Minimally-invasive electrical impedance spectroscopy in lung tissue: present and future trends

Abstract Electrical impedance measurements performed in-vivo and in-situ in lung tissue so far have focused on detecting different pathologies, including neoplasm. Once its ability for this has been established, the authors intend to investigate whether it is possible to detect peripheral lung nodules. The preliminary measurements collected show differences in the measured spectra and model parameters between the different types of lesions collected (solid nodules, partially solid nodules and ground-glass nodules).
