Is often underestimated, if not driven by clinical suspicion, due to the non-specific clinical symptoms (usually represented by acute abdominal pain) and the absence of reliable markers, which results in a poor prognosis and high mortality. We can identify three main forms of AMI: arterial, venous, and non-occlusive. Arterial AMI is the most frequent form, caused by occlusion of the superior mesenteric artery or one of its branches. Venous AMI is the least frequent, caused by thrombosis of the superior mesenteric vein or its branches. Non-occlusive AMI is due to a state of hypovolemia, which is frequent in patients who have undergone surgery. Given the difficulty of diagnosis based on the clinic alone, the radiologist plays a central role in identifying radiological signs of intestinal ischemia and in avoiding misdiagnosis. The radiologist\u2019s role is mainly to identify factors predictive of necrosis, which allow us to stratify patients and direct them towards the proper management. The aim of this review is to provide indications for an adequate CT protocol, including an unenhanced phase, an arterial phase, and a venous phase, as well as to underline the features to investigate in the different forms of AMI, in order to increase the diagnostic capacity in this challenging disease.<\/jats:p>","DOI":"10.3390\/diagnostics16020332","type":"journal-article","created":{"date-parts":[[2026,1,20]],"date-time":"2026-01-20T11:27:58Z","timestamp":1768908478000},"page":"332","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The Importance of Predicting Bowel Necrosis in Acute Mesenteric Ischemia: Narrative Review"],"prefix":"10.3390","volume":"16","author":[{"given":"Caterina","family":"Giannessi","sequence":"first","affiliation":[{"name":"Department of Radiology, Careggi University Hospital, Largo Brambilla 3, 50134 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7028-9047","authenticated-orcid":false,"given":"Diletta","family":"Cozzi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Careggi University Hospital, Largo Brambilla 3, 50134 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-8547-8404","authenticated-orcid":false,"given":"Ludovica","family":"Scalzone","sequence":"additional","affiliation":[{"name":"Department of Radiology, Careggi University Hospital, Largo Brambilla 3, 50134 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesca","family":"Treballi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Careggi University Hospital, Largo Brambilla 3, 50134 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matilde","family":"Anichini","sequence":"additional","affiliation":[{"name":"Department of Radiology, Careggi University Hospital, Largo Brambilla 3, 50134 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Barbara","family":"Sessa","sequence":"additional","affiliation":[{"name":"Department of Radiology, San Filippo Neri Hospital, Via Martinotti 20, 00135 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Ferrarelli","sequence":"additional","affiliation":[{"name":"Department of Radiology, Great Metropolitan Hospital \u201cBianchi-Melacrino-Morelli\u201d, Via Giuseppe Melacrino 21, 89124 Reggio Calabria, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7109-8119","authenticated-orcid":false,"given":"Ginevra","family":"Danti","sequence":"additional","affiliation":[{"name":"Department of Radiology, Careggi University Hospital, Largo Brambilla 3, 50134 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7848-1567","authenticated-orcid":false,"given":"Vittorio","family":"Miele","sequence":"additional","affiliation":[{"name":"Department of Radiology, Careggi University Hospital, Largo Brambilla 3, 50134 Florence, Italy"},{"name":"Department of Experimental and Clinical Biomedical Sciences \u201cMario Serio\u201d, University of Florence, 50121 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"150","DOI":"10.1177\/14574969211007590","article-title":"Acute Mesenteric Ischemia: A Challenge for the Acute Care Surgeon","volume":"110","year":"2021","journal-title":"Scand.
