{Abstract}: <B>OBJECTIVE: </B>To explore quantitative differences between genders in morphologic colonic metrics and determine metric reproducibility.<BR><B>METHODS: </B>Quantitative colonic metrics from 20 male and 20 female CTC datasets were evaluated twice by two readers; all exams were performed after incomplete optical colonoscopy. Intra-/inter-reader reliability was measured with intraclass correlation coefficient (ICC) and concordance correlation coefficient (CCC).<BR><B>RESULTS: </B>Women had overall decreased colonic volume, increased tortuosity and compactness and lower sigmoid apex height on CTC compared to men (p<0.0001,all). Quantitative measurements in colonic metrics were highly reproducible (ICC=0.9989 and 0.9970; CCC=0.9945).<BR><B>CONCLUSIONS: </B>Quantitative morphologic differences between genders can be reproducibility measured.
