Glossary of terms for CT of the lungs: recommendations of the Nomenclature Committee of the Fleischner Society.

Usefulness of Endobronchial Ultrasonography With a Guide Sheath and Virtual Bronchoscopic Navigation for Ground-Glass Opacity Lesions

“…In terms of radiologic characteristics, 2 types of GGO predominant type lesions can be identified: pure GGO is a lesion that has no solid component, while mixed GGO is a lesion that consists of heterogeneous attenuation with a solid component [6][7][8]. GGO predominant-type lesions on HRCT reflected a lepidic growth pattern of tumor cells microspically, related with presence of EGFR mutation and show slow growth over time [9][10].…”

Pulmonary Cryptococcosis with a Solitary Focal Ground-glass Opacity on High-resolution Computed Tomography

“…GGO is a nonspecific finding in the lung on CT, and has been defined as "hazy increased attenuation of lung, with preservation of bronchial and vascular margins caused by partial filling of air space, interstitial thickening, partial collapse of alveoli, normal expiration, or increased capillary blood volume (5)." To our knowledge, this is the first report of pulmonary cryptococcosis with a solitary focal GGO in the literature.…”

Clinical characteristics and computed tomography findings in Arab patients diagnosed with pulmonary sarcoidosis

“…CT reports collected from medical records were assessed for the presence of the following recognized CT patterns:10 (1) mediastinal and/or hilar lymph node enlargement, (2) ground-glass opacity, (3) consolidation, (4) nodules <3 cm in diameter, (5) thickening of bronchovascular bundles, (6) linear opacity including interlobular septal lines and interstitial thickening, (7) bronchial narrowing secondary to lymph node compression, (8) bullae, (9) and features indicating scarring and fibrosis (grouped together) that included the following: traction bronchiectasis, honeycombing, cysts, and/or volume loss. All CT scans were performed within 1 to 10 years after diagnosis (n=67).…”
