A New Method to Improve the Accuracy in EIS Diagnosis

Abstract

Electrical impedance scanning (EIS) has been demonstrated a valuable noninvasive adjunctive technology for breast cancer diagnosis. Although EIS is a successful impedance-imaging technology for breast cancer diagnosis, the clinical studies showed a high false-positive rate limited its application. The reasons are mainly concluded as following: (1) EIS result depends critically on the experience of the operator. (2) For a typical hyperplasia, EIS result in some cases shows a high positive finding ratio. So for EIS examination, how to decrease the dependence on the operator and how to decrease the false positive ratio induced by a hyperplasia are all important. Now, our group is trying to improve the accuracy of EIS diagnosis for breast diseases. In our study, three main improving technologies were used, which were real-time imaging technology, multi-frequency parameter analysis technology and imaging characteristic recognition algorithm.
