Diffusion-weighted signal decays of water signals in presence 5 mM Gd-DTPA. The data were obtained at day 11 of the experiment using a diffusion time of 30 ms. The unshifted (intracellular) water resonance (▼) showed nonmonoexponential behavior. The solid line (—) represents a biexponential fit to the data with the following parameters: S(b) = Vf1e−bADC1 + Vf2e−bADC2 with Vf1 = 0.44, ADC1 = 0.71 μm2/ms, Vf2 = 0.56, and ADC2 = 0.11 μm2/ms. The shifted peaks +185 Hz (●) and +130 Hz (○) showed monoexponential behavior with measured ADCs of 3.7 ± 0.8 and 2.9 ± 0.3 μm2/ms, respectively.
