Abstract: Objectives To differentiate brain metastases (BMs) from non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) and BMs due to the adenocarcinoma (AD) and non-adenocarcinoma (NAD) subtypes using radiomic features derived from multiparametric magnetic resonance imaging (MRI). Methods 276 patients with BMs, including 98 with SCLC and 178 with NSCLC, were randomly divided into training (193 cases) and validation (83 cases) sets in a ratio of 7:3. Of the 178 patients with NSCLC, 155 were from primar… Show more
