Figure 1

The signal intensity histograms (bin size = 10) of choroid plexus (n = 74) and SBS (n = 219) measured on susceptibility weighted images (SWI) in 46 GBM patients are shown in (a) and (b), respectively. The corresponding susceptibility differences of choroid plexus and SBS regions with respect to NAWM are shown in the histograms in (c) and (d), respectively, with a bin size of 0.03 ppm. (The white and grey bars indicate regions of the choroid plexus and SBS, respectively.)
