Incorrect
assessment of clinical volume status leads to increased mortality and
healthcare costs yet there are no accurate, non-invasive, and quantitative
methods to assess this health metric. We evaluated the ability of a portable NMR sensor and relaxometry techniques to detect fluid
changes in hemodialysis (HD) patients during the course of HD
treatment. There was a significant difference between relaxation values of HD patients compared to healthy subjects.
