Ground-glass opacity on thin-section CT: value in differentiating subtypes of adenocarcinoma of the lung.

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]. Therefore, patients with GGO predominat-type lesions have been reported to have a good prognosis [11][12][13].…”

Accurate Diagnosis of Peripheral Small Cell Lung Cancer with Computed Tomography

“…Most of the non-solid masses are considered as well or moderately differentiated adenocarcinomas (Kuriyama et al 1999;Takashima et al 2003). In contrast, non-calcified solid masses may be benign or malignant lesions (Munden et al 1997;Henschke et al 1999;Bastarrika et al 2005).…”

Correlation in histological subtypes with high resolution computed tomography signatures of early stage lung adenocarcinoma

“…While on CT scans, these indolent and less aggressive tumors of AIS, MIA, and lepidic predominant adenocarcinomas frequently present as pure ground-glass opacity (pGGO) or mixed groundglass opacity (mGGO) (5). Several other studies confirmed a well correlation between CT findings and histologic prognostic factors in lung adenocarcinomas (5)(6)(7). However, when pGGOs are greater than 15 mm in diameter or have high pixel attenuation (>−472 HU), the nodules are more likely to be IA (8).…”
