In resource-limited settings, accurate diagnosis remains challenging. Lung ultrasound (LUS) is an effective, low-cost diagnostic tool, however, its performance in smaller regional hospitals remains underexplored. We conducted a prospective observational study to evaluate the diagnostic yield of LUS among children hospitalized with WHO-defined pneumonia in Eastern Uganda. All children received a systematic 12-zone LUS by a trained operator using a linear probe in the sagittal plane. LUS was remotely interpreted by two blinded reviewers. Chest X-ray (CXR) was performed when feasible. We enrolled 46 patients with a total of 523 lung zones reviewed. The average age was 22\u2009months (\u00b1\u200926.8\u2009months); 67% of patients demonstrated hypoxemia. LUS was adequate in 42\/46 (91%) children. LUS identified pneumonia in 25\/42 (59%), bronchiolitis in 2\/42 (5%), and normal lung in 15\/42 (36%). CXR was completed in 40\/46 (87%) children and showed pneumonia in 18\/40 (45%). For the 36 children with both LUS and CXR, four (11%) demonstrated pneumonia on CXR but not LUS, compared to 11 (30%) who had pneumonia on LUS but not CXR. Our study demonstrated that LUS is feasible and identified features of pneumonia is 59% of LUS studies. While the overall diagnostic yield of LUS is comparable to CXR, a substantial proportion of children had pulmonary findings detected by only one imaging modality. These findings suggest a complementary rather than redundant role for LUS and CXR.<\/jats:p>","DOI":"10.1093\/tropej\/fmag065","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T11:36:14Z","timestamp":1788867374000},"source":"Crossref","is-referenced-by-count":0,"title":["Diagnostic
