title: CT colonography features of sigmoid diverticular disease.
abstract: OBJECTIVE
  The objective of this study is to assess the sigmoid distensibility during CT colonography (CTC) in patients with diverticular disease.
  
  
  METHODS
  Consecutive patients without a history of pelvic radiation or neoplasms underwent 150 CTC. Three radiologists in consensus evaluated axial images for colonic distention, luminal diameters (mm), diverticula, and muscular thickening.
  
  
  RESULTS
  The minimum colon diameter in patients with muscular thickening was significantly smaller, irrespective of the presence of diverticula (P=.009).
  
  
  CONCLUSIONS
  Muscular thickening with diverticular disease was associated with significantly less sigmoid colon distension.
