EGFR and non-small cell lung carcinoma: This figure may even be improved using imaging multimodalities.25 A pre-treatment CT radiomic feature (Law’s Energy) in a cohort of 47 patients with early-stage non-small cell lung cancer (NSCLC) was significantly predictive for EGFR-mutation status.8 Interestingly, this study also showed that the difference in one radiomic feature (Gabor Energy) between baseline and an on-treatment CT (3 weeks after beginning the anti-EGFR gefitinib) was associated with mutation status.
