PURPOSE: The purpose of this work was to analyze the relation between normal colonic wall thickness at @entity694 . METHOD: One hundred consecutively acquired @entity1 were included in our study. All @entity1 were asymptomatic regarding their intestine, and their history was always negative for @entity1944 . All CT examinations were performed for other reasons than @entity1944 . Colonic wall thickness at CT was measured digitally in every @entity1 at four locations and set in relation to the @entity694 . RESULTS: The normal colonic wall thickness ranged from 0 to 2 mm in colonic segments with a diameter of >/=4-6 cm, from 0.2 to 2.5 mm in colonic segments with a diameter of 3-4 cm, from 0.3 to 4 mm in colonic segments with a diameter of 2-3 cm, and from 0.5 to 5 mm in colonic segments with a diameter of 1-2 cm. Maximal colonic wall thickness ranged up to 6 and 8 mm in the proximal and distal colon, respectively, if the measured colonic segment showed a luminal width of <1 cm according to contraction. DISCUSSION: The normal colonic wall thickness at CT should be regarded as a dynamic value that stays in clear relation to the @entity694 . In contracted colonic segments, a colonic wall thickness of 6-8 mm may still be normal. On the other hand, a colonic wall measuring 5 and 3 mm should be regarded as thickened if found in colonic segments with a luminal width of >2 and 4 cm, respectively.
