Ultrashort-TE (UTE) imaging of a wet bovine cortical bone sample (A). After air drying for 3 days, signal from bound water remains (B). A bi-component model demonstrates a T2* of 0.30 ms and a fraction of 80.6% for bound water, as well as a T2* of 2.05 ms and a fraction of 19.4% for free water in the wet sample. After 3 days of drying, free water dropped to near zero (C).
