Table 2:

Correlations between rCBV and fractional MVA under different PLD and modeling conditions^{^a}

Conditions for rCBV Measurement	Pearson Correlation (r)	P Value	Spearman Correlation (ρ)	P Value
Fractional MVA	1.00	–	1.00	–
No PLD (IBN)	0.46	.02	0.33	.12
No PLD (NICE + gvf)	0.51	.01	0.26	.19
No PLD (NICE − gvf)	0.35	.10	0.18	.39
PLD (IBN)	0.64	<.001	0.58	.001
PLD (NICE + gvf)	0.53	<.01	0.28	.15
PLD (NICE − gvf)	0.59	.001	0.40	.04

Note:—+ indicates with; −, without; –, not applicable; gvf, γ variate fitting.
↵a Both PLD correction and IBN software modeling were needed to achieve maximal correlation.
