{Abstract}: OBJECTIVE: To explore quantitative differences between genders in morphologic colonic metrics and determine metric reproducibility.
METHODS: 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).
RESULTS: 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).
CONCLUSIONS: Quantitative morphologic differences between genders can be reproducibility measured.
