Since pneumonitis manifests in all areas of the lungs, imaging such as chest x-rays and Computerized tomography (CT) scans are useful diagnostic tools. [3] While pneumonia is a localized infection, pneumonitis is widespread. [3] A spirometer may also be used to measure pulmonary function.
Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. [a] Identifying the responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination. [8] Chest X-rays, blood tests, and culture of the sputum may help confirm the diagnosis. [8]
A chest radiograph, chest X-ray (CXR), or chest film is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures. Chest radiographs are the most common film taken in medicine.
Lung cavity; Other names: Pulmonary cavity, lung cavitary lesion, lung cavitation: Chest X-ray of a person with advanced tuberculosis: Infection in both lungs is marked by white arrow-heads, and the formation of a cavity is marked by black arrows.
Pleuritis, pleuritic chest pain [1] Figure A shows normal anatomy. Figure B shows lungs with pleurisy in the right lung, and a pneumothorax of the left lung. Specialty: Pulmonology: Symptoms: Sharp chest pain [1] Causes: Viral infection, bacterial infection, pneumonia, pulmonary embolism [2] Diagnostic method: Chest X-ray, electrocardiogram ...
A routine chest X-ray is not always necessary for people who have symptoms of a lower respiratory tract infection. [4] Influenza affects both the upper and lower respiratory tracts. [citation needed] Antibiotics are the first line treatment for pneumonia; however, they are neither effective nor indicated for parasitic or viral infections. Acute ...
A: Normal chest x-ray. B: Abnormal chest x-ray with shadowing from pneumonia in the right lung (left side of image). Hospital-acquired pneumonia (HAP) or nosocomial pneumonia refers to any pneumonia contracted by a patient in a hospital at least 48–72 hours after being admitted. It is thus distinguished from community-acquired pneumonia. It ...
In some cases, chest CT can reveal pneumonia not seen on x-rays. However, congestive heart failure or other types of lung damage can mimic CAP on x-ray. [15] When signs of pneumonia are discovered during evaluation, chest X-rays and examination of the blood and sputum for infectious microorganisms may be done to support a diagnosis of CAP.
