PurposeTo perform a radiologic-pathologic correlation analysis of sigmoid colon in patients undergoing pre-operative CT Colonography (CTC) after an episode of acute diverticulitis (AD).Methods
Fifty-nine consecutive patients (31/28 M/F; 58 ± 13 years) underwent CTC 55 ± 18 days after AD, 8 ± 4 weeks before surgery. Thirty-seven patients (63%) under...

Background
Following an episode of acute diverticulitis, surgical guidelines commonly advise routine colonic follow-up to rule out underlying malignancy. However, as a CT of the abdomen is frequently performed during clinical work-up, the routine need for colonic follow-up has become debated.
Purpose
To evaluate the need for routine CT colonograph...

Different scenarios embrace radiological imaging and colonic diverticula, including asymptomatic (diverticulosis) and symptomatic patients (acute diverticulitis, follow-up of acute diverticulitis, chronic diverticulitis). The role of imaging is in evolution; the role of computed tomography (CT) is validated and is widely supported by evidence in the case of acute diverticulitis, but this is not the case for acute diverticulitis follow-up or with symptoms related to diverticula without acute inflammation. In these settings, computed tomography colonography (CTC) is gaining consensus as the preferred radiological test.KeywordsCT ColonographyColonoscopyAbdominal CTDiverticular diseaseAcute Diverticulitis
