Zusammenfassung:	Methods for measuring cross-sectional areas in luminal organs. In at least one embodiment of a method for measuring a size parameter of a targeted treatment site of the present disclosure, the method comprises the steps of introducing an impedance device into a treatment site, the impedance device selected from the group consisting of an impedance catheter and an impedance wire; injecting a first solution of a first compound having a first conductivity into the treatment site; measuring a first conductance value at the treatment site using the impedance device, the first conductance value indicative of a bolus of the first solution, and calculating a size parameter of the treatment site based in part upon the first conductivity of the first solution, the first conductance
