Correlation of rCBV and rCTH.
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
Scatterplots showing the very weak correlation of rCBV and rCTH in (A) the enhancing tumor (R2 = 0.01; p = 0.41) and (B) the peri-focal edema (R2 = 0.06; p = 0.05), suggesting that they provide different information. Mean values for each patient are plotted. High-grade gliomas are marked with blue, low-grade gliomas with red.
