  1. Data in parentheses are 95% confidence interval range
  2. ET extended Tofts, DP distributed parameter, Ktrans transfer constant, Kep efflux rate constant, Vp blood volume, F blood flow, PS permeability surface area product, MVD microvessel density. Ktrans and Kep are in units of min−1, Vp is in units of mL/100 mL, F and PS are in units of mL/min/100 mL, MVD are in units of microvessels per mm2. AUC = area under the receiver operating characteristic curve
