Table II.

Pearsons correlation between the K^trans, k_ep and v_e values of tumor entity and peritumor edema and the histopathological tumor grade.

	Ktrans, min−1		kep, min−1		ve
Grade	r	P-value	r	P-value	r	P-value
Tumor entity	0.951	<0.001a	0.804	<0.001a	0.766	<0.001a
Peritumor edema	0.438	<0.001a	0.385	<0.001a	0.397	<0.001a

K^trans, forward volume transfer constant; k_ep, backflux rate; v_e, fractional volume.
