Selected parameters from fitting Dataset B using 7-parameter monoexponential model (Supplementary Information) using three different processing approaches. U: Unconstrained analysis. C-$\alpha \beta$: Constrained analysis using $\alpha \beta$ Kalata filter. C-$\alpha$: Constrained analysis using $\alpha$ Kalata filter. Although performance of the model fit is similar across much of the imaged area, the unconstrained analysis assigns inaccurate values of switching times to a large region on the interior of the tumor (white arrows).
