Representative DSC data. (a) An axial T1 post-Gd image shows enhancing tumor. The grids indicate the spatial location of ΔR* curves in B. (b) In the corresponding ΔR* curves, peak height (PH) values in the tumor (dark grey) were normalized by the average PH from normal brain tissue (light grey voxels). The right panel in B shows an example of ΔR* signal evolution over the entire acquisition period (75 s).
