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.
The non-fibrotic form is typically characterized by ground glass opacities, mosaic attenuation, ill-defined centrilobular nodules (<5 mm), and air trapping. [12] The fibrotic form is typically characterized by irregular linear opacities/coarse reticulations, traction bronchiectasis , and honeycombing , patchy ground-glass attenuation ...
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 ...
The most common findings on HRCT are diffuse hyperdense ground-glass attenuation and subpleural linear calcifications, often most predominant in the inferior and ...
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 ...
Scientists have found the U.K.’s largest dinosaur footprint site ever. The tracks were discovered in a quarry in Oxfordshire — about 60 miles northwest of London — by quarry employee Gary ...
The attenuation in the signal of ground motion intensity plays an important role in the assessment of possible strong groundshaking. A seismic wave loses energy as it propagates through the earth (seismic attenuation). This phenomenon is tied into the dispersion of the seismic energy with the distance. There are two types of dissipated energy:
"Lowering drug prices is a focus area for both Republicans and Democrats, and Chinese CDMOs [manufacturers] such as Wuxi Group play a key role as it helps the US pharma cut costs by 30-60%.
