350 A Study of Partial Volume Effect for Lung cancer Screening CT

CT screening for lung cancer.

Recommendations against screening for lung cancer were based on the lack of a reduction in mortality of the screened group as compared with the control group in randomized control trials. These results were interpreted as showing that early detection of lung cancer as a result of screening did not decrease the mortality rate compared with detection after presentation of symptoms for the populat...

CT screening for lung cancer.

CT screening for lung cancer.

To the Editor: The survival data from the International Early Lung Cancer Action Program (I-ELCAP) study of computed tomographic (CT) screening for lung cancer, as reported by Henschke et al. (Oct. 26 issue), are misleading.1 These estimates of survival are potentially confounded by lead-time and overdiagnosis biases of unknown magnitude and therefore defy meaningful interpretation. Although th...

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...
