Table 1.
Measured T1, T2, correlation times (τc), and relative populations of water reservoirs obtained from the untreated or treated (collagenase or EDTA) intact bone. The numbers shown after the ± symbol for any of the T1 and T2 relaxation times represent the half-width of the peak observed in the 2D ILT maps and have been propagated to the correlation times.
