Ischemic Colitis: CT Evaluation of 54 Cases
Abstract
PURPOSE: To review the computed tomographic (CT) scans and medical records of 54 patients with proved ischemic colitis, define the spectrum of CT findings, and assess the effect of CT imaging on treatment. MATERIALS AND METHODS: The mean age of the patients was 72 years. CT scans were analyzed for the presence of colonic abnormalities and associated findings. Ischemia was clinically unsuspected in 16 patients (30%). RESULTS: Segmental involvement was seen in 48 patients (89%), with a mean length of involvement of 19 cm (range, 5-38 cm). Wall thickness varied between 2 and 20 mm (mean, 8 mm). All parts of the colon were involved. The CT appearance of the colonic wall varied: (a) A wet appearance with heterogeneous areas of edema was seen in 33 patients (61%). (b) A dry appearance with mild homogeneous thickening was seen in 18 patients (33%). (c) Intramural air was present in three patients (6%). Ischemia resolved in 41 patients (76%), and complications occurred in 13 patients (24%). CONCLUSION: CT can be used to confirm the clinical suspicion of ischemic colitis, to suggest ischemia when it is unsuspected, and to diagnose complications. Intrinsic colonic abnormalities cannot be used to diagnose or predict the development of infarction.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
