Ground
Ground Glass Opacity
Ground Glass Opacity (pronunciation: /graʊnd glɑːs ɒˈpæsɪti/) is a term used in radiology to describe a specific appearance seen on Computed Tomography (CT) scans of the lungs.
Etymology
The term "Ground Glass Opacity" is derived from the appearance of the affected areas on a CT scan, which resemble the frosted or etched surface of ground glass.
Definition
Ground Glass Opacity refers to a finding on CT scans where the lung tissue appears hazy and less dense than normal, but without obscuring the underlying structures such as the bronchi and blood vessels. This is due to partial filling of air spaces in the lungs by inflammation, fluid, or cells.
