Atelectasis of the right lower lobe seen on chest X-ray. Clinically significant atelectasis is generally visible on chest X-ray; findings can include lung opacification and/or loss of lung volume. Post-surgical atelectasis will be bibasal in pattern. Chest CT or bronchoscopy may be necessary if the cause of atelectasis is not clinically ...
Chest x-ray demonstrating severe atelectasis or collapse of the right lung and mediastinal shift towards the right. Atelectasis is the partial collapse of a lung that is reversible. There are numerous etiologies, including post-operative atelectasis, surfactant deficiency, mucus plugging, and foreign body aspiration.
In case of a round atelectatic mass, the nearby bronchovascular bundle appears to be pulled into the mass, resembling the tail of a comet. The comet tail usually extends from a central point in the lung periphery towards the hilum. If intravenous contrast is injected, homogenous enhancement is seen. [2]
Peribronchial cuffing, also referred to as peribronchial thickening or bronchial wall thickening, is a radiologic sign which occurs when excess fluid or mucus buildup in the small airway passages of the lung causes localized patches of atelectasis (lung collapse). [1]
Positioning for a PA chest x-ray Normal lateral chest radiograph. Different views (also known as projections) of the chest can be obtained by changing the relative orientation of the body and the direction of the x-ray beam. The most common views are posteroanterior, anteroposterior, and lateral. In a posteroanterior (PA) view, the x-ray source ...
Ground-glass opacity (GGO) is a finding seen on chest x-ray (radiograph) or computed tomography (CT) imaging of the lungs. It is typically defined as an area of hazy opacification (x-ray) or increased attenuation (CT) due to air displacement by fluid, airway collapse, fibrosis , or a neoplastic process . [ 1 ]

It refers to the dilatation and abrupt change in calibre of a previously normal descending pulmonary artery on a chest X-ray film. [1] Chang sign usually appears within 24 hours of the onset of chest pain due to pulmonary embolism, [ 2 ] and the maximal dilatation of the descending pulmonary artery often occurs in two to three days after the ...
