Pulmonary nodules: volume repeatability at multidetector CT lung cancer screening.
PURPOSE To assess in vivo volumetric repeatability of an automated software algorithm in pulmonary nodules detected during a lung cancer screening trial. MATERIALS AND METHODS This study was approved by an institutional review board. Written informed consent was obtained from all participants. Data were collected from the Multicentric Italian Lung Detection project, a randomized controlled lu...
متن کاملPulmonary nodules detected at lung cancer screening: interobserver variability of semiautomated volume measurements.
PURPOSE To retrospectively determine interobserver variability of semiautomated volume measurements of pulmonary nodules and the potential reasons for variability. MATERIALS AND METHODS The Dutch-Belgian lung cancer screening trial (NELSON) is a lung cancer screening study that includes men between the ages of 50 and 75 years who are current or former heavy smokers. The NELSON project was app...
متن کاملSmall pulmonary nodules: volume measurement at chest CT--phantom study.
Three-dimensional methods for quantifying pulmonary nodule volume at computed tomography (CT) and the effect of imaging variables were studied by using a realistic phantom. Two fixed-threshold methods, a partial-volume method (PVM) and a variable method, were used to calculate volumes of 40 plastic nodules (largest dimension, <5 mm: 20 nodules with solid attenuation and 20 with ground-glass att...
متن کاملMalignant versus benign nodules at CT screening for lung cancer: comparison of thin-section CT findings.
PURPOSE To evaluate thin-section computed tomographic (CT) characteristics of malignant nodules on the basis of overall appearance (pure ground-glass opacity [GGO], mixed GGO, or solid opacity) in comparison with the appearance of benign nodules. MATERIALS AND METHODS Institutional review board approval and patient consent were obtained. Follow-up diagnostic CT was performed in 747 suspicious...
متن کاملCancer in pulmonary nodules detected on first screening CT.
BACKGROUND Major issues in the implementation of screening for lung cancer by means of low-dose computed tomography (CT) are the definition of a positive result and the management of lung nodules detected on the scans. We conducted a population-based prospective study to determine factors predicting the probability that lung nodules detected on the first screening low-dose CT scans are malignan...
