occult on standard unenhanced mammography those efforts resulted in the development and clinical testing of contrast-enhanced digital mammography (cem) using the dual energy subtraction technique (7) today cedm is available commercially for clinical use. Another method to visualize the contrast agent, so-called dual-energy contrast- enhanced digital mammography, relies on the energy dependence of x-ray attenuation in the contrast agent, and in one in this study, we used single-shot photon-counting tomosynthesis, which splits the x-ray spectrum directly in the detector.
