Abstract

Acute mesenteric ischemia (AMI) is a life-threatening condition that often presents with abdominal pain. Early diagnosis with contrast-enhanced computed tomography and revascularization can reduce the overall mortality in AMI. This article reviews practical etiological classification, pathophysiology of imaging manifestations and common pitfalls in intestinal ischemia.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Dual-energy CT enhances intraluminal contrast, which can be useful when contrast timing or injection are issues.

    “Dual-energy CT is an emerging tool that enhances intraluminal contrast, which can be particularly useful in cases where contrast timing or injection are issues [26,27].”

    From Revascularization Strategies for Acute and Chronic Mesenteric Ischemia: A Narrative Review (2024) · cites this paper as [26]

    The Future directions section (page not provided) says dual-energy CT is becoming more commonplace and can make differences in bowel-wall enhancement more conspicuous. It does not say that it enhances intraluminal contrast or is particularly useful when contrast timing or injection are problematic. The CT protocol section discusses bolus tracking, but does not connect it to that claimed benefit of dual-energy CT. (LLM, conf=0.86)

  • Doppler ultrasound has limited utility in diagnosing acute mesenteric ischemia due to gas within the bowel lumen and potential limitations in visualizing mesenteric vessels in larger patients.

    “Doppler ultrasound has limited utility in diagnosing acute mesenteric ischemia due to gas within the bowel lumen and potential limitations in visualizing the mesenteric vessels in larger patients [26].”
  • Every 6-hour delay in CT angiography doubles mortality rates in acute mesenteric ischemia.

    “as studies have shown that every 6 h delay doubles mortality rates [21,26].”

    From Revascularization Strategies for Acute and Chronic Mesenteric Ischemia: A Narrative Review (2024) · cites this paper as [26]

    The Introduction reports high mortality in mesenteric ischemia, and the diagnostic-imaging section recommends CTA as the first-line test. Neither passage, nor searches for a six-hour delay and mortality doubling, establishes that each six-hour delay in CTA doubles mortality. (LLM, conf=0.75)

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.
