摘　　要：乳腺癌的早期检测与诊断是目前国际研究的难点与热点。癌组织与正常组织与良性肿瘤组织之间的电特性的差异为乳腺癌的早期检测提供了有效的辅助诊断信息。本文在此前提下介绍了一种高分辨率的医学电阻抗成像技术-磁共振电阻抗成像技术的成像原理与成像算法,然后介绍了MREIT技术在早期乳腺癌检测方向的应用,最后分析了该研究方向的发展前景以及目前存在的问题。Breast cancer detection and diagnosis is a study. It has been shown that electrical properties those of normal and benign tissues. In this paper, a difficult point and hot issue of present international of malignant tissues are significantly different from new medical impedance imaging modality （Magnetic resonance electrical impedance tomography-MREIT） is first introduced, including its mathematical theories and the reconstruction algorithms. Then its application in early breast cancer detection research is introduced in detail. Finally, its future research direction and major problems are summarized.
