VERDICT dMRI showed a good overall repeatability of the mean estimated parameter values within the studied tumours. However, some local clusters of voxels showed larger differences between repeated scans.
Figure 2. Colormaps of cell radius index (R), intracellular volume fraction (fIC), vascular volume fraction (fVASC), and extracellular extravascular volume fraction (fEES) as estimated by VERDICT in the central slice of an example tumour. Colormaps are shown for two repeated measurements (M1 and M2) and the difference between the repeated measurements (Δ)
