Prognostic Value of Electrical Impedance Spectroscopy (EIS) When Used as an Adjunct to Colposcopy - A Longitudinal Study.

EIS does offer prognostic information on the risk of CIN2+ developing over the three-year period following the EIS measurements. The changes in EIS spectra are consistent with an increase in cell size diversity as pre-malignancy develops. These changes may be a consequence of increased genetic diversity as neoplasia develops.
