Comparison of cerebral blood volume and vascular permeability from dynamic susceptibility contrast-enhanced perfusion MR imaging with glioma grade.

Abstract

rCBV with strongly correlated with tumor grade; the correlation between K(trans) and tumor grade was weaker. rCBV and K(trans) were positively but weakly correlated, suggesting that these parameters demonstrate different tumor characteristics. rCBV is a more significant predictor of high-grade glioma than K(trans).
