High-resolution CT image showing ground-glass opacities in the periphery of both lungs in a patient with COVID-19 (red arrows). The adjacent normal lung tissue with lower attenuation appears as darker areas. Ground-glass opacity (GGO) is a finding seen on chest x-ray (radiograph) or computed tomography (CT) imaging of the lungs.
Bat wing appearance is a radiologic sign referring to bilateral perihilar lung shadowing seen in frontal chest X-ray and in chest CT. [1] [2] The most common reason for bat wing appearance is the accumulation of oedema fluid in the lungs. [3] The batwing sign is symmetrical, usually showing ground glass appearance and spares the lung cortices. [4]
The shadows that accompany the ribs may mimic pleural and lung disease. [2] Scapular companion shadow overlie the scapula, with a smooth, well-defined margin parallel to the medial border of the scapula. The companion shadow results from unusual radiographic position of the scapula, which causes a soft-tissue fold to occur along its medial border.
It is seldom possible to reach a diagnosis on the basis of the chest radiograph alone: high-resolution CT of the chest is usually required and sometimes a lung biopsy. The following features should be noted: type of shadowing (lines, dots or rings) reticular (crisscrossing lines) companion shadow (lines paralleling bony landmarks)
Modern detail-oriented scans such as high-resolution computed tomography (HRCT) is the gold standard in respiratory medicine and thoracic surgery for investigating disorders of the lung parenchyma . Contrasted CT scans of the chest are usually used to confirm diagnosis of for lung cancer and abscesses , as well as to assess lymph node status at ...
A posterior-anterior (PA) chest X-ray is the standard view used; other views (lateral or lordotic) or CT scans may be necessary. [citation needed] In active pulmonary TB, infiltrates or consolidations and/or cavities are often seen in the upper lungs with or without mediastinal or hilar lymphadenopathy. [1] However, lesions may appear anywhere ...
