n = 40. Bold red values indicate significant correlations without Bonferroni correction (P < 0.05).
PET = positron emission tomography; CT = computer tomography; DCE-MRI = dynamic contrast enhanced magnetic resonance imaging; AUC = area under the curve; Ktrans = wash-in constant from plasma to tissue constant; Ve = fraction of extravascular extracellular space; Kep = wash-out constant from tissue to plasma; Vp = fraction of vascular space; SUV = standardized uptake value; TBR = target-to-background ratio.
