TABLE 2.
Summary of tDKI data measured in GL261 and 4T1 tumors using a linear fit to D(t) and the Kärger model to K(t) for t = 200–800 ms. A linear model of D(t) is defined as D(t) = At+D0 with diffusion time t in milliseconds for consistency with the unit of D. The reported values are medians with interquartile ranges in parentheses
