Fig. 1.
An illustration of the TDR contrast, as proposed in the original study (Dell’Acqua et al., 2019). Both signals (left) are simulated at a b value of 8 ms/μm2, with Δ = 21 ms, δ = 9 ms, G = 276.8 mT/m for S1 and Δ = 55 ms, δ = 9 ms, G = 162.9 mT/m for S2, respectively. The relative difference between the two signals produces the TDR contrast on the right, that is monotonically increasing with pore size for the range considered here.
