Rampinelli C, et al. - To assess the morphology of screening-detected lung cancers at low-dose computed tomography (LDTC) and to evaluate inter-observer agreement in their classification researchers carried out this investigation. Retrospectively 273 screening-detected lung cancers were reviewed by 4 radiologists with diverse thoracic imaging experiences. Cohen’s K statistic was used to examine the inter-observer agreement, and for overall agreement modified Fleiss’ kappa statistic was used among the pair of readers. It was observed that an insignificant percentage of screening-detected lung cancers has a non-nodular/non-mass appearance at LDCT. The findings suggested that a missed or delayed diagnosis can be avoided by knowledge of various presentation.
