Pneumonia is considered a major healthcare problem that has a huge effect on the morbidity and mortality globally. It is considered one of the leading causes of death worldwide.
Any delay or failure in the diagnosis or management of pneumonia causes significant increase in mortality. Meanwhile, inappropriate antibiotic leads to the development of antibiotic resistance.
Traditionally, the diagnosis of pneumonia is reached using clinical examination, laboratory data, radiological techniques, and cultures. Clinical information alone is not enough to predict pneumonia.
Chest X-ray (CXR) is the easiest approach in patients with suspected pneumonia, in search for a new infiltrate. However, studies clarified that it has low sensitivity for the diagnosis of pneumonia in comparison to chest computed tomography (CT). But the use of chest CT is not commonly used except for complex cases and cases with failure response to treatment. Lung ultrasonography (LUS), being a fast bedside technique, it has attracted many interests to preform studies to assess its ability to detect pleuropulmonary pathologies generally and pneumonia specifically.
