2020年4月10日 · Viral pneumonia occurs due to aggression of the viral pathogens on the lung structures. Because of the clinical manifestations and the radiologic aspects, viral pneumonia was included in the...

Chest x-ray findings may be normal in the early phase and show bilateral or unilateral parenchymal opacities with infective progression. The most common finding on CT is consolidation with or without ground glass opacity with subpleural and peribronchovascular predisposition as shown in a study of 104 immunocompetent patients with adenovirus ...

2023年7月4日 · Chest x-ray - As there is a tremendous overlap in findings on chest x-ray with both bacterial pneumonia and viral pneumonia, no one finding or set of findings is pathognomonic. Features that are suggestive of bacterial pneumonia include the following:

2024年5月8日 · 60% of community acquired pneumonia is diagnosed clinically without identification of a causative organism or imaging studies. Epidemiology. Pneumonia ranks 8th as a cause of death in the USA and is the most deadly of the infectious diseases. Poverty, age and access to vaccination and antibiotics are the main causes of global variation.

Rapid and accurate detection of viral pneumonia using chest X-rays can be of significant value for large-scale screening and epidemic prevention, particularly when other more sophisticated imaging modalities are not readily accessible.

2011年7月1日 · Imaging and clinical manifestations of viral pneumonia are protean and not reliably predictive of its origin. All patients with neutropenic fever and normal findings at chest radiography should undergo thin-section computed tomography to determine whether parenchyma abnormalities are present.
