Magnetic Resonance-Based Texture Analysis Differentiating KRAS Mutation Status in Rectal Cancer

7 May 2019

Abstract excerpt

PURPOSE: Mutation of the Kirsten Ras (KRAS) oncogene is present in 30%-40% of colorectal cancers and has prognostic significance in rectal cancer. In this study, we examined the ability of radiomics features extracted from T2-weighted magnetic resonance (MR) images to differentiate between tumors with mutant KRAS and wild-type KRAS. MATERIALS AND METHODS: Sixty patients with primary rectal cancer (25 with mutant...
