Foodborne illness affects an estimated 48 million people in the United States each year, and outbreaks peak in the summer. Recalls during the summer of 2026 involved eggs, jalapeños, and frozen blueberries, along with a Cyclospora outbreak traced to iceberg lettuce that caused more than 12,000 illnesses and over 550 hospitalizations. Furthermore, they caused nationwide public anxiety and dominated news headlines. Patients with enteric infection usually reach the emergency department with abdominal pain, and radiologists often read their CT before stool studies return or before anyone suspects infection. This review describes the CT findings of bacterial and parasitic enteritis and colitis. Common features include symmetric segmental or diffuse bowel wall thickening with submucosal edema, mucosal hyperenhancement producing a halo or target pattern, associated fat stranding, engorged mesenteric vessels, and lymphadenopathy. CT also shows complications including toxic megacolon, perforation, and abscess. Recognition of these findings supports timely diagnosis and appropriate management of infectious enterocolitis.
To synthesise evidence on the diagnostic performance, safety, feasibility and clinical impact of ultra-low-field portable magnetic resonance imaging (pMRI) in adult neurocritical care and intensive care unit (ICU) populations. PubMed, Scopus and Embase were searched from inception to 6 February 2026 and supplemented by grey literature and citation searching. We included original English-language studies of adult ICU, neurocritical care or emergency department patients undergoing pMRI at ≤ 0.1 T. Two reviewers independently screened studies and extracted data. Risk of bias in diagnostic comparisons was assessed with an adapted QUADAS-2 framework, and feasibility and safety outcomes were appraised narratively. Because of heterogeneity, findings were synthesised narratively. The review was prospectively registered with PROSPERO (CRD420261302014). Eleven studies published between 2020 and 2024 were included, comprising 694 patient participants and 715 patient examinations, plus 40 healthy controls. Cohorts overlapped substantially: six studies came wholly and one partly from a single institution, and one ECMO study was a subset of another. The number of unique patients is therefore estimated at 281 to 677. In the multicentre ECMO study, adverse events occurred in 3 of 50 patients (6
Radiographs are the first line imaging modality in evaluation for fractures, which can be challenging in equivocal cases with findings that mimic fractures. Accurate and quick identification of acute fractures is essential for triage, management, and prevention of complications. At the same time, overcalling a benign finding as a fracture can lead to patient anxiety and further testing that adds health care cost and time. As such, familiarity with fracture mimics is a critical skill for clinicians involved in emergency and acute care settings. This pictorial essay reviews common acute fracture patterns and highlights key imaging features that distinguish acute fractures from benign mimics, primarily through numerous representative cases. The article also provides a framework to address equivocal findings with next steps that can be performed for troubleshooting.
