Ground glass attenuationとは
Webincreased lung attenuation (areas of GGA) could be caused pathologically by patchy alveolar septal fi brosis. These findings suggest that areas of ground glass attenuation in U1P, as seen on thin-section CT, do not always correspond pathologically only to the areas of cellular infiltration but also to areas of interstitial fi brosis. WebFor example, smaller vessels in the lower attenuation areas are seen in mosaic perfusion, regardless of cause (i.e., air-trapping or vascular obstruction), and the vessels are of comparable size in both high- and low-attenuation areas in ground-glass opacity (Figs. 1A, 1B and 2A, 2B).

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. When a substance other than air fills an area of the lung it increases that area's density. On both x-ray and CT, this appears more grey or hazy as opposed to the normal… WebMar 29, 2024 · Ground glass opacity (GGO) refers to the hazy gray areas that can show up in CT scans or X-rays of the lungs.
