Abstract- We analyzed more than 2000 electroimpedance images of the mammary gland in norm and with pathology. The research was carried out utilizing the electrical impedance computer tomograph «MEIK»® (current 0.5 mA, frequency 50 kHz). The following particularities of the electrical impedance image were established. In the norm the electrical impedance image reflected a regular anatomic structure of a mammary gland and the index of the mean electrical conductivity corre-sponded to the age norm. In case of pathology either changes of the anatomic structure of a mammary gland or changes of its mean electrical conductivity index were observed. Thus, estimation of the electroimpedance image should include both a visual analysis of the image as well as quantitative. The vis-ual estimation of the electroimpedance image includes analysis of the following details: the mammary gland contour (presence of deformations, infiltration); the mammary gland anatomy (changes of anatomy, displacement of internal structures, peri-focal infiltration); the lacteal sinus zone (visualization, dilata-tion); local changes of electrical conductivity (presence of hypo- or hyperimpedance areas). The quantitative analysis includes the following particulars: an index of mean electrical conductivity and a histogram of electrical conductivity distri-bution; comparison of histograms with a norm; an index of mean electrical conductivity of the area in question. The article is illustrated with electroimpedance mammograms and tables...
