Introduction Immediate diagnosis of bowel necrosis in acute abdominal conditions is essential for proper treatment. Dual-energy computed tomography (DECT) has recently emerged as a tool to assess intestinal viability ischemia. However, DECT's diagnostic accuracy clinical practice remains undefined. Methods This single-center retrospective cohort study at Japanese tertiary care hospital assessed necrosis. We included patients who underwent emergency operations with ischemia from April 2013 March 2022. Patients without DECT were excluded. The reference standard was determined by surgical findings. Four evaluators (two residents and two specialists) independently reviewed images blinded confirmed diagnoses. calculated pooled individual sensitivity, specificity, likelihood ratios, accuracy. Results Twenty-eight included. Pooled sensitivity specificity 0.65 (95% confidence interval (CI), 0.52-0.77) 0.83 CI, 0.70-0.92), respectively. Residents demonstrated higher than specialists. positive negative ratios 3.76 2.02-7.00) 0.42 0.29-0.61). Overall 0.73 (95%CI, 0.64-0.81). Inter-evaluator agreement moderate (Fleiss' kappa, 0.42). Conclusion this setting. While clinically valuable, capability not definitive. To optimize potential, future research should employ disease-specific image reconstruction techniques provide specialized interpretation training.
