Invasive pulmonary adenocarcinomas versus preinvasive lesions appearing as ground-glass nodules: differentiation by using CT features
Purpose To retrospectively investigate the differentiating computed tomographic (CT)
features between invasive pulmonary adenocarcinoma (IPA) and preinvasive lesions
appearing as ground-glass nodules (GGNs) in 253 patients. Materials and Methods This
study was approved by the institutional review board. From January 2005 to October 2011,
272 GGNs were pathologically confirmed (179 IPAs and 93 preinvasive lesions) in 253
patients and were included in this study. There were 64 pure GGNs and 208 part-solid …

OBJECTIVE. The objective of our study was to investigate the potentials of enhanced dual-
source dual-energy CT (DECT) and three-planar measurements for differentiating invasive
pulmonary adenocarcinomas (IPAs) from preinvasive lesions appearing as pure ground-
glass nodules (pGGNs). MATERIALS AND METHODS. Thirty-nine patients with 53 pGGNs
who underwent enhanced dual-source DECT were included in this retrospective study. All
pGGNs were pathologically confirmed and categorized into two groups: preinvasive lesions …
