The pharmacokinetic parameters in each grade of glioma^{^a}

	Grade II^{^b}/Low-Grade^{^c}	Grade III^{^b}	Grade IV^{^b}	High-Grade^{^c}
K^trans ^{^d}	0.027 ± 0.041	0.057 ± 0.091	0.158 ± 0.226	0.122 ± 0.195
Ve^{^e}	5.809 ± 10.381	15.469 ± 26.165	45.103 ± 63.888	35.059 ± 55.920
Vp^{^e}	3.858 ± 3.958	5.735 ± 5.772	10.624 ± 12.396	8.826 ± 10.723

↵a All data are means.
↵b There were statistically significant differences among grades (P < .01).
↵c There were statistically significant differences between low- and high-grade (P < .01).
↵d Data for K^trans are in units of minute⁻¹.
↵e Data for Ve and Vp are percentages.
