From: Defining a Radiomic Response Phenotype: A Pilot Study using targeted therapy in NSCLC

Patients included to the study were received Gefitinib treatment. CT scans at baseline and first follow-up were used to segment the tumor and to extract radiomic features. Baseline, follow-up, and delta radiomics (differences between baseline and follow-up) were used to assess EGFR sensitizing mutation status.
