Background and Objective. Chest X-ray is recommended for routine use in patients with suspected pneumonia, but its use in emergency settings is limited. In this study, the diagnostic performance of a new method for quantitative analysis of lung ultrasonography was compared with bedside chest X-ray and visual lung ultrasonography for detection of community-acquired pneumonia, using thoracic computed tomography as a gold standard.Methods. Thirty-two spontaneously breathing patients with suspected community-acquired pneumonia, undergoing computed tomography examination, were consecutively enrolled. Each hemithorax was evaluated for the presence or absence of abnormalities by chest X-ray and quantitative or visual ultrasonography.Results. Quantitative ultrasonography showed higher sensitivity (93%), specificity (95%), and diagnostic accuracy (94%) than chest X-ray (64%, 80%, and 69%, resp.), visual ultrasonography (68%, 95%, and 77%, resp.), or their combination (77%, 75%, and 77%, resp.).Conclusions. Quantitative lung ultrasonography was considerably more accurate than either chest X-ray or visual ultrasonography in the diagnosis of community-acquired pneumonia and it may represent a useful first-line approach for confirmation of clinical diagnosis in emergency settings.

Background: Lung ultrasonography is a new method for diagnosing community-acquired pneumonia. Lung ultrasonography has some advantages over chest X-ray, such as lack of ionizing radiation risk, bedside performance, and cost-effectiveness. Objectives: In this study, we aimed to determine the feasibility of lung ultrasonography in emergency settings in children with community-acquired pneumonia. Methods: The study included patients younger than 18 years of age with suspicion of community-acquired pneumonia. On the first evaluation, patients with positive clinical and/or chest X-ray findings were defined to have community-acquired pneumonia, and this was accepted as the gold standard. The chest X-rays were evaluated by the chief of the pediatric emergency department, who was blinded to the patients and the lung ultrasonography results. Lung ultrasonography was performed by another pediatric emergency physician who was also blinded to the chest X-ray results and clinical findings such as fever, respiratory distress, rales, and wheezing. Results: Of the 91 patients enrolled, 71 (78.0%) were diagnosed with community-acquired pneumonia based on clinical and chest X-ray findings. The median (interquartile range) duration of the lung ultrasonography procedure was 4.0 (3.5–6.0) min. Shred sign, air bronchogram, and hepatization were significantly more frequent in the patients with community-acquired pneumonia ( p < 0.01, p < 0.01, and p = 0.01, respectively). Sensitivity and specificity of lung ultrasonography were 78.5% (67.1–87.4) and 95.2% (76.1–99.8), respectively. Conclusion: Lung ultrasonography is a useful diagnostic method for children with suspicion of community-acquired pneumonia.

Objectives To compare the yield of early combined use of chest X-ray (CXR) and chest computed tomography (CT) in patients diagnosed with community-acquired pneumonia (CAP) presenting to the emergency department (ED) and assess the impact of chest CT on the initial diagnosis. Methods The medical records of 900 patients who presented to the ED and were diagnosed with CAP over a 1-year period were reviewed, and 130 patients who underwent CXR and chest CT within 48 hours were selected. CXR findings were classified as positive, negative, or inconclusive for CAP. Chest CT findings were defined as positive, negative, inconclusive, or positive with add-on to the CXR findings. CT was classified as having no benefit, large benefit, or moderate benefit based on the chest CT and CXR findings. Results Chest CT results were positive in 90.7% of patients, with 41.5% being newly diagnosed after negative or inconclusive CXR and 21.5% being diagnosed with add-on to the CXR findings. CT had large, moderate, and no benefit over CXR in diagnosing or excluding CAP in 45.3%, 21.5%, and 33.1% of patients, respectively. Conclusion Early chest CT may be used to compliment CXR in the early diagnosis of CAP among patients in the ED.

Abstract Background There is no consensus on the imaging modality to be used in the diagnosis and management of Coronavirus disease 2019 (COVID-19) pneumonia. The purpose of this study was to make a comparison between computed tomography (CT) and chest X-ray (CXR) through a scoring system that can be beneficial to the clinicians in making the triage of patients diagnosed with COVID-19 pneumonia at their initial presentation to the hospital. Results Patients with a negative CXR (30.1%) had significantly lower computed tomography score (CTS) (p < 0.001). Among the lung zones where the only infiltration pattern was ground glass opacity (GGO) on CT images, the ratio of abnormality seen on CXRs was 21.6%. The cut-off value of X-ray score (XRS) to distinguish the patients who needed intensive care at follow-up (n = 12) was 6 (AUC = 0.933, 95% CI = 0.886–0.979, 100% sensitivity, 81% specificity). Conclusions Computed tomography is more effective in the diagnosis of COVID-19 pneumonia at the initial presentation due to the ease detection of GGOs. However, a baseline CXR taken after admission to the hospital can be valuable in predicting patients to be monitored in the intensive care units.
