CT of the lungs: A CT scan of the chest may be done to see finer details within the lungs and detect pneumonia that may be more difficult to see on a plain x-ray. A CT scan also shows the airway (trachea and bronchi) in great detail and can help determine if pneumonia may be related to a problem within the airway..
How does pneumonia show up on a CT scan?
CT findings in viral pneumonia are nonspecific and overlapping and consist of centrilobular nodules, ground-glass attenuations with a lobular distribution, segmental consolidation, and/or diffuse ground-glass attenuation with thickened interlobular septa..
What are the CT findings of pneumonia?
A CT scan also shows the airway (trachea and bronchi) in great detail and can help determine if pneumonia may be related to a problem within the airway. A CT scan can also show complications of pneumonia, abscesses or pleural effusions and enlarged lymph nodes..
What are the radiographic findings of bacterial pneumonia?
The chest radiograph shows bilateral opacities with a predominantly peripheral distribution. In most patients, radiographs demonstrate a patchy bronchopneumonic pattern, but segmental and lobar consolidation may be seen. Therefore, H influenzae pneumonia is indistinguishable from pneumococcal pneumonia..
What is the imaging of choice for pneumonia?
Chest radiography is the imaging technique of choice in evaluating patients with suspected pneumonia because of its low radiation dose, low cost, and wide accessibility..
Why do they do a CT scan for pneumonia?

Lung adenocarcinoma is a subtype of non-small cell lung cancer. On computed tomography (CT) it can appear as ground glass nodules, consolidative opacity, or solid mass lesions located in the periphery. Because it can appear as a consolidation, it can sometimes be confused with an infectious process such as pneumonia.
The chest radiograph shows bilateral opacities with a predominantly peripheral distribution. In most patients, radiographs demonstrate a patchy bronchopneumonic pattern, but segmental and lobar consolidation may be seen. Therefore, H influenzae pneumonia is indistinguishable from pneumococcal pneumonia.
Ground-glass opacities and consolidation are the main CT and X-ray features; the distribution of lung abnormalities is typically bilateral and peripheral. Less typical findings, including pleural effusion, mediastinal lymphadenopathies, the bubble air sign, and cavitation, can also be visible on chest CT.
The most common CT findings are septal thickening, bronchial wall thickening, mosaic perfusion, bronchovascular bundle thickening, interstitial nodules, andÂ
Medical condition
Community-acquired pneumonia (CAP) refers to pneumonia contracted by a person outside of the healthcare system. In contrast, hospital-acquired pneumonia (HAP) is seen in patients who have recently visited a hospital or who live in long-term care facilities. CAP is common, affecting people of all ages, and its symptoms occur as a result of oxygen-absorbing areas of the lung (alveoli) filling with fluid. This inhibits lung function, causing dyspnea, fever, chest pains and cough.
Computed tomography findings in pneumonia
Medical condition
Cryptogenic organizing pneumonia (COP), formerly known as bronchiolitis obliterans organizing pneumonia (BOOP), is an inflammation of the bronchioles (bronchiolitis) and surrounding tissue in the lungs. It is a form of idiopathic interstitial pneumonia.
Lung disease
Eosinophilic pneumonia is a disease in which an eosinophil, a type of white blood cell, accumulates in the lungs. These cells cause disruption of the normal air spaces (alveoli) where oxygen is extracted from the atmosphere. Several different kinds of eosinophilic pneumonia exist and can occur in any age group. The most common symptoms include cough, fever, difficulty breathing, and sweating at night. Eosinophilic pneumonia is diagnosed by a combination of characteristic symptoms, findings on a physical examination by a health provider, and the results of blood tests and X-rays. Prognosis is excellent once most eosinophilic pneumonia is recognized and treatment with corticosteroids is begun.
Pneumocystis pneumonia (PCP)
Medical condition
Pneumocystis pneumonia (PCP), also known as Pneumocystis jirovecii pneumonia (PJP), is a form of pneumonia that is caused by the yeast-like fungus Pneumocystis jirovecii.
Usual interstitial pneumonia
Medical condition
Usual interstitial pneumonia (UIP) is a form of lung disease characterized by progressive scarring of both lungs. The scarring (fibrosis) involves the pulmonary interstitium. UIP is thus classified as a form of interstitial lung disease.
