Bioelectrical Impedance Spectroscopy (BIS)

Measure Definition:

Bioelectrical impedence spectroscpy is a noninvasive and comparatively inexpensive type of bioelectrical impedance analysis (BIA) to assess body composition that  can be utilized in studies of any size or duration (1).  The multisegmental, multifrequency BIS device allows for the identification of more components of bioimpedance (capacitance, resistance, etc.) than single-frequency BIA devices.


Diagnostic Imaging

Construct Definition (and Source):

Any method that uses a visual display of structural or functional patterns of organs or tissues for diagnostic evaluation. (NCI
