The disclosure relates to a method of measuring tissue hydration or a bodily fluid such a lymph or interstitial fluid. In the method, at least one elastographic parameter of a tissue or bodily fluid may be measured to obtain an elastographic parameter measurement that correlates with a mechanical, pathological, physiological or functional property of the tissue or bodily fluid. The elastographic parameter measurement may be correlated with a tissue hydration value or bodily fluid value, including quantitative tissue hydration or bodily fluid values. Multiple measurements taken over time may be used to detect changes in tissue hydration, amounts of bodily fluid, bodily fluid movement, or rate of clearance of a bodily fluid. The disclosure also relates to a device containing a ultrasound transducer, circuitry able to perform methods of the disclosure, and a display able to display tissue hydration or bodily fluid information.
