Cover Story: Micro-computed tomography (micro-CT) is an imaging technique that provides highly detailed 3D visualizations of target specimens. In breast cancer research, micro-CT has emerged as a promising tool for analyzing microcalcifications (MCs)—tiny calcium deposits which may serve as early indicators of malignancy. The applications of micro-CT in this field are diverse, spanning ex vivo studies, animal models, and phantoms. Its use includes imagining feasibility and optimization for breast MC detection/diagnosis, comparisons and synergies with other modalities, scanner and algorithm development, and the enhancement of MC detection using contrast agents. This scoping review explores the current state of micro-CT in breast MC analysis, highlighting its potential to deepen our understanding of MC characteristics. View this paper
