Table 3. Correlation of DCE-MRI Parameters with Histologic Parameters of Two Contrast Agent Groups in 24-Hour Follow-Up Studies.

DCE-MRI Parameters	NF (n = 13)		MVD (n = 13)
	1.857 ± 0.69 (P792, n = 7)		30.8 ± 8.6 (P792, n = 7)
	2.0 ± 0.632 (Gd-DOTA, n = 6)		34.2 ± 11.7 (Gd-DOTA, n = 6)
	Correlation Coefficient	P*	Correlation Coefficient	P*
Ktrans (min-1)	-0.21	0.351	0.26	0.287
iAUC (mmol/sec)	-0.25	0.282	0.21	0.41

^*Spearman's correlation. DCE-MRI = dynamic contrast-enhanced magnetic resonance imaging, iAUC = initial area under gadolinium concentration-time curve until 60 seconds, MVD = microvessel density, NF = necrotic fraction
