The rectal MRI consisted of T \u00a02WI in three planes and axial DWI (b-values, 0, 1000\u2009s mm\u20132). Two radiologists blinded to the pathologic results independently reviewed the T \u00a02WI first, and then the combined T \u00a02WI and DWI 4 weeks later. They recorded their confidence scores for EMVI on a 5-point scale (0: definitely negative and 4: definitely positive). The diagnostic performance of each reading session for each reader was compared by pairwise comparison of receiver operating characteristic curves. The area under the ROC curve (AUC) was considered as the diagnostic performance. The result of a histopathological examination served as the reference standard for EMVI.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n
