^aTransverse diameter from 2.6 to 3.0 cm

^bTransverse diameter more than 3.0 cm

^cLymph nodes (pre-sacral in all cases) were considered enlarged with the largest diameter greater than 5 mm

^dKidney, liver, uterus and ovary lesions that showed net hyperintensity on T2-weighted and net hypointensity on T1-weighted images, with well-defined margins were considered presumably benign without the need of further work-up

^eSolid benign lesions were classifid as E2 if homogeneously hypointense on T1- and T2-weighted images, suggesting fibromiomas

^fAnatomical abnormalities were: retroverse uterus, uterus didelphis, bicornuate uterus, septated uterus

^gColorectal wall thickening was not defined because colorectal enema was not performed; any wall thickening considered suspicious by consensus of the two observers was included in the study
