Table 1.

AUC and the Washout Log Slope can Differentiate Glioblastoma and Melanoma Metastases from Hypovascular Metastases, but not from Each Other

	AUC	Washout Log Slope	K_trans	V_p
GBM versus Melanoma	.790	.772	.386	.614
GBM versus Hypovascular Mets	.047^*	.019^*	.493	.493
Melanoma versus Hypovascular Mets	.046^*	.024^*	.865	.955

Hypervascular tumors showed increased AUC and washout log slope in the signal intensity time curve as compared to hypovascular tumors. Pharmacokinetic variables (K_trans and V_p) did not differ between the two pathologies. Glioblastoma and melanoma did not differ from each other in all four parameters.

Significant results (P < .05).
