Synopsis

Keywords: Lung, CancerWe hypothesized that pulmonary MRIs with UTE using single- or dual-echo techniques may be equal to or more useful than standard-dose thin-section CT for evaluating solid portion size and C/T ratio. The purpose of this study was thus to compare capabilities of pulmonary MRIs with UTE using single- and dual-echo techniques (UTE-MRI_Single and UTE-MRI_Dual) and thin-section CT for quantitative differentiation of non- and minimally invasive adenocarcinomas from other lung cancers.
