Contrast-enhanced mammography (CEM) is an imaging technique that uses iodinated contrast medium to improve visualization of breast lesions and assessment of tumor neovascularity. Through modifications in x-ray energy, high- and low-energy images of the breast are combined to highlight areas of contrast medium pooling. The use of contrast material introduces different workflows, artifacts, and risks related to the contrast medium dose. In addition, the need to acquire multiple images in each view introduces different workflows, artifacts, and risks associated with the radiation dose. Although CEM and conventional mammography share many underlying principles, it is important to understand how these two mammographic examinations differ and the mechanisms that facilitate image contrast at CEM.

对比增强乳腺摄影（CEM）是一种影像学技术，它使用碘造影剂来提高对乳腺病变的可视化程度和对肿瘤新生血管的评估。通过对 X 射线能量的调整，可以将乳腺的高低能图像进行组合，以突出对比剂蓄积的区域。造影剂的使用引入了不同的工作流程、伪影和与造影剂剂量相关的风险。此外，在每个视图中采集多个图像的需求引入了与辐射剂量相关的不同工作流程、伪影和风险。尽管 CEM 和常规乳腺摄影有许多共同的基本原理，但了解这两种乳腺摄影检查的区别以及在 CEM 中促进图像对比的机制非常重要。RSNA，2021 年。
