Assessment of tissue perfusion of pancreatic cancer as potential imaging biomarker by means of Intravoxel incoherent motion MRI and CT perfusion: correlation with histological microvessel density as ground truth

Table 3 Spearman rank correlation coefficients

Spearman correlations between mean f_tumor from DWI IVIM and mean CT perfusion parameters (n = 19)
	BF_tumor	BV_tumor
f_tumor	0.668 *	0.672 *
Spearman correlations between histological microvessel parameters, mean f_tumor from DWI IVIM and mean CT perfusion parameters (n = 10)
	f_tumor	BF_tumor	BV_tumor
MVD_tumor	0.770 *	0.697 *	0.661 *
MVA_tumor	0.818 *	0.709 *	0.661 *

Correlation coefficients that are significantly different from zero (p < 0.05) are marked with *. Abbreviations: BF: blood flow, BV: blood volume, f: perfusion fraction, MVA: microvessel area, MVD: microvessel density
