Fig. 3 Line plot shows relationship of highest relative cerebral
blood volume (rCBV) values (expressed as a ratio of highest rCBV value of
tumor relative to highest rCBV value of normal contralateral lentiform
nucleus) along x-axis and highest relative permeability values
(contrast enhancement signal intensity expressed as number of SDs above mean
value in normal unenhancing tissue in contralateral hemisphere) along
y-axis. Kendall's tau correlation was 0.7778 (p = 0.0035),
indicating strong correlation between highest relative permeability values on
dynamic contrast-enhanced imaging and highest rCBV values on dynamic
susceptibility contrast imaging.
