ABSTRACT Background Despite advancements in vaccination and the transition from pandemic to endemic, SARS‐CoV‐2 continues pose a medical challenge, particularly among children. In this context, imaging diagnostics, such as chest x‐rays, are crucial initial treatment of patients. This study aims characterize radiological findings pediatric patients with confirmed infection Colombia between April 2020 November 2021, well describe clinical presentation, including those admission intensive care. Methods Colombia, multicenter cohort comprised aged 29 days 17 years X‐ray taken within 72 h hospitalization. two separate groups, four radiologists evaluated images. A fifth radiologist reviewed all X‐rays; subsequently, these readings were used calculate kappa coefficient solve discrepancies other radiologists. The results compared Results Analysis was conducted on 392 median age 2 years, majority whom (42%) infants. Sixty‐eight percent radiographs had normal results. Peribronchial thickening interstitial opacity most common aberrant (59%), followed by alveolar (12%). 88 bilateral. our cohort, peribronchial pattern found admitted PICU ventilatory failure. Interobserver agreement low for (kappa = 0.1), but higher consolidations opacities 0.4 0.5, respectively). Conclusion SARS‐CoV‐2, nonspecific interobserver is minimal. Although consolidation demonstrated greater concordance, they did not appear reflect presentation; therefore, can suggest radiography considered useful determining severity COVID‐19 There need more investigations.
