  2. Ground-glass opacity - Wikipedia

    en.wikipedia.org/wiki/Ground-glass_opacity

    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.

  3. High-resolution computed tomography - Wikipedia

    en.wikipedia.org/wiki/High-resolution_computed...

    The lung bases are often inconsistent in appearance in patients due to the potential for atelectasis causing positional ground glass or consolidative opacities. When the patient is positioned prone, or on their belly, the lung bases can expand further and help distinguish atelectasis from early fibrosis. In patients with normal chest ...

  4. Chest radiograph - Wikipedia

    en.wikipedia.org/wiki/Chest_radiograph

    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 ...

  5. Lung nodule - Wikipedia

    en.wikipedia.org/wiki/Lung_nodule

    Ground glass opacity: No routine follow-up: CT after 6–12 months to check if persistent, then after 2 years and then another 2 years Part solid No routine follow-up: CT after 6–12 months: If unchanged and solid component remains <6mm: Annual CT for 5 years. Solid component ≥6mm: highly suspicious; Multiple nodules CT after 3–6 months.

  6. Usual interstitial pneumonia - Wikipedia

    en.wikipedia.org/wiki/Usual_interstitial_pneumonia

    There may be superimposed CT features such as mild ground-glass opacity, reticular pattern and pulmonary ossification. Probable UIP pattern: [4] Predominantly subpleural and basal; Often heterogenous distribution; Reticular pattern with peripheral traction bronchiectasis or bronchiolectasis; There may be mild ground-glass opacity; Indeterminate ...

  7. Ground glass - Wikipedia

    en.wikipedia.org/wiki/Ground_glass

    In motion-picture cameras, the ground glass is a small, usually removable piece of transparent glass that sits between the rotary disc shutter and the viewfinder. The ground glass usually contains precise markings to show the camera operator the boundaries of the frame or the center reticle, or any other important information. Because the ...

  8. Ground glass hepatocyte - Wikipedia

    en.wikipedia.org/wiki/Ground_glass_hepatocyte

    Micrograph showing ground glass hepatocytes. H&E stain. In liver pathology, a ground glass hepatocyte, abbreviated GGH, is a liver parenchymal cell with a flat hazy and uniformly dull appearing cytoplasm on light microscopy. The cytoplasm's granular homogeneous eosinophilic staining is caused by the presence of HBsAg.

  9. Halo sign - Wikipedia

    en.wikipedia.org/wiki/Halo_sign

    The halo sign is also understood as a region of ground-glass attenuation surrounding a pulmonary nodule on an X-ray computed tomography (CT scan) of the chest. It can be associated with hemorrhagic nodules , tumors , or inflammatory processes, but is most commonly known as an early radiographic sign of invasive pulmonary infection by the fungus ...
