    Abstract: In accordance with one aspect of the present technique, a method is disclosed. The method includes applying a mechanical perturbation to a tissue region using a displacement device. The method further includes calculating a compression impedance of the tissue region in response to applying the mechanical perturbation. The method further includes retracting the displacement device and calculating a retraction impedance of the tissue region in response to retracting the displacement device. The method also includes determining a hydration level of the tissue region based on at least one of the compression impedance and the retraction impedances.

    Abstract: One system includes a pattern generator that generates one or more excitation patterns suitable for probing a hydration level of a tissue of a subject at one or more depths from a surface of the subject into an interrogation region. Each of the excitation patterns has a spatial sensitivity at one of the one or more predetermined depths. A data analysis module receives one or more measured responses of the subject at a plurality of electrodes to excitation applied by the plurality of electrodes based on the one or more excitation patterns and determines one or more hydration changes at the one or more depths within the subject based on the measured responses. Each of the measured responses corresponds to the one of the one or more predetermined depths for which the applied excitation pattern has spatial sensitivity.

    Abstract: Methods for measuring liver fat mass are provided. One method includes acquiring dual-energy two-dimensional (2D) scan information from a dual-energy X-ray scan of a body and generating a dual-energy X-ray image of the body using the 2D scan information. The method further includes identifying a region of interest using the dual-energy X-ray image and determining a subcutaneous fat mass for each of a plurality of sections of the region of interest. The method also includes determining a liver fat mass for the region of interest based on the determined subcutaneous fat mass for each of the plurality of sections.
