Study of Correlation between MRI Morphology of Primary Tumor and Extramural Vascular Invasion in Rectal Cancer

Table 3

Diagnostic predictive values of NP for prediction of EMVI from ROC.

Diagnostic values	AUC	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)	Accuracy (%)
NP	0.82	73.58	90.29	79.59	86.92	84.62

NP: nodular projection at the primary tumor’s edge; AUC: area under the receiver operating characteristics curve; PPV: positive predictive value; NPV: negative predictive value.
