Fig. 1From: Perilesional edema in brain metastases: potential causes and implications for treatment with immune therapyTumor volume weakly correlates with edema among NSCLC and melanoma patients. a Representative baseline MRIs taken from patients treated with pembrolizumab showing similar tumor volumes on T1 post gadolinium 3D MP-RAGE (white arrows) but discordant amounts of edema volume on FLAIR sequences. b The correlation between tumor and edema volume of NSCLC and melanoma BMs is weak. c Pre-treatment edema:tumor volumes are not significantly different in melanoma and NSCLC patientsBack to article page
