Table 5 Preoperative evaluation of volume transfer constant, rate constant, and extravascular extracellular volume fraction for T stage of colorectal cancer

Parameter	Cutoff value	AUC	SE	Sig	95%CI	Youden index	Specificity (%)	Sensitivity (%)
Ktrans (minute^-1)	0.935 minute^-1	0.930	0.036	0.000	0.859-1.000	0.762	81.48	94.70
Kep (minute^-1)	2.135 minute^-1	0.828	0.062	0.000	0.707-0.950	0.546	70.37	84.20
Ve (%)	0.580%	0.872	0.051	0.000	0.772-0.973	0.620	77.78	84.20

AUC: Area under the curve; SE: Standard error; Sig: Significance; CI: Confidence interval; Ktrans: Volume transfer constant; Kep: Rate constant; Ve: Extravascular extracellular volume fraction.
