A ground glass opacity (GGO) is a radiographic finding that is defined as a hazy opacity that does not obscure underlying bronchial structures or pulmonary vessels on high-resolution CT. Ground-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.
