Peripheral groundglass density
WebOct 21, 2024 · A ground-glass density nodule (GGN) is a circumscribed area of increased pulmonary attenuation with preservation of the bronchial and vascular margins. A ground-glass density may be: partly solid (part of the ground-glass opacity completely obscures the parenchyma) non-solid (no completely obscured areas): pure ground-glass nodules WebGround-glass opacity (GGO) is a radiological term indicating an area of hazy increased lung opacity through which vessels and bronchial structures may still be seen. It is less opaque than consolidation, in which such structures are obscured 1. Most commonly, diffuse GGOs are associated with widespread inflammatory or infiltrative lung disorders 2.

WebGround-glass opacity (GGO) is a non-specific term defined by the Fleischner society as the presence on high-resolution computed tomography (HRCT) of a hazy increase in lung density, not associated with obscuration of the underlying vessels or bronchial walls; if vessels are obscured, the term “consolidation” is preferred [1].

WebGround glass means a hazy appearance of a patch in lung. usually seen when there is a lack of air. ie air is replaced by blood, mucous,fluid,etc. Problems - 6 mm is a bit big, multiple lesions doesn't make it easier too. So chances of a cancer has to be actively searched - either in lung / surroundings- like breast, esophagus, stomach etc. In both CT and chest radiographs, normal lungs appear dark due to the relative lower density of air compared to the surrounding tissues. When air is replaced by another substance (e.g. fluid or fibrosis), the density of the area increases, causing the tissue to appear lighter or more grey. Ground-glass opacity is most often used to describe findings in high-resolution CT imaging of the thorax, although it is also used when describing chest radiographs. In CT, the term refers to one …
