Core Tip
Core Tip: Definitive diagnosis of acute coronary syndrome (ACS) is sometimes difficult to achieve, especially in patients who present with atypical symptoms, normal initial biomarkers of myocardial necrosis, and normal or nondiagnostic electrocardiograms (ECGs). In order to avoid inappropriate management for this life-threatening event, clinicians should be aware that myocardial perfusion defect is more commonly detectable even on routine non-ECG-gated contrast-enhanced computed tomography performed in search of other pathologies. In this review, several essential points of image interpretation in diagnosing ACS on non-ECG-gated contrast-enhanced computed tomography has been described.
