Table 4 Spearman correlation analysis of volume transfer constant, rate constant, and extravascular extracellular volume fraction with T and N stages of colorectal cancer

Parameter	T stage		N stage
Parameter	r	P value	r	P value
Ktrans (minute^-1)	0.528	0.002	0.519	0.002
Kep (minute^-1)	0.503	0.004	0.602	0.001
Ve (%)	0.496	0.005	0.520	0.002

Ktrans: Volume transfer constant; Kep: Rate constant; Ve: Extravascular extracellular volume fraction.
